I'd like to bake hue and saturation information directly into an image. This is my current setup that gives desired color values:

enter image description here

If I merge group into a single layer I lose all the information provided in Hue/Saturation

enter image description here

What should I do to maintain the color information in the highlight when I merge group?

Anytime merge group, layers or flatten operation is done without the black background enabled (Layer 8), the newly merged/flattened image loses hue color information. If the black bakcground is enabled, color is preserved.

Merging With black bacground is successful Merging With black bacground

Merging with transparent background. Hue color information is lost. enter image description here

My goal is to come up with transparent image of phone case and highlight, so I can overlay it on top.

Simply Flatten the image - Layer Panel Menu > Flatten image.

Another option is to Merge Visible -- Create a new blank layer above everything, and highlight it, choose Merge Visible form the layer panel menu. This will basically flatten the image while not creating a "background" layer.

What I generally use...

If you wish to keep layers in tact and merge, hold down the Option/Alt key when you select Merge Visible. This will combine all visible layers to your new blank layer and keep other layers as they are.

All layers visible except the white screen.... I created a new layer... merged visible (with Option held down), and then copied the layer mask to the new layer.

Merging Visible of only the frame art and adjustments...

  • Thanks for stopping by. Unfortunately, none of the suggestions preserve the color in the highlight. Anytime I merge, flatten layers without the black background layer at the bottom enabled, I lose the color information. If I enable the black background layer, and then perform the merge or flatten, color is preserved. Unfortunately I need a transparent image. Commented Mar 29, 2019 at 16:00
  • I think this might something to do with hue and saturation being an adjustment layer Commented Mar 29, 2019 at 16:09
  • Merge visible should merge layers to exactly what you see. I'm afraid if that's not working it may take direct file examination, which would be kind of off topic. I've never seen merge visible fail.. with or without adjustment layers in play.

  • Take a look: ufile.io/0x2li. I think hue and saturation has some unexpected behaviour when operated on semi transparent pixels. On black bakcground, of look great, on white.. hue information is lost Commented Mar 29, 2019 at 16:48
  • See updated answer @arraysareslow It seems to work as I expect. Are you trying to eliminate the black? That'll never work. There has to be some hue/saturation present for any adjustment to those to work.

  1. set the visibility on only for layers you want to merge. Hide all others
  2. Press Ctrl + Alt + Shift + E
  3. Voila !

Edit: Command + Option + E (Mac)
