Photoshop Guide

I am new user of Photoshop. I want to learn it for photo editing. If Photoshop users are here on this website then please tell me the latest version of Photoshop. Also tell me website where I can download it free.
what is the meaning of cs in Photoshop… i.e. CS3, CS6

I believe CS stands for Creative Suite, which is a range of software to which Photoshop belongs. The latest version seems to be Photoshop CC, which stands for Creative Cloud.

Photoshop is not a free software, but you can download a free trial version from Adobe. After that, if you like it and want to keep using it, I’m afraid you’ll need to pay for it.
