IT may interest u to take photographs indoors, after some time of clicking. but for this u will need some basic equipments which may not be expensive, particularly, when the work is done on part time basis.
ALTHOUGH many pro shots of food and still life are taken with single light and a number of reflectors. but for portraits, still life again, and fashion, maximum 3 nos. of lights are sufficient. however, for more complex arrangements, u will require more lights.....next imp. accessory is a stable tripod with adjustable centre column. if u use flash lights in studio, then a flash meter well be of great help for accurate reading of light and exposure.
FLASH exposures are determined by the power of the flash, which is expressed by the GUIDE NO. ....IF A FLASH HAS A GUIDE NO. OF 40(IN FEET) for an ISO 100, the exposure can be determined by dividing the guide no. by the distance from flash to the subject. ...e.g. if the subject is 5 feet away, u wud require an aperture of f8.........object that are further away will get underexposed while those closure will be overexposed....suppose u double the distance between the subject and the camera, the light falling on it will be half the amount....a remedy to this cud be to keep all objects included in the picture at the same distance from the camera. and in order to get shadow details, u cud inclide ambient light..........most imp PRO STILL LIFE shots are the product shots. for such a shot, lighting is used more to reveal shape and texture. however, sometimes a harder light such as a spot light wud be required for surface textures......mirrors/aluminium foils cab be used to highlight certain areas whenever required.
STILL life photography is in itself a comprehensive subject. if some one wants to master it, he will have to practice a lot. besides, reading books on the subject by the masters.......thanks........(gshroti@ in.com).

PHOTOGRAPHY-ARTIFICIAL LIGHT--2
USE OF AVAILABLE LIGHT:
During low light conditions, u will face the problem of sufficient lighting and wud run for the flash lights. however, it wud not be possible always, such as taking photographs at public functions, theatres, in restaurants and other interiors. here u will have to adopt shooting in the available light at that place, as even the camera flash will bring artificiality in the natural existing atmosphere. besides, u will have to resort to available light sources when shooting illuminated buildings and night scenes of the roads, of city, fireworks, during festivals etc.
While going to shoot such subjects, u will have to keep in mind certain conditions. first will be the level of light, which well be very low and in that case, u will have to use higher ISO, slow shutter speed and wide apertures. this will further necessitate using either tripods, monopods or some solid supports. this will stand good for static subjects, but for moving subjects, u will have to use a faster shutter speed, with higher ISOs and maximum apertures. no doubt, this may result in loss of quality and enhancing the noise, but ur ultimate goal wud be to catch the mood of the atmosphere. here in many cases the AUTO WHITE BALANCE will suffice, because u r not going to match the ambience atmosphere with that of daylight. ....rather this will contribute to ur photograph........while shooting night scenes, sometimes u may like to freeze ur subject or sometimes show blurryness. for freezing purpose, however a little bit higher shutter speed will be required. ...........and the another best time to shoot night pictures is at dusk, just before the sky loses all its light. this will help in getting the less contrasty results.

PHOTOGRAPHY IN ARTIFICIAL LIGHT
IT is a general notion to shoot pictures in available light by general public, amateurs etc...however, using artificial light will increase chances of opening new picture-taking possibilities.....a tungesten lamp or tubelight is the simple and most inexpensive piece of lighting equipment available in the house/working place.....in B&W, it is easier to take photos using this system....but in colour it is different....however, the dcam mfrs. have given the facility of white balance in these lights.....only thing is, the exposure will be longer and tripod is a must....in B&W times, we used two small tubelights in tin reflector and wonderful diffused light we got....
NOW the times have changed....there are photofloods and halogens, but with high intensity of light plus the problem of colour correction does not allow them useable. ..so now comes before us the easy alternative in the form of STUDIO FLASH. this is used by pros. in their studios and outdoors in weddings too....there is a flash tube and model tungsten bulb fitted in flash unit, which shows the accuracy of the flash light on the subject. ..using this will match the colour quality with that of daylight. so no need of colour correction. and next benefit is its high speed (almost 1/1000th of a second, which is sufficient to freeze any subject movement, thus giving the sharpest of image.
TO get DIFFUSED LIGHT, u will need an white umbrella or a soft box(of different sizes). in using umbrella, it is opposite. first the tube will throw light on the umbrella which will be reflected back on to the subject. in soft boxes, it is direct and provides diffused light.....besides there are attachments for concentrated light (such as on hairs/backgrounds as it is or with coloured gelatins), i.e. honeycomb grids and snoots, as suits to ur requirements. ...another thing u will require is white reflectors, may be white sheet or thermocol to fill in the lighting, or a black card sheet to slightly darken the effect, placed close to the face as per intensity, which u can view on ur LCD. ....before the coming of dcams, the pros. used polaroid cameras to preview the effect of light then make changes, if necessary and shoot the pix.....(to continue)....(gshroti@gmail.com).

