Teach Yourself Photoshop - 13th Edition, 2023

The photographic process starts the moment you press the camera’s shutter release button, but it doesn’t end there. Sometimes the camera makes a mistake, you compose the picture in a rush or an unwanted object needs to be cloned out, and you need the help of an image-editing program to put things right.

The camera also captures the world in a very literal way, so that the image you see on your computer screen can look like a rather pale imitation of what you saw in your mind’s eye. This is where you need a really good image-editing program, and Photoshop is the best there is.
