hi there,

i’m quite experienced with photoshop, but i never found a solution for this problem, maybe someone can help me:

if you have a layer with transparent pixels (done to eraser-use or because you used a mask), how can you reduce this transparency again. is there a way to edit the transparency chanel of a layer? i can’t believe that photoshop hasn’t such a function, but i never found something about. in my imagination there should be a mode where you can edit the transparency with the normal painting tools, the curves and, and, and.

thanks for any hints.

You can’t.

If you’ve used the eraser, the pixels "behind" the transparency are GONE. You can’t bring them back, and you can’t directly edit the transparency any longer. By using the eraser, you have removed the pixels from the image.

If you want to be able to do this, never, ever erase or delete anything from a layer. Use a layer mask instead.

They may be gone if they are 100% erased, but not if less. Then there colours stay untouched. You can see that in the colour-info-box, which you also can switch to measure the opacity/transparency.

In my case i made a colour-range selection and copied it to a new layer. As this selection has no sharp edges and the pixels are "selected more or less" – 0-100% … in the new layer there are regions with variating transparency. If i could readjust this, things would be easier. I know I could work with a layermask instead of copying the selection to a new layer. I’ll do it the next time, now I’m nearly done. Anyway I think it’s strange, if there is no possibility to rise the opacity of a pixel, but only to reduce it.

bye,
johannes.

try duplicating the layer it will increase the opacity