LIGHTING--PHOTOGRAPHY'S LIFE--5
MEDIUM LIGHT SOURCE:
TILL now u went thru bigger and smaller sources of light. in between these two extremes, there will be a range of infinite light sources. u just imagine a source positioned exactly between the bigger and smaller light sources and which is defined as a medium light source.
Medium light source gives directional light, but with softer shadows than that created by smaller light source. ...........this kind of lighting is excellent for PORTRAITURE as well as table-tops for illustrating gradation and form. Texture also is more distinct. ........shiny objects get especially well-lit as the high-light is well shaped. contrast is generally high and cud be reduced by using a bounce flash.
LET me clear ur curiosity about medium light.........here one of the most easily available medium light source lighting with natural light is a diffused window light. and outside comes the filtered sunlight during monsoon, which comes through a part of giant cloud, which becomes a big diffuser........and we refer as a medium light source....this can be under ths shadow (well-lit) of a tree and in house a covered verandah, where u can do manipulations by turning the subject and using a white thermocol as a reflector for any subject within its reach giving different ratios of light and shade. also can be used near an open door......this light is soft and gradual. this kind of loghting is best for portraiture. under this light, when shooting during morning or evening, a pale blue tinge may be caught......that can be done away with, UV or 1A skylight filter. or that can be corrected in post processing, if necessary......Thanks.......

LIGHTING--PHOTOGRAPHY'S LIFE--4
SMALLER LIGHT SOURCE:
THIS light source is directional and casts hard-edged shadows. the sun is a small light source and its rays form harsh shadows.......as opposite to bigger light source, though also this source is bigger light source, it is so far away that it appears to be a smaller light source.
SMALL light sources are excellent in rendering texture and form. used in the right manner, direct sunlight can emphasise parts of a picture or the shape of an object.. on the positive side, smaller light sources inject life into small and simple objects with its direct-throw of hightlights and sharp shadows.......contrasts increase and many interesting effects can be created only with small light sources.
APART from texture, contrast and its ability to pick out natural visual patterns, smaller light sources create pointing and harsh highlights on objects. form tends to be more pronounced with this kind of lighting.. ..however, when the highlights add to the form and depth of an object, strong hightlights can be the cause of glare and distracting the metering system of the camera. despite the drawbacks, the glare can be removed by use of polariser and use of lenshood......this sort of lighting can make colours look brighter and vibrant..........however working with this type of lighting usually needs a certain amount of pre-planning.......(to continue).......(gshroti@gmail.com).

LIGHTING--PHOTOGRAPHY'S LIFE--3
BIGGER LIGHT SOURCE:
THIS is characterised by light falling on a subject from all directions. this type of light hardly casts any shadow and is generally referred to as soft or diffused light. this light works well for some kind of portraits and table-tops. the lighting, being from all directions is more or less flat. a bigger light source limits depth & reduces the three- dimentional effect..............THE most common example is an overcast sky. the light is soft even and does not throw shadows and hardly creates any sort of highlights on objects. the texture is subdued and the contrast is lower. .....one of the interesting feature of this type of lighting sources is that they create excellent and even reflections on glossy surfaces. a shiny subject and the reflections of the surroundings off the subject can be photographed far more effectively due to almost non-existent highlights on the object as well as in the reflections.
OVERCAST days are ideal for taking pix of people as soft light flattens skin tones. however, this kind of lighting has limitations as well. because there are no shadows, objects tend to appear flat and without depth. general scenes too tend to lose out on depth. the use of a good composition is necessary to depict depth more effectively in such photographs where the light comes from a vast area..................(to continue)..........(gshroti@gmail.com).

LIGHTING--PHOTOGRAPHY'S LIFE--2
DEFINE good lighting?...........the most difficult question, if asked to define good lighting. the good lighting for a given moment, cannot be defined.....different situations require different kind of lighting. ...LIGHTING for a table-top is different for lighting for portraits. in the same way, when talking about lighting for landscapes, the lighting for a mountain-side will not be suitable for buildings or a seashore/beach. this is the place where an expert photographer can show his capability.
MANY people may think that the natural lighting cannot be controlled. here the question to the newbies and the experienced photographers may put in dilemma how one can control the existing natural light. however, the fact is that the natural light can be controlled and used in a variety of ways.
THE light falling on the subject can be softened by allowing it to pass through a diffuser such as a translucent sheet of plastic, or a paper. by varying the degree of translucency of the diffuser, the degree of softness of the light can also be altered......the mirrors or different polished or reflective surfaces can be used to redirect light into the frame. however, reflectors can be of many types. ..a simple mirror can be used as reflector that can redirect almost 100% of the light. a crumpled piece of foil redirects the light but the effect will be softer than that of mirror........GOLD reflectors can be used to achieve a warmer effect. others, such as white paper/thermocole can be used as effective reflectors to redirect natural light. next we may think of controlling natural light is by using a flash gun as fill-in, wherein the natural light behaves as the main source of lighting the subject. u might have witnessed the big reflectors on the TV,while shooting serials/films, being used to throw back the natural light on the subjects, either as main light(such as in shooting against light) or as fill in from sides/fronts, or mirrors to enhance the hair-lighting........to continue......(cgshroti@ymail.com)

LIGHTING--PHOTOGRAPHY'S LIFE
ANY writing, essay, or blog shd first consider this aspect of photography:what is lighting, how lighting affects photography, photography cannot be imagined without light, sources of light, effect of light on films/sensors, how images are made.........there are several questions without answering/understanding them, u cannot start photography because light is the main component in the success or failure of photography.......the light is such a powerful tool,... that appearance of a person or object can change a lot with the change in direction and source of light....the perception of light does not involve just the source of light but also the quality of light.
LIGHT is a most strong element that affects every stage in the image making process.....visible lighting is just a part of electromagnetic spectrum(energy travelling in wave form). if any of the wavelengths are filtered or absorbed, we get a definite colour and the colour quality of light also varies with the position of the sun in the sky. for example, at sunrise or sunset it is warmer, due to absorption of longer wavelengths.

RULE OF THIRDS --PHOTOGRAPHY
USually the photographers are unaware of certain rules which shd dominate their composition.......otherwise the photographs will satisfy u only and not the publishers/competition judges.........and u will never come out of
that well......HERE i relate for ur benefit the most imp of all rules-RULE OF THIRDS--.........this is the most used compositional guideline. this rule was initially used by painters to create proper visual balance in their paintings..................photography has borrowed from this and used this rule to define visual balance in a photograph.
DIVIde the picture horizontally and vertically into thirds......the main subject of interest of your photograph shd be within the four intersection points of the diagram..........generally, the ease with which this rule can be applied depends upon the subject as well as the situation. .........the rule of thirds cannot be used easily with landscapes because the object within the frame cannot be moved.........what can be done, however, is that the perspective and position of the photographer can be changed to allow for the rule to apply so that the photograph shd be visually appealing to the viewer.....however there are different branches in photography, where this rule can 'rule' easily and effectively to save photograph being disintegrated.

SHOOTING FIREWORKS
THere are moments, when u cannot keep your camera in almirah. ...and that is the time shooting fireworks after sun sets......more than 75% of the photographers i met were curious of shooting fireworks.............................SNAP up beautiful fireworks using a d-cam with a shutter speed longer than 1/2 a second. ideally choose a shutter speed 2 to 10 seconds to capture all the sparkle. most essential, u will require a TRIPOD to avoid shaky, haphazard photos. so are the dangerous, the vibrations. if remote shutter release can be used, the better, otherwise a long lockable cable release may be the best alternative.
SET ISO setting to the lowest to reduce noise/grains. .....preview the shot on the LCD panel and accordingly adjust the aperture(shutter speed /aperture combination). while viewing fireworks on LCD screen, u will understand which aperture will be best for shutter speed of say 1/4 sec.so u can try f8,f11,f16 and take the shots to get the bright sharp photos.
FOR multiple fireworks u can use bulb setting, but be cautious to close the shutter, or put the lens cap over the lens, if used, as soon as the multi-bursts are out, to be at safer side..............u can shoot from a distance also to include the city lights, river, bridge etc which are already lighted by the city lights.........in this setting, if the bursts are many at side-by-side, u will get a good capture........so a simple but creative/lucrative happening for ur photography......good luck.

