When taking photographs it is always great to have some kind of inspiration from something, maybe something you have a great interest in or something else that gives you the incentive to want to take photographs of that specific thing.
I myself have always been interested in anything to do with nature or the weather, especially autumn scenes with the colours and even wintery scenes with the snow and ice, especially icicles. These are things that we only see around once a year and they never last too long so it's always nice to be able to capture them when they are there so you have them as photo's.
