Now discussing the auto focus and auto exposure lock (AE/AF) a bit more in detail. The shutter
release button on a digital camera has more function than just snap a cool picture. The users have
to grab a technique where he or she has to depress this shutter release button half way down
thereby locking both the auto exposure and auto focus. This enables the users or photographers to
have more control on exposure in difficult lighting situations while using the digital camera.
Moreover, this entire process also helps him or her to determine where the camera focuses. Like if
the photographer intends to set the exposure before composing the final shot of the photograph
then he or she can move the digital camera slightly so that only the subject to be photographed is
visible prominently in the auto focus frame in the viewfinder. As a next step he or she can depress
the shutter-release button down half way to set focus and exposure and then recompose the
picture and finally completely depress the button in order to capture and freeze the moment of
time! It is to be noted here that the auto focus and auto exposure lock (AE/AF) is available in all
photography modes of the digital cameras that are nowadays available for the general people.
Not much remains to be discussed about this particular topic of auto focus/auto exposure and a
brief discussion as above is enough to reveal a bounty of information regarding this fantastic
feature of the digital cameras. At the end of this discussion it can be expected that both the novice
and expert photographers and user of the digital camera would benefit from whatever has been
revealed and the effort to bring out the human mind from the dark oblivion about auto focus and
auto exposure lock would be a success in the magic light of the digital camera!