CANDIDS OF A CHILD.
PHOTOgraphing a child in his or her own element can capture a level of innocence that u never achieved with a 'posed' shot. ......take snapshots while the child is playing, watching tv, reading, jumping or just about doing anything..............you may never know where u may strike a gold and get that shot of a lifetime.

AUTOMATIC FLASH IN PRACTICE
AUTOmatic or computer flash units are designed to give correct amount of flash illumination for subject of various distances without the need for calculations based on a guide no............They do this by adjusting the duration of the flash automatically according to the subject range.
BEcause an auto flash guages the exposure according to the amount of light reflected from the subject, it also automatically takes into account the overall lightness or darkness of the scene in front of it. When the light sensor reads that the subject has received the enough light for the ISO set and aperture in use, it cut off the light.
SO all thing being equal, the closure the subject is to the camera, the shorter the total flash duration. u just set an aperture to suit your ISO speed, and keep that aperture for all distances within the flash range and your subject will be correctly exposed. ........what the newbies do. they set the aperture at f5.6 and flash on auto at f.5.6 at ISO 100, they go on exposing and slightly increase the aperture to f4, f3.5 in long distances (12 to 15 ft above) and get the correct exposure.......nowdays the ultimate weapon is the auto flash gun for photographers.

COLOUR BLUR
DEliberate waving around of the camera during longish exposures can produce very attractive abstract photographs. this works more successfully usually with colour rather than b&w,
THe different colours can paint an exciting abstract image when abstract tonal variations are seldom interesting. this will quench the thirst of the photographers who wish to experiment for abstract creation of images rather than direct capturing of images. on one site, I noticed that photographers were craving for abstract photographs but unable to do so and many a times confused realistic photograph as abstract. abstract in photography is a different dimension than paintings. still creation is a creation whatever the medium. modern day d-cams have sufficient opportunities to experiment and make colour abstracts. this i have seen in some exhibitions. the competition organisers may keep one section as ''Abstract Photography'' in colour.

PHOTOGRAPHY FOR U--SHOOTING DIFFERENT SKIN TONED PEOPLE.
IT is a normal practice with every unexperienced photographer , how to expose people, particularly with dark skin tones and light skin tones. naturally when u meter towards these subjects, the fluctuations will occur in your camera or external meter.......meter is light sensitive and as u wud expect, the lighter subject reflect light and the dark one absorbs it............suppose u set the meter correctly taking the meter reading from your palm, which is of normal tone. ....now move your lens towards a almost white skin tone of a girl, such as 'Kashmiri girl'..........u will see that your meter goes up showing overexposure......now turn the lens towards a dark complexioned girl,..........ur meter will go down, showing under exposure...........then how to take correct exposed skin texture of both the girls.............very natural, if u have read some lessons of photography...........underexpose by half to one stop for the white skinned girl and overexpose in the same way for the dark complexioned girl to get the correctly exposed photograph............yes, in general group give the exposure demanded by the camera's exposure meter where different complexioned people are there(in shadow).
seeing the different coloured people, group, may be students or general people in shadow, i bring down my camera's exposure towards a little bit darkerened road, or go close to the person of middle range skin tones take reading and and then shoot.

USE OF D-PHOTOGRAPHY
DIGItal photography benefitted many fields, in which the uppermost is Journaliasm where the photographs are now immediately transmitted from the site they have been taken,over the Internet, telephone lines,wireless connections and can be used for newspapers in a low resolution than required in magazines/brochures and many branches of publications.................NEXT is the MULTIMEDIA applications such as software packages,corporate presentations, television and ad agencies, production houses amd much more......others are GRAPHIC illustrations, like posters, books, mags,journals, reports etc., besides...............copying old photographs..............COMMERCIAL photography by renowned photographers using large format cameras even, giving quality equivalent to films............ FOR web publishing, badges, buttons, business cards, astronomy and the most of all in SPACE exploration and many fields.

