Classic Color Burn

[Steven Kutny]

Thanks David,

I read this earlier and found it interesting. By definition, it seems that this is just a random legacy thing that Adobe decided to keep all these years. If they could give us a way to recreate the effect inside Photoshop, I’m sure I could figure out a flame translation. Thanks for the response.

hmm I’m a little stumped, the formulas are the same. I’ll get back to you, I believe you have to go back farther into an older reference. I’ll see if the formula changes

Wow! Thanks for all the input guys. I’m pretty sure that this is one of the most confusing things I’ve ever tried to find in Adobe documentation! I’m still trying to figure this out. I don’t see a “7.2.4” in any of the 3 current downloadable documents from the Adobe site. Chris, thanks for your link but is this version 1.7? It’s dated from 2006 and doesn’t seem to cover the “classic color burn.”

I’m as confused as you are. All the documentation to classic color burn has been deleted. I checked every reference and even going all the way back to 1.3, the stuff is gone.
But if you are smart with math, you can derive the classic burn by

“color burn retains the shadow whereas the shadows disappear with classic color burn.” so the formula is almost exactly the same, just the blacks get ignored.

7.2 is the chapter in the index pdf btw
