Is it permissible to draw people using programs like Photoshop, given that they are not permanent like photographs that remain stored on the computer?

Summary of the Answer:

Photoshop is a graphics program used for creating and modifying images. Photographing animate beings without necessity, whether through sculpting, drawing, or computer programs like Photoshop, is forbidden. However, photographing inanimate objects like trees and water is permissible. Those who permitted photography stipulated that the photographer should not interfere with the image by modifying or beautifying it, as this falls under forbidden drawing. Photoshop performs drawing, alteration, and beautification.