SEE BACK......
I HAVE given briefs of digital cameras as u have seen in earlier pages........TO come out from the machinery, let us see how the machinery can be used for your creative purpose:
i have written in the title 'see back'............it is not your back but subject's back who is before your camera. this is the thing mostly overlooked by the photographers in order to be busy with their subject alone, not what is surrounding it................here I WILL SUGGEST that u shd check your the image in your viewfinder properly, before clicking the photograph. place your subject keeping the background in mind..................look out for tree, or electric/telephone poles sprouting from your subject's head. cluttered background will be distracting. therefore, in order to take good photo in one go, choose your background carefully...........................PLAIN BGs will help emphasise your subject beautifully, since at that time your full attention will be on your subject...........thanks God if she be your girlfriend, then double attention will be required for clicking one shot.so i plead that u be conscious of your photo's background more than as much u are interested to take your well planned shot...................

D-CAMERAS--7
CATEGORIES............WE can categorise the d-cams in 3 categories.................CONSUMER P&S cameras...........they come in the category of compacts and have features limited to a certain extent. howver many of them provide, video facility with sound. now with the advancement, they are also having 7,8,10 mehapixels, no dounr though pocketable generally with 3x optical zoom and 4x digitam zoom.so u can get prints upto 8x12 without noise..............PROSUMER CAMERAS..............they look like 35mm film cameras and have built-in lens and all the features of an advanced camera including large LCD and moveable in some cameras, like handicams. their demand is high because of prices and all features and long range zooms say 28-504mm, 36-432mm, in other words 10x, 14x, 18x and 20x zooms. the also work as a second camera for the serious enthusiasts and pros. DSLR CAMERAS ....they are the brother of old 35mm film cameras. the sensor has taken place of the film and being digital, different features, big LCD panel have been added and have same facility of programmed shutter, shutter priority, aperture priority, and manual settings plus an array of other feature to make them a really digital cams.....their beauty is that they can take good photos in low lighting conditions. built in small flash is a compulsory feature.

D-CAMERAS--6
ENgineers were eager to put several features in d-cams and lo...........one camera.............features galore. most and first was the automation. autofocus brings the centre of interest into sharpfocus. further, the WHITE BALANCE adjusts the colours according to the source of light. auto FLASH fires automatically, if the light is low...AUTO ADVANCE prepares the camera for the next photographs.
STorage of images.........................the number of images u can store in a camera depends upon a variety of factors. .....the no. u can store is important, because once u reach the limit, u have no choice but to quit taking of pix and if necessary, erase some of the images to make room for the new.....ALL dcams use some sort of storage system, such as built in MBs, flash memory cards. after the card is full, u can insert another or reduce the resolution and take more pix in low MPs.
TRansfering images to a computer. the memory card holds images upto a particular extent. and to make space again in it, u have to transfer them to your computer thru cable (USB) DIRECT FROM YOUR CAMERA OR ALTERNATIVELY use CARD READER device, in which u insert your flash card/SD/MMC/memory stick cards and download the images into the computer.
VIdeo output................u can use NTSC/PAL to attach your camera to a television to view your images more clearly and also for home/family viewing.

DIgital refers to the binary representation of data as bits and bytes. basically the binary representation of data is used by computer to create, manage and store information.
Bits and Bytes:a bit is the smallest unit of information that a computer can store and process and there are 8 bits in a byte.............PIXEL..is the smallest addresseable point of bitmapped screen that can be independently assigned colour and intensity................BITMAP is a digital representation of a picture in which all the dots or pixels making of the picture are placed in a square grid and correspond to specifically assigened bits in computer memory..................RESOLUTION..IS THE DEGREE OF SHARPNESS of an image displayed on a computer screen or quality of printed output expressed in dots per inch(dpi). resolution is usually equated with quality. the higher the resolution, the higher the image quality. .................COMPRESSION..is a data storage scheme in which data files are compressed by algorithms to save disk space.......................SOFTWARE DRIVERS..are files that allow your computer to communicate with peripheral devices such as scanner, digital camera, printer and modem.............

THe image sensor in d-cams has an impact on the images u shoot. this image sensor is the permanent part of your d-cam. these sensors, like films, render colour differently, have different amounts of grain, different sensitivities to light etc.
RESOLUTION..... this refers to the sharpness and details in an image. thereby the companies are now capable of producing higher resolution cameras like 6 to 10 megapixels. higher the resolution better the pictures and also for purpose of good enlargements.
SENSITIVITY:..........like films the companies have adopted the same type of range for sensitivity of the sensors i.e. ISO. like films lower ISO sensitivity gives better results and if the ISO is increased, the quality suffers and grains (n0ise) appear more prominently. for instance, the ISO ranges from 100 to 3200. ..........and like films lower ISO needs more light than higher. so while shooting, check the ISO according to the density of light i.e. low light will need higher ISO AS OPPOSITE TO LOWER ISO suppose in sunlight.
ONE MORE thing to point out is that higher resolution(more megapixels) reduces the number of images to be recorded by a d-cam. while lower image quality(low resolution--less megapixels)allows u to store more images and that depends upon the necessity of shooting pix.

