Ursula Ferrara has proven us a few of her uncommon and inventive DIY tasks earlier than. And this time, this proficient woman has raised DIY to a brand new degree. Utilizing solely cake molds and a few epoxy resin, she made her personal large-format lenses and took some images utilizing them. She shares her course of in a brief video, so you’ll be able to attempt it, too.
Ursula began with shopping for epoxy and some spherical cake molds. You possibly can go along with one thing like this, or get a devoted epoxy mould. It began with a variety of experimentation, trial, and error. Ursula made dozens of lenses of varied sizes, curvatures, and thicknesses. She gave them completely different rudimentary apertures comprised of some darkish cardboard. Nonetheless, the primary images she took had been blurry. So, she determined to dedicate extra time to studying the idea earlier than one other try.
She made a plano-convex lens (the kind that has one spherical and one flat floor). She then added an ideal spherical diaphragm round 3cm (1.2”) behind it and connected her lens onto her large-format digicam. And bingo – she bought some fairly sharp images this time! I’m amazed at how sharp that is for a DIY lens, and the way clear that epoxy is.
Ursula beforehand made her personal 16″ x 20″ digicam totally from scratch. So, I believe this can be a DIY venture that comes naturally and leans very properly on her earlier concepts. She used her newly made DIY lens on an 8×10 Eastman Business large-format digicam, and I’d like to see a lens that she made on a digicam that she made. How cool would that be?
