Why can't I invert anything? Or DO alot of things.

Hello, I've come across something, it's that I can't use A Lot of features Photoshop offers me, in this case, doesn't offer, just teases (puts majority of options in grey - not usable). So I come to ask, why can't I? I even enabled the 7 day trial, because I thought it's just a premium trial, and it will fix it but it didn't.

Now I'll try to post an imgur of ss I took. (To mention, in the following picture, the selected layer is Not locked.)

I'd appreciate any info.

It looks like you are in 32 bit/channel mode. Switch to 16-bit and those menu items should become available

Thank you a lot!

Can you tell me what's the difference, why can't I do it with higher bit channel?

32 bit is really designed for specialist use.  Unlike 8 and 16 bit which limit the range from black to white to displayable values , 32 bit extends black and white well beyond what can be displayed. That is why it can be is useful as an interim in HDR imaging or when creating a 3D scene.

16 bit is sufficient for ordinary image creation

JPGs can only be saved in 8 Bits/Channel
