Photoshop CC is an advanced imaging software used by designers, web professionals, video editors, and photographers to alter or manipulate digital images. Photoshop is primarily used to edit 2D images, although it does offer some 3D image editing functionality. It's worth it, I've been using CC for many years, and it's just easy do download, and check others apps available in Creative Cloud (since the membership give you access to some of the most important Adobe's Apps like Illustrator, Photoshop, Premiere, After Effects, and others).
