I like free diving with monofin and, some time, I use the camera. I took this pic in Sardinia, close to Pedralonga beach (Arbatax). The sea in July was quite clear but not so warm (3 mm wet suit is necessary for free diving, I used just a body...). I like to relax lying on the seabed and create bubbles like this with one breath (good exercise to improve the apnea), why not to take a pic? This is the result.
