Still not too sure about this one. This lens has been kicking around for the last 35 years or so, & I kept thinking there must be a photograph in there somewhere. Anyway, this popped into my head after a few cans of Pedigree.
The lens is a J. H. Dallmeyer (patents 1866 & 1909). There's no focal length marked on it but I estimate it's around 15". The lens is 8" long & weighs around 5.5lbs. It would have been stuck on the front of a massive, probably mahogany, studio camera.
The portraits are from an old leather & brass-bound family album from the 1890s. My God, those people were ugly! (The wife's side of the family of course.)
I struggled for hours to get the light rays looking realistic, & ended up photographing the bar code on a wine bottle which just happened to be at hand, & distorting it in PS.
Anyway. Over to you.
