Floundering around

urbanshadow's comments:

It may not be the best shot ever but this is personally my favourite. The shutter speed was very slow due to a lack of light but didn't want to use a high ISO. Due to this and the diver moving around, that made it the most difficult shot I have done so far. I really like the end result and as it was taken form a small submersible it will remain as a unique favourite of mine.
