Images many won't even try are not difficult. Read the picture taking directions in most books, manuals and film boxes. Keeps lens flare down and the subject squinting. It can give excellent results if you are adept at judging light or are just lucky. But don't plan on getting good results with luck very often.
Good results are the result of luck backed by effort and ongoing learning.
A few basics will improve your efforts shooting into the sun quickly. First, a lens that doesn't flare too much is a big help. Shoot into the sun and test the lens. I test them first by going outside and shooting a roll of slide film directly into the sun. First wide open then at at a middle stop and finally stopped all the way down.
