How To Master Color Adjustment With Curves

Curves does what other color adjustment tools can’t, precisely adjusting two out of three elements of color (luminosity and hue but not saturation) based on lightness. No other color adjustment tool is as powerful or precise as Curves. Surprisingly, many people don’t use Curves because they find its interface confusing. Yet it’s that interface which offers so much control. You can master Curves quickly and easily with this guide. You’ll be thrilled when you do.


Why Use Curves ?

Curves gives you the most precise control of luminosity. This applies to the whole image and to select areas of an image. This can also be extended to adjusting hue by luminance values.
Curves will help you control and refine masks.

Curves will simplify your Photoshop toolset; you’ll need only a few other color adjustment tools.
You can do more with this one tool than you can with any other.

If you asked me to throw away all of the tools in Photoshop or Camera Raw and use only one tool it would be Curves. It’s that good. It’s that important. I strongly recommend that you not only learn to use Curves but that you master it.

      Hi Andre,
      I see you as a member with a email. Try that and the password free. Perhaps try this after clearing your cache. Clearly you’re not the only one who’s having trouble and equally many are not. Meanwhile, I’ll look into this further.

    JP – that was a great article and even better, all the tips and tricks in one place! As an engineer I’m very comfortable with “curves” but don’t do well explaining it with X-Y axis commentary. When I say the bottom line is “before adjustment” and the vertical axis is “after adjustment” people seem to get the idea much better.

    I cannot read the full article. John, Whomever manages your website does a horrible job. Too many broken links. Sorry to seem negative, but you should be aware of this.

          That helps. I’ve forwarded your response to my web developer and asked him to look into this.

    Great tutorial! Thank you for demystifying “Curves”. I use Capture One as my primary editor (and PS for the few edits it still does better than Cap1) but it was easy to translate your descriptions to the Capture One Curves UI. Now I’ll be doing more than just applying the typical S-shaped curve in my editing process. 🙂
