Lovely pictures with a fairytale feel to them. I have added the Biometar to the lens list and should show up on your quick lens set in your exif data window for quick assignment to other photos.
This series of Winter Photos was taken on my 1972 Pentacon Six made in East Germany by Carl Zeiss Pentacon and the lens is the 80mm f2.8 Carl Zeiss Jena Biometar. I used outdated Ilford FP4 220 size, home-processed in a home-made developer Formula PH35. Grad Yellow Filter used on most. This one I did a 20x16" Exhibition print and it got some awards at my Camera Club.
