My 14x17 & XRAY Film

[Andrew O'Neill]

I wasn't sure where to post this video, as it shows me working with my 14x17 DIY camera, with XRAY film, developing it in the darkroom, and then making a kallitype print from one of the negatives. @MattKing if it's in the wrong place, please feel free to shift it. Thanks!

Good Job! And with moving that around you can skip a gym membership.

Very cool, Love your work.
My 14 x 17 set up is a little more agricultural than yours.

...and regular visits to the chiropractor! Thanks!

Wrong exposure for the yellow 15 filter - should be 1-2/3 stops instead of 1.

Not for me and this X-ray film. I've been using this combo since 2008. The same goes for HP5, Acros, FP4, Pan F.... Manufacturer's recommended factor is too high for me. 1 stop maintains zone III density. A densitometre confirms this for me, as well as a print.

That's what I thought also. Some of the manufactures don't publish the filter factor with the specifications anymore - probably because filters nowadays are used with in-camera metering systems. I recently purchased a yellow 15 4x4 filter and measuring against the blank white of my laptop screen it indicated a 1-stop loss. Then I took the filter outside and held it up against the blue ski opposite the sun and sure enough it measured 1-2/3 stops. I theorize that the difference in the readings can be attributed to the lighting source.
