The Russian photography specialist, Elena Kalis, (we mentioned once here), spends most time in water and with her camera to shoot the planned and spontaneous photos underwater. She likes how different things and people look underwater, movements are graceful and free and it has a dreamlike quality that is difficult to achieve on land.

Technically and skillfully, she shot with Cannon 5D Mark II, 24,28,50mm Canon lens with red underwater color correction filter. She also used snorkel, scuba and compressor.

Normally, she did not use strobes while she was taking these photos but she was shooting on sunny days and near water surface or ocean.
