Levels or Curves first
in [Photoshop Graphics]

From: Dave on 20 Feb 2007 14:58 Nearly always I do levels first but when doing it other way around it seems to be no different. And I know what's done on levels can be done on curves but I guess most of us do both. Are there a reason to do a specific one first? Dave

Another way to do this, that avoids relying on a histogram, is to use Image>Adjust>Threshold to get assess the brightest and darkest points in the image, and then use curves, skipping the levels step. This has the advantage that you can clip unimportant parts of the image, allowing them to go completely black or white. -- Mike Russell www.curvemeister.com/forum/

Thanks for your reply Mike; and like you said, it seem to be a standard to do levels first. Thanks for telling me about doing it via Threshold -never heard of it, and I'll do my first one right now.

Are there a reason to do > a specific one first? I usually do everything I need to do in Curves. If I'm using Levels, it's because I'm setting the hilight and/or shadow points, which I will do before doing further color correction in Curves, so in such cases I use Levels first, then Curves. -- Photography, kink, polyamory, shareware, and more: all at http://www.xeromag.com/franklin.html

Levels first and set output, then curves. Keep it to 1 levels and 2 curves max, they destroy (clip) information as you can see in the histogram. -- Welcome to Papa Joe's |
