Hi,
I’ve been working with Photoshop for a long time, and there are three things with transparency I’ve never been able to figure out how to do. Maybe somebody can help me?
The first is: how to make all the pixels in a semi-transparent layer 100% opaque, while preserving their colors. This is different from simply pasting onto a white background, because in that case a 10% opaque red would turn into a light pink, whereas I want it to be 100% red. I suppose that 0% opaque pixels could be come white or black… (Theoretically you could do this by pasting the semi-transparent layer successively 255 times, but this is too much work…)
The second is: how to paste a first image onto a second, but preserving the transparency of the second? In other words, much like "painting with transparency" using the slash key, but copying-and- pasting instead. (Or, alternatively, copying-and-pasting just the transparency values from one layer to another, while preserving the colors).
The third is how to apply "curves" to transparency. For example, suppose I have a gradient that fades from black (0% opaque) to black (100% opaque). Let’s say I want to move the midpoint of that transparency so that it is closer to one end or the other–in effect adjusting the transparency of the semi-transparent parts, but keeping the 0% and 100% transparency sections the same.
Ideally this would be done by converting the transparency values to a black-to-white image, adjusting the curves, and then converting that back into the transparency values… yet I don’t see any way to do this in photoshop.
Can anybody help?
Thanks
Michael