D-CAMERAS--3
DIgital cameras are are not just cameras but more than that. generally we expect still photographs but using d-cams, u also get video with sound. this is a unique feature in small d-cams...........u can shoot like video. coming in this category, they became more like multimedia recorders than cameras. however, they still retain some features of film cams e.g. shutters and exposurers and lenses besides their own loads of new features, that include replacement of films by solid-state image sensors and they are divided in two categories i.e. CCD and newer CMOS image sensor.
OPerating system: .............the d-cam needs an operating system like the computers and this software works for image compression, file storage, image display and other basic tasks which helps working of the d-cam.......................as the computers need processors to handle their calculations, so required by the d-cams.....in this way your d-cam is half computer in which the processor provide functions like image preview, image capture, compression, filter, storage, transfer snd display...............but one imp thing is that u cannot download the pix taken by another camera which will need its own software...............so for different make of cams, different software are used.........not one software will be used for all d-cams. your-own......mine-own system.
THe IMAGE SENSOR.........it is worth noting that the image sensor is the 'film' in a d-cam and it plays such an imp role as their characteristics have a great impact on the quality of your images.............................

D-CAMERA--2
DIgital camera, as u will know, differ in storage capacity. many operate dependent on computer and have no storage capacity of their own. some have in-camera storage only and others have a combination of in-camera storage supported by removal cards. however, in all cases, the photos can be erased whenever required. photos are saved safely in the camera's memory and will not be deleted until u instruct the camera or software. out of these, many cameras are mfd. to be used on location and do not require to be connected to the computer until u wish to download or transmit pictures. the MCU chip is the essential driver of the camera and monitors all tasks taking place in the camera. during power on, the MCU goes out and finds out that all the major camera components are okay. if any major component is not working, a message appears on the LCD and the camera stops working.
IN autofocus (which are generally) cameras when a person presses and holds down the shutter release button half way, the inbuilt 4-bit MPU takes a light reading and obtains the reading that how long the shutter shd remain open and how much light is necessary. the camera opens for the length of time specified by the 4-bit MPU. and for example, the charged-coupled device (CCD) captures light as red, blue and green pixels. the pixels pass thru many of the components in the camera for white balance and colour. the pixels continue on until they get 4 MB frame board. this board puts all the pixel back together in the form of a digital image.

DIGITAL PHOTOGRAPHY FOR U.
SINCE last 10 yeqrs the photography has come under a great change from its inception. the films have turned into DIGITAL sensor, who took the responsibility of photographing images in place of films.. thus DIGITAL CAMERAS came into being. they are little computers that can photograph pix. they are packed-full of computer memory, microchips,micro-processors and a CCD image sensor chip. this camera contains a charge- coupled device(CCD) on which the image is captured. software inside the camera looks at the image three times - ones each for RED,GREEN,& BLUE then combines and presents the complete RGB picture on the screen. CCD is similar to film in a conventional camera. the CCD is used to capture the digital pictures,and pictures are usually stored in Erasable, Programmable Memory microchips.
DIGITAL CAMERAS HAVE SPEED RATINGS THAT ARE SIMILAR in concept to film speed. some cameras operate at a fixed speed and others offer flexibility in speeds to match changing conditions.

intellectualism
In the words of swami chinmayanand: ''the path by which u can realise the Truth is not merely dry intellectualism. if dry intellectualism could realise Truth then all philosophy professors wud be already realised.'' ......... the emotions play an important role in building ways to find out the divine Truth. Truth is not away from intellectualism, but to find out Truth your intellect wud have to take support of the emotions. then the God can be realised. but that is not the ultimate truth. the ultimate truth lies in humanism and the intellectualism may be a part of that humanism which is the basis of this life on this earth. so your brain cannot be intellectual-less, because the ultimate realisation comes through brain. the brain is the pivot point of this humanism, because more powerful is behind the less powerful to make it equal or surpass it. and this is the realisation of Truth, in my view.
