I was impressed with Alex's picture of Ghiannis D. and I thought it would be a good excersise to try and copy it. Unfortunately our dive guide was a bit disorganized and I ended up taking the filter to a dive at Carnatic instead. Moreover the dive got delayed until late afternoon and it got cloudy.

Suprise! What I saw at my LCD was actually way better than what I was able to see with my bare eyes.
