I bought some "magic lantern" style glass slides (positives) on Sunday at a camera fair.
Monday night I went into the darkroom with my AristaII ortho litho film and duped the slides.
Today I printed them as cyanotype.
I don't know where these slides are from originally.
I should point out that eye hospitals still invert eyelids as I've had it done and that's how they diagnosed my hayfever They used a flat metal object not dissimilar to a spoon handle, though.
