I haven't been using this lens in a while. Couple of days ago i gave it a shot:


Bleached cyanotype toned in yerba mate.

Very nice result. Would you mind describing the printing process?

After i got the negative printed on a transparency film with my inkjet printer, i coated a piece of paper with cyanotype emulsion and baked the sandwitch at a UV lamp for 10 minutes. Developed the print in acidic water and toned for around 1minute in strong yerba mate infusion. Long wash afterwards, around half an hour. It dries overnight

What an intriguing process!

That's an interesting process, and a wonderful result.

The bellows lens, I'm not familiar with these - they are designed to get infinity on a bellows?

Using a plain metal m42->f-mount adapter it can focus past infinity on my nikon camera.

Great result. What printer did u use to print the inkjet negetives.
I am looking for adjustment curves for Canon printers.

For alternative printing process.. Here is a great blog i am following.

I know that blog: it's making me mad not to have access to their resources Smile

To answer your question: K3 inks on Epson printer. To get optimal results you have to redo the compensation curve every time to change paper, base exposure, chemistry composition, sometimes even the processing temperature. What printing process are you using? I only dealt with cyanotype and van dyke.

I can help you with the curve if you want to. Contact me on ym please.

This is another cyanotype toned in both yerba mate and black tea. Till now it is the best result i got:

Thanks a lot. I will get in touch with you on YM.
Actually i have got everything ordered for Cyanotype, Van Dyke & pallidium. But i don't have the printer to print it. I had access to a Canon printer, but no curves were available.

Easy job to create the curve. I'll tell you how

Great print and great posting, could also be in Darkroom section.

Technically there's nothing dark about the whole process: i coat the paper and print in full daylight (joking). Thanks for the nice comment Orio.

There's a VanDyke, the best i got till now regarding dynamic range (sorry, no mf lens here, just Nikkor 85mm 1.8 DX):
