The model here is Cristina Yakovleva, Russia. Working together during one of our summer session. I love to use the Гелиос 40-2 for such works, as the swirly bokeh is amazing.
I also appreciate to work it with 35mm film photography. The photo is without retouch concerning the swirly effect, but has a contrast/tone LR work.
It is very funny to look at the EXIF that the 5d wrote in file... :-) m42 with adaptor..
