The… [Read More]

In the previous post, we saw that, with standard settings the D4 shows minor clipping in its true raw histogram at the metered exposure for a moderate contrast subject, even though the in-camera histogram looks clipped at that exposure. In this post, I will show what happens when you find the correct ETTR exposure by… [Read More]
