For every single image I edit, make, I use Adobe Photoshop CS3 Extended.

Photoshop has been described as "an industry standard for graphics professionals."

Photoshop CS3, was released on 16 April 2007. "CS" reflects its integration with other Creative Suite products, and the number "3" represents it as the third version released since Adobe re-branded its products under the CS umbrella. Photoshop CS3 features additions such as the ability to apply non-destructive filters, as well as new selection tools named Quick Selection and Refine Edge that make selection more streamlined. On April 30th, Adobe released Photoshop CS3 Extended, which includes all the same features of Adobe Photoshop CS3 with the addition of capabilities for scientific imaging, 3D, and high end film and video users.

Is it hard to use?
Not really, once you get used to it then you're all good. Patience is needed the most.

Anyway, yeah, I use Adobe Photoshop CS3 Extended.
