This has probably been said many times before, and in many cases it's true...change your perspective to capture a unique subject or lighting situation, and your photography will improve.  We tend to look at everything from a standing or sitting position, which is perfect most of the time, but every once in a while changing your camera's perspective gives your photograph something different for the viewer and is so much more interesting.

This technique requires much trial and error since you can't actually see what the camera is capturing, but it's fun to guess where the focus will be and click away! 

Purple Haze When the light is right, this technique can be very effective and pleasing to the eye.  But be prepared to have many captures that are throwaways, since it truly is a hit or miss scenario.  The other advantage to this technique is that you can capture some amazing natural features that only small animals and bugs usually see!  Try holding your camera at different levels next time to see what great results you can get.
