"Reverse" and image in Photoshop?

I have a PSD image from a client that I want to reverese, like if you printed a film negative backwards. I cannot for the life of me figure out how to reverse an image in Photoshop. Any suggestions?




if thats what you mean. It’s inverted. By reverse you mean…? Haven’t paid attention to negative film, is it all opposite like a mirror reflection? WOrk with Image > Rotate Canvas > Flip Horizontal

*CTRL + I will work for the active layer

You may get a yellow cast through your image from the actual film, to correct this adjuct your channels.

Thanks guys!..
