I have not found a way to do so. Is there a tool or method?
If not, I'd like to suggest Adobe add this capability as it should be fairly easy to implement in code.
1) Duplicate the layer with the Blend If
2) Create a new empty layer under the duplicated layer with the Blend If
3) Merge the empty layer and the layer with the Blend If
4) Select the layer you want the mask to go to
5) Drag the resulting layer from Step 3 to the new layer mask.
Of course you could create an action or script to do it in one click.
Now off to create a .atn
Only change I made for my purposes...in step 5 rather than drag, ctrl+LMB click and save mask to channel for future uses.
Thanks so much for such a simple solution. I hope others see this for their own uses. I shared with 2 other forums but not within Ps general.
JT, Your reply was great and I have .atn and use it when needed.
Now I have a similar question and hope you have the answer for this:
If I use a Hue-Sat adj layer and make a color selection range and adjust the range and fall-off (which I can see on screen to get it as desired, and apply), can I somehow create a layer mask of the area affected? How would I do so?
This would be a different way to make a mask, based on color selection.
Or perhaps a different tool could create the same mask (color selection) as done with Hue-Sat tool? How could I do that?
End goal is to have another, optional, choice for color selection to make a mask to use in another layer correction. Often the color selection tool or a mask based on color/luminosity is inadequate but the Hue-Sat tool is excellent, but it does not seem to create a mask that could be used elsewhere.
