Last month I went for a few days to the Silfra crack at the Þingvellir national park for snorkeling and underwater photography. The special feature of Silfra is it’s visibility range underwater of up to 130 m. The Silfra water is probably the clearest in the world. The water is coming from some big highland glaciers but runs for 30 to 100 years through the lava before entering Silfra. Therefore it is extremely filtered. The underwater experience in Silfra is absolutely incomparable to anything else in the world and should not be missed.
The only problem with snorkeling or diving in Silfra is, that the water temperature is around 2°C, in summer and winter, which is not very warm. On the first day I joined an organized tour with DIVE.IS where some rental dry suits were provided. On the next days I was using my own 8mm neoprene wet suit, which worked better than expected. My body, head and feet always stayed warm, but I made a big mistake regarding the gloves. I thought for a good handling of the underwater housing thin gloves are helpful. But at 2°C water temperature you definitely need the thickest gloves available. After 30 minutes in the water with 2 mm gloves I could hardly move my fingers.
I have some experience in landscape photography but it was only my second attempt in underwater photography (after shooting a few days on the Maldives with a compact camera). Therefore it was also the first real test of my new underwater housing from Seacam which worked perfectly. Considerung my lack of experience I'm quite satisfied with the result. I used a D800E camera with either a Sigma 15mm FE or a Zeiss 21mm lens and no flash.
Here are some images from this trip:
If you are interested in some landscape images from this trip or some more background information you can find both on my website wild-places.com.
I would really appreciate a feedback regarding my images.
