Going beyond the literal
Beginners often photograph their subjects literally. There’s nothing wrong with that. Many times, though, an ordinary subject can be made extraordinary. That is rarely due to the subject and almost always a reflection of the photographer. Extraordinary photographers do not see their subjects only literally…
Begin to look at your compositions as visual elements, rather than merely literal subjects, you will go a long way towards taking photographs to be proud of. Remembering that photographic images are made of tone, shapes, and lines and their relationships will make it easier for you to find a good composition, no matter what the subject. And you’ll know that even old subjects can be shot anew, no matter who tells you differently.
