new on the photog forum but this question really bugs me. So the situation in which I was shooting: Dark night with some bright "light" art. Person stood in front of the art and I took the photo. Obviously the person is underexposed and I know that I should have a flash and use flash comp (or maybe even a flashlight). This is a dynamic range problem I know but when I'm auto focusing I notice something very odd.
Pretty much what happens is when the auto focus is trying to focus, I can see the exposure is perfect. The person is lit well and so is the art. It reminds me of how smartphone photos get exposed where you can see everything and nothing is under/overexposed where it's not meant to be. But once the camera is done focusing, the subject is very underexposed but the light art is exposed correctly (as expected).
This occurs often when the scene's dynamic range exceeds that of the camera but this night it was especially frustrating.
So I was wondering if I'd be able to get that correct exposure that the camera has before it finds its focus. I was thinking it might be since in my EVF I get a read off the sensor. This would eliminate the need for flash/torches/HDR etc. but I've done some fiddling and not been able to do it.
