Photoshop: How do I paint with consistent opacity?

When applying a change with a brush on low opacity I know that if I release the mouse and start again the opacity doubles.

However this creates a problem when a large area is being covered and the changes are slight and delicate. Sometimes it's hard to see where you left off and relocating the mouse with another click creates overlaps that are not wanted.

Is there any way to lock the opacity so that I can brush freely without worrying about unwanted overlap? If not, this is a feature I would like to see. Especially if it had a hot key like holding the alt key to activate etc.

If I understand what you're asking, the easiest way to do that is to create a new layer and paint on that, and reduce the opacity of the layer.

Hi Chris. thanks for the reply but that is not what I'm asking. I do it that way now. The problem is that one cannot always apply a brushed change in one stroke and occasionally needs to reset the mouse.

But doing that doubles the opacity where the strokes overlap and creates an unwanted area. What's confusing is my choice of words concerning "locked opacity" I didn't really know what to call it. I know the opacity is the same when I restart after a mouse click but want some way to not have the doubling effect when it overlaps.

Well, what you're asking for seems to be the same as creating a new layer. There's no other good way to do it (even with changes to the code).

Creating a now layer won't solve the problem because you'd still have to mask the overlayed area. It would have to be a code change and that could be done by sampling the last change made with the brush and internally masking that area when a new application of the brush was applied.

Is there a procedure for asking for code changes in future upgrades?

No, you don't have to mask anything. Just paint at 100% into the layer, and change the layer opacity.

What you are asking can't be done easily with code changes -- pixels only have one color and one opacity value. Trying to keep the last brush tip application mask isn't even possible in all cases.

Requesting a feature here is the procedure. And an engineer has just told you that this makes no sense as a code change, and can already be accomplished easily with a new layer.

Thanks Chris. I never thought of applying 100% and then lowering the opacity, and then applying another layer after that. That would indeed do the job. Thanks so much for sticking with me on this. Cheers.
