Bender (Tin Toy Tintype)
My first ever dry plate tintype. To say that I was "pleasantly surprised" is an understatement.
5x4 dry plate shot in MPP with 150mm lens, with a +3 dioptre close-up lens taped behind the rear element.
The plate was 0.5mm aluminium sprayed with black polyurethane paint and coated with Rollei "black magic" emulsion. Exposure 4 sec @ f8. Developed in the following for 3 minutes:
5g Ammonium Thiocyanate
15 ml Rollei RBM5 hardener
30 ml Ilford Multigrade developer
270 ml water
No stop, just a water rinse. Fixed in Ilford Rapid Fixer 1+4 and 10 minute wash in cold water.
The developer was an experiment based on what I could glean from internet newsgroups and the Rockland tintype kit data sheets. My understanding is that the Ammonium Thiocyanate acts as a silver solvent, adding contrast and giving a clearer positive when the silver image is viewed on the black background of the plate.
More coming soon. I plan to do a series of "tin toy tintypes" (I enjoy alliteration).
