This is Ramsviksträsk in Björnö Nature Reserve on Ingarö in Sweden. It’s a beautiful place!
This photosphere was taken with my Canon EOS 550D and Canon 8-15mm f/4 L USM Fisheye Lens. I used a Sirui P-326S Carbon fibre monopod and the Nodal Ninja R1 head with the RD5 rotator.
All images was shot in RAW and post-processed in Camera Raw, PhotoShop, PTGui Pro and krpano Tools.
