LIGHT METER-AUTO-LOCK

THE CAMERA COMPANIES HAVE GIVEN SEVERAL FACILITIES IN THEIT DIGITAL CAMERAS...IF U VIEW AND READ, IT BECOMES A GOOD COURSE BOOK.

To read the light,it is necessary to incorporate a device which will calculate and suggest u about the use of shutter speed, aperture and important is ISO. Besides many metering facilities, they have provided a feature called ''autolock''..Therefore while directing ur camera on a subject, u have to put your choice of exposure on the Cameras's main dial. Keeping it on auto will solve most of your problems. The flash will automatically pop-up, if the light is low. If there is sufficient light the camera will calculate its exosure on auto basis and if ur eyes move to another subjects in between, u can focus on the main subject and the button generally fixed near the viewfinder can be pressed half way so the focus is locked. now by pressing the AEL button, u can move camera to other subjects and if need be, do the same exercise and per chance u have not shot or selected any other subject, bring back the camera to the first subject where u locked the focus. Now u are ready to shoot, click the release button.

In the photograph shown, i focused on the centre small leaf and half pressed the button moved to see something worthwhile, i came back to the leaf and clicked.
