Requesting a tutorial on how to mirror LAYERS in photoshop, like in gimp. I just got photoshop and tried to mirror a layer but when i do, all my layers get mirrored like as if they were linked together or locked, but they aren't, ovbiously....

So, in gimp i go like Duplicate layer>Transform>Flip Horizontally

In photoshop i try the same, but it doesn't work...
