Although additional features or the removal of features may help, for me at least, learning the basics and being knowledgeable of what the histogram is telling me has been the most helpful.
This is what I mean: an experienced photographer is able to look at the frame, glance at the histogram for confirmation of certain things and then take the snapshot with the light, colour and composition in mind, picturing how that would pan out from cradle (preparation) to grave (media).
Not all are masters (I am a “beginner” myself) but my point is that we need to know what the histogram is and isn’t meant for, and within that scope decide what is really a feature and what really isn’t.
I am interested in @ggbutcher adventures; what I am saying is that they won’t blow your mind, except to help you appreciate what the histogram is.
