Something like Chroma Keying in Photoshop

Question

Images

I ask you not to immediately downvote the question, I know how to use the selection, color range and other lasso.
Essence of the question: the designer threw a layout in psd for layout, there is a menu, the active item in which is highlighted like this:

Great, it would seem that you need to copy the layer, save it as png with transparency and put it on the site. But there is one “but”: the “selection” layer has a blending mode of “Screen” (Screen). If we remove this mode (set the blending mode to "Normal") or copy the layer into an empty document, then we see the following picture:

Question: how to save this layer (bitmap on a black background) with a transparent background?Using the "Screen" blend mode, I can put it on any background, but not on a transparent one, in all forums, tutorials on video hosting and other books you can only find descriptions of methods for working with a range of colors, a magic wand and other inappropriate in this case.

Answer 1

Beat the designer with a shovel handle, saying that next time you will tear off his hands for this and sew him to his ass.
There is no easy way to pull overlay:screen for this particular card. Or poke the handles to select overlay: normal (change the overlay layer, unscrew the brightness, colors, etc), or force the designer to redo the same shit, but under overlay: normal.

Answer 2

Get the designer to frame as required, let him row with it.

Answer 3

An interesting problem. I thought “right now I'm soooo…”, but it turned out that in general terms, without the use of manual techniques situationally, the problem cannot be solved in Photoshop. I even found the Screen overlay algorithm , it helped me to emulate it, but did not bring it closer to the result. :)
The main problem is that when Screen is applied, all 3 channels change, and disproportionately, and at the output you need to get, roughly speaking, 1 alpha channel.
In this case, I agree with TheMengzor : shoot the designer and force him to do it humanly, since this is done elementarily if there is a font.

Answer 4

If the designer is no longer available, write in a personal, I'll help you cut it. And if he is at hand, let him cut himself, this is a useful experience for him (or for you, if he explains how) and next time he will think not only about the result of his work, but also about support (cutting, etc.).
