Histogram vs Curves

[Johnnyallen]

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.

Are looking for a technical explanation, or just a simple guide on how to use it?

[Johnnyallen]

The simple guide looks pretty good. For now, I'll peruse it. Thanks for the quick reply.

Levels - A How to and Basic Understanding (Now a PDF!) (use the second link in the first post).

[Johnnyallen]

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.
