Color dodge is not working on photoshop 2020

[makafello1103]

I was using cs6 and i upgraded my mac to Catalina and nothing is compatible so I have to move forward to photoshop 2020 and i opened a project who has groups with color dodge on it and is not working, looks like painted with white color and not as brilliant colors, please help

What exact version of Photoshop (go to Help >System info)?

I've just tested with v21.2 and Color Dodge looks to be working correctly on both layers and groups here.

this is what i got... Adobe Photoshop Version: 21.2.0 20200604.r.225 2020/06/04: 02a81f3015 x64

Yes it appears broken if we are to believe photoshop versions 6 thru cs6 are right and most version of photoshop cc (2017 thru 2020) are broken.

ps6

cs6

21.2.0

There are several ways around the issue depending on what layer the color dodge is on.

If the Group itself is set Color Dodge then go to Layer>Layer Style>Blending Options, uncheck Transparency Shapes Layer and set the Fill Opacity to 99

Actually it looks like the colour dodge brush is incorrect and that a previous error on layers vs groups has been corrected

Colour dodge is defined as Blend  =  Background / (1-Foreground) ) unless background is black in which case Blend = 0

So that should look exactly the same as inverting the Forground colour Fi = (1-F)  then using Divide blending mode B/Fi

I used 50% grey for the background and 75% brightness for the foreground (or brush)

The left pair (normal should be the same and they are) The right three pairs should all look the same - they do not. The exception is the color dodge brush.
