I could not find the word ‘digital’ in Lee Frost’s book - 500 Composition Hints, Tips and Techniques for Photographers. Anywhere … and then it popped up in a chapter on the type of camera you should use. There, the point is made that “it doesn’t matter whether you shoot digitally or expose film, the same rules apply”, then this is followed by the recommendation that it’s a better practice to compose the picture when shooting and not fix it later.
