Johnnyallen Posted December 11, 2017 Share Posted December 11, 2017 Can someone give me a good link to a tutorial about Histograms. I have a good one for Curves and understand what's going on, but the input/output in Histograms has me a little confused. I can, of course, see the effects, but a discussion on which is better would be helpful. Quote Link to comment Share on other sites More sharing options...
toe_head2001 Posted December 11, 2017 Share Posted December 11, 2017 Are looking for a technical explanation, or just a simple guide on how to use it?

Johnnyallen Posted December 11, 2017 Author Share Posted December 11, 2017 The simple guide looks pretty good. For now, I'll peruse it. Thanks for the quick reply. Quote Link to comment Share on other sites More sharing options...

Johnnyallen Posted December 12, 2017 Author Share Posted December 12, 2017 (edited) The PDF was very helpful. So was the simple guide that toe_heaad2001 offered. FYI my experience in TV production and editing has added to my knowledge of primary and secondary (complementary) color. A TV control room wouldn't be complete without a waveform and vector scope. I understand very well what I'm looking at when I open levels and see the graph. The higher the curve the more pixels have recorded that color in that point in the scale from black to white (grey scale, which by the way, we use to use a lot in TV). What I needed was an explanation of what the other stuff was, numbers etc. What they call dialog. I previously was processing RAW with curves, but now knowing more of Levels, I find that I have better and more precise control of color and contrast. I also added a plugin for white balance and other effects. My Nikon does a pretty good job with Auto White Balance, though. Thanks again for your help.
