Make your old images new again by recomposing and cropping.
One of the gifts of digital photography is being able to edit and continuously change original captures. I've found that shifting the perspective of the viewer by recomposing an image in post processing is a great way to spark new life into what might be an uninteresting image. In totality some pictures might be okay. But by recomposing an image you get to view it in an entirely new way.
Depending on the results, a basic image can take on a completely different mood. A poorly composed shot might be reframed into a great shot in post-production. Take the following image; a gorgeous woman and a fair picture. However, by changing the point of focus you gain a completely different perspective by zooming and magnifying different areas. In the recompose on the right, you focus more on her gorgeous facial features and transform a basic image into what might be considered a beauty
Before you throw it out reconsider the advantage of recomposing an image. However, make certain that your image can withstand the resize. This depends on several factors; resolution, resampling, object type, clarity, and exposure being chief among them.
Most importantly, be certain that your are within your rights to modify, edit, or manipulate the image. Just because it's you doesn't mean you have the right to edit it. This depends largely on copyright ownership and usage rights often between the photographer and the subject. It being in your possession doesn't necessarily make it yours. In fact, in most cases it isn't the subject photo in the strictest sense of copyright ownership so be careful.
If you're the photographer then you probably know based on your model release or some other agreement. In any event, it's a great way to make something new from something old.
