A few people have questioned why I’m going to all this trouble to find out how to approximate the real raw histogram. Why not just accept the extra safety margin that the camera gives with a normal JPEG preview image? I dealt with some of that here. Here’s a salient excerpt: …if a full frame… [Read More]
