Bild in Bittiefe 64 speichern [GERMAN]

[Kpri]

Hallo,

ich habe eine Frage zu der Bittiefe in Photoshop. Ich benötige ein Bild das in der Bittiefe 64 gespeichert ist (png). Das Problem ist jedoch, dass mein Photoshop diese nur in Bittiefe 32 speichert. Ich habe Photoshop 2020, sowie Elements auf einem x64 Windows-System laufen. Gibt es eine Möglichkeit ein Bild mit Photoshop so zu speichern oder muss ich dafür ein anderes Programm nutzen?

Vielen Dank!

Photoshop can't save an image in 64 bit depth. From looking at the web, there are some programs that can convert images to 64 bit. But why do you need to do this?

Thank you for your answer!

Oh really, that's too bad. What programs would that be? I didn't find any, but maybe I used the wrong terms for the search. I'm working with the Unreal Engine and for implementation of functions like a compass, the program needs a 64 bit picture.

The largest bit depth supported by PNG is 16 bits per component - 48 bits for RGB, 64 bits with alpha. Photoshop goes up to 32 bits per component - 96 bits for RGB, so it is much more capable than your needs.

Thank you!

Oh maybe we get closer to the matter, I think I might need an alpha. But how can I create one?

Alpha is given as transparency in Photoshop. So far as I know, you just delete your layer called Background and create an image with transparent areas in a new layer (or layers). Save as PNG (do NOT use Export or Save For Web). Don't worry about the "alpha channel" setting, doesn't seem to be what you need.
