Photoshop is considered one of the most important programs for editing images that any artist needs to learn and master. Understanding how the program works makes it easy to learn any modification program quickly. We provide an overview of Photoshop tools as well as some exercises and the best ways to learn Photoshop individually without the need for a teacher. In other words, after two or three lessons at most, you will be able to start your own and unique path to mastering Photoshop.

We provide a detailed explanation according to the student’s desire and need for one of the prescribed classes in mathematics.
