I particularly like the way your lens renders out of focus areas. And the way it morphs from in focus to out of focus. I used to have a famous brand Tessar that was nice and sharp, but rendered the transition and o-o-f areas so harshly, it was a distraction.

What lens, out of curiosity?

You might find that 1:50 is too strong a dilution for your tubes with constant agitation. I was at 3 min in trays with 1:50. 1:100 or 1:200 might be the better dilution. Post your results whatever route you choose.

Thanks Lee. I'll definitely give that a shot. Are x-ray films super sensitive to temperature during developing? I'm thinking 20-22 degrees centigrade with Adinol 1:100. If the BTZS tubes don't work well I'll have to find a way to tray process I guess.

Did a test session with Chiller(Steve) with my newly acquired KODAK 2D
270mm G_CLAREN Lens,set for a BTZS file test and the neg came out real well,
did a contact print on Agfa MC Matt and could not be more happy, developed neg in trays,
developer Rodinal 1:100 15.45min under a Kodak no2 safe light.
Attachment 99609:)

Then we did a still life test and contact print reduced development by 10-15% and the resulting print
has now got me really impressed 8x10 print on Agfa paper.
the only spoiled part was a misaligned lens board(light leak) new one to make.

Here what I shoot with 14x17 FuJi xray films, and contact printed in Ilford MG IV

Huh??? Do you think I was being antagonistic? I don't really care that much.

Nice Sergei, perhaps I am imagining similarities.

I'm still here and working!

You are influential.
