There have not been any puffin images lately (at least none on this page) so I will post one of my favorites from Iceland.
Canon 1DX
600mm
ISO 1250 SS 1/1250 F 6.3
Shot in landscape orientation and cropped to vertical.
Pretty much straight out of the box- Usual sliders in LR + decreased magenta and NR to BG and levels in CS5 , then off to NIK EFEX PRO for DE(detail extractor)/TC (tonal contrast) at 20% to blacks and 15% to whites and USM to JPEG.
Comments and critiques always appreciated and learned from with thanks,
Gail
