Do Your Homework
Especially if you are trying to make the transition from taking photos that help you remember things to taking photos that show other people something important, there is no substitute for preparation. Taking the kind of photo that someone else would buy and hang in their home doesn’t just happen. Once in a blue moon there might be a blue moon begging to be photographed. But more often you will need to draw on your own creativity and ingenuity to come up with a great idea. And that means thinking long and hard taking lots of photos and looking over them for inspiration and considering the work of other photographers and artists.
