1. Re: Sample true color from layer less than 100% opacity
Are you using "Sample current layer only?"

2. Re: Sample true color from layer less than 100% opacity
Thank you my friend.
No, it's set to "all layers".
The problem is that the photograph layer on top is at 25% opacity, so it samples the color at 25% opacity- which ends up being a de-saturated, dull color.
I was hoping to find a way to sample the *true* color from that layer, regardless of its opacity level, without having to manually change its opacity to 100%, sample the color, then change the opacity back to 25%.

Only way I know is to use sample current layer and select that layer to take a sample.

4. Re: Sample true color from layer less than 100% opacity
thanks. I'm using the top layer (layer with the original photograph) as the original sample reference. I want to drop the opacity to 25%, so it can be used as a "tracing paper". Then with the new layer underneath, I'll sketch/paint(trace) the image. I want to sample the true colors from the photo on the layer above, but not at the 25% opacity it is displaying. I need to sample the color from that layer at its *true* 100% opacity color.
I know the mixer brush can do this. So load the photo on the top layer, then drop it to 25% opacity. Next, create a blank layer under it. Next, choose the mixer brush tool and choose a brush to your liking, and make sure "sample all layers" is turned on. Make sure to turn OFF the "load" icon in the mixer brush well, and to turn ON the "Clean" icon in the mixer brush well.
Now, on the blank layer underneath, begin painting. It will sample the colors from the photo layer ontop, and it does so as if the top layer was at 100% opacity even though it's at 25%
This is what I'm looking to do - but with the brush tool instead of the mixer tool.

Yea, I understand. There was a post a while back regarding this with the OP wanting to do the same thing. I just don't know of any other way of doing it.

6. Re: Sample true color from layer less than 100% opacity
dang. Oh well. I'm pretty sure it can be done with scripting... I'll try it. So in other words, every time you hold down ALT, it will temporarily change the above layer's opacity to 100% while it samples a color- and then when you let go of ALT, it will return the top layer's opacity to 25% and you can begin painting again on the layer below, having successfully sampled a color from the layer above at full opacity.
The reason for this is fast workflow. Selecting the layer above, changing its opacity, then re-selecting the layer below to paint is a workflow kill, in the worst way. It's not practical.
I'll report back if I can find a way to do this.

A quick workaround if you have the screen space is to duplicate the image (Image -Duplicate) then go to Window-Arrange and Tile 2 up vertical. You now have both the working image and a duplicate along-side each other . You can set your top layer to 100% in the duplicate. Then with the brush selected in the working image you can Alt click on the duplicate to sample and paint with that colour on the working version.
Bit of a workaround but much quicker than changing layers for every sample

There might be some some workarounds with scripting; however, it's not possible to get the cursor position with extendscript. So writing a script to get the position and sample the color would not work. Best I can think of is to create a script to set the opacity of the layer above the active layer to 100%, and another one to set it back. You could then assign the two scripts to a hot key to press quickly. You would need to record the layer's opacity value and store it somewhere - perhaps it the file's metadata or to the clipboard.
