P: Issue with Vivid Light. Possible bug or intentional?

[Deif Lou]

Hello everybody.

I was playing with some gradient outer glow and noticed that the "vivid light" seems to misbehave for some range of colors. The specific range depends on the colors of both the source layer and the layer below. But I'm not sure if that is intentional. I think it is a bug because this only happens when the fill opacity (for normal layers), or opacity (for layer effects) is set to 100%. If I change that value to 99% or less, then the blend mode seems to work as expected.

If I'm not mistaken, the "vivid light" blend mode should use "color burn" to blend the color components if the source value is less than 1/2, or "color dodge" otherwise. So it seems as if the bad colors happen where the "color dodge" should be applied. At least when I change the opacity to 99% it seems that those areas look more like if the "color dodge" blend mode were applied.

Also if one changes to "hard mix" which is like an extreme version of "vivid light" it can be seen that those regions are rendered the same at 99% and 100% fill/opacity, and look similar to an extreme version of the 99% fill/opacity "vivid light".

System Information

System: Windows 10 virtualized with VirtualBox Versión 7.0.4 r154605

Photoshop version: 24.1.0

Steps to reproduce

1. Open the attached file.

2. Change the fill opacity of "layer 1" or the opacity of the "outer glow" effect in "layer 2" between 100% and 99%.

3. Notice the difference is too drastic.

Extected result

When the "vivid light" blend mode is used with 100% fill/opacity (depending on wheter the source is a layer or a layer effect), the result should look similar to when the fill/opacity is 99%, with no such a drastic change.

Thank you @Deif Lou for the excellent write up and STR and video. I was not able to see any noticable difference using layer 1, but was able to see what you do using layer 2.

It may help if we could see your Photoshop System Info. Launch Photoshop, and select Help >System Info...and copy/paste the text in a reply.  

Thanks again,

Cory

Hi.

For the "layer 1" case keep in mind that I have to change the fill opacity to see the issue. If I use the opacity then the colors don't seem to change.

Here it is the system info. The Windows 10 is virtualized using VirtualBox, since my main OS is linux:

Another simple way to reproduce the issue with a normal layer:

1. Create a new document.

2. Fill the background with a rainbow gradient.

2. Create a new layer and paint a black circle on the center.

3. Apply some blur to that new layer.

4. Set the layer blending mode to "vivid light".

Observed result:

The blended layer shows some weird hard edges when the fill opacity of the layer is 100%. It works fine if the fill opacity is lowered.

Expected result:

Since the color of the painted circle is black, the blended layer should look like when the "color burn" blending mode is applied. That is true when the fill opacity is less than 100% but not otherwise.

[Jeff Arola]

Bug or not, the behavior seems to have been around since photoshop 7 when the Vivid Light blending mode was first added to photoshop.

Another similar Fill Opacity issue that still has yet to be addressed:
