Heres one that might help. I found it really useful.

Michael Reichmann's always a good source for information, here's another link you might find useful:

abh1, that article is not only good, but humorous, as well.

I guess I should also think about reading my software manual, duh!

nah, software manuals only come in the box to keep the cd case from flopping around :/

Nah, I wouldn't do that. ;-) You'll probably learn more by just experimenting. Hopefully the links you've looked at will give you a start. Good luck.

The guy who taught me desktop publishing always said "don't read the manual -- you'll just get confused."

The most important principle to remember when using Curves is that areas of the photo which have pixels whose value falls on the steeper part of the slope will show greater detail. Areas with values on the more level part of the tone curve will lose detail.

You can also use curves as a means of selectively modifying certain colors, or of completely changing the color scheme For two extreme examples, see my photos "Golden Gate" and "No Visible Means of Support" which were "colorized" using duotone curves and regular tone curves respectively.

Hmmm, and I've been doing it by modifying my caloric intake...

i've taken some classes in Photoshop and i've done a lot of trial and error stuff...and, i have to say, with regard to the Curves function...trial and error is the most fun. you'll be amazed at the results you can get from just playing around with it.

anyway...that's my opinion. :)

I don't know about that. That's a little out of hand. Maybe if you're coming from another software package and know the functions. But for someone that hasn't a clue of what the application can do, will do for them or how to use it. The manual is the first place to start. Yes, there is nothing that will substitute practice and just doing. But with no clue as to what you're doing, it isn't going to help much.

I've never used the Curves fonction.. I've always used the Levels fonction instead. Is there such a big difference?

Well that was really my friend Tony's advice. He was giving me a hard time because of my habit, whenever new software arrived, of taking the manual home and reading it through quickly without using a computer. I generally knew which functions I'd need, and would read those sections more closely...and then when problems came up with the program, I'd generally remember what part of the manual (if any) dealt with it. Also, these were 1980s and 90s manuals -- renowned as a genre for their obfuscatory explanations and syntactic ineptitude...
