$7.00 fun
Here’s proof that you don’t need expensive brass lens to have fun with collodion. Perused Surplus Shed and found an Achromat Cemented Doublet for $7.00 with a focal length of 333mm and diameter of 42.7mm giving an aperture of roughly f/8 at infinity.

After wrapping black electrical tape around the lens (I plan on blackening the edge with permanent marker next time), I chucked it up on an lens iris clamp and mounted it on the Gundlach 4×5 Korona.

I grabbed my favorite succulent and mixed some Ol’ Workhorse – the result is quite pleasing.

I really need to clean my scanner. Given the slow speed of wet plate, there’s an abundance of lens formulas available at Surplus Shed for some collodion adventure.
