what is encircled exposure for camera?

Question

i got a nice camera, it comes with the function for encircled exposure.... there are some options.. 0.3EV, 0.5EV, 1.EV... how do i choose the correct ones?

Answer 1

The EV setting is for exposure compensation. The default setting is 0 (zero) and this tells the camera to rely completely on its internal light meter.
When you set the EV to a positive value, you're overriding the cameras light meter and telling it to over-expose the shot.
When you set it to a negative value, you telling the camera to under-expose.
The decimals indicate the extent to which you're over/ under exposing. At plus (or minus) one, you're taking the shot with exactly twice (or half) the amount of light that the camera thinks it needs.
Normally, you can just leave the EV on 0 and let the camera do its thing. Cases where you'd want to intervene are for beach scenes or snow landscapes - set the EV to around +1, or generally whenever your subject is significantly brighter or darker than the rest of the shot.
I did a quick search and if you want to learn more, this seems like an easy tutorial: http://www.photoxels.com/tutorial-exposure-compensation.html
