PHOTOGRAPHY--ARTIFICIAL LIGHT--3

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).
