There is thousand and one way to enhance your creativity and better your photography. It seems as if everything has been done before and that might be entirely true. But there is always something coming up either with an old idea in a new dress or some new angle, new technical possibility or an ingenious idea.
Be it old news or new ideas - try out whatever you come up with photography to get a better grasp how to do it, what to use, what gear and last but not least implement inspiration from other arts as well.
And most of all - have fun!
