Nice to meet you too! uh? oh! no, I don't need help with CSP, I have a good grasp of the software. Let me clarify, my question is about color depth.
When you create a document in photoshop in RGB you choose if the color depth of the file is 8, 16 or 32 bits. However you can't choose that in CSP, according to the online instruction manual is always in 32 bits. The tricky thing with CSP is that you can open and save PSD files as long the color depth of such files are 8 bits. So this might create compatibility issues if the work requires a higher color depth.
My question was intended to know in which cases a higher color depth is required, the search in google show me that this is used mainly in photography to make subtle editing or something like that, but then Marc barely talked about this in the photoshop class, giving an example about a pattern being compressed to be used in a videogame. So I was curious about how common and in which cases for digital art this higher color depth setting are used.
