The Bucket Test
visualize what a camera light meter is doing and how you can get around it. I'm going to use five buckets on my right is a black bucket, and on my left, I have a white bucket in between, like gray, medium gray and dark. Right now, I want you to imagine that each bucket is one stop lighter or darker than the bucket next to it. So, like gray is one stop light of the medium grey on one stop darker than white. Now, for this trick, I'm going to get a white rabbit. Probably not a real white rabbit, because, well, I'm a wildlife photographer and there are ethics involved because the rabbit is white, toe it correctly expose it. You would praise it in the white bucket, but the camera doesn't see. It is white, the camera thinks is mid grey and so puts it into the mid grade bucket instead. Ondas, if by magic turns, are white rabbit gray. Now, to make the rabbit white again, you have to reverse the magic to get from white to mid grey, the camera has under exposed by two stops 12 so you have to do ...
the opposite you set plus two exposure compensation plus one plus two and hey, presto. In our white bucket, we find a white rabbit. Now a similar thing happens with a black rabbit. To correctly expose a black rabbit, you would place it in the black bucket, but again, the camera doesn't see black as black. It sees it doesn't medium grey, and so it puts it into the medium grey bucket on wall are. Once again we get a medium gray rabbit. Turn the rabbit back to black. Once again, you have to reverse the magic they get from black to mid grey, the camera has over exposed by two stops 12 So again, you have to do the opposite. This time you set minus two exposure compensation miners one minus two. And in our black bucket, we find a black rabbit by thinking in these terms, using exposure compensation to tell the camera which bucket the subject should be in is easy to get a technically accurate exposure in any lighting on whatever the subject,
