Pinhole still life, quick wash in Sodium Hydroxide, then long wash in ground coffee.
– David Amos
Hey like these last couple of cyanotypes, the paper texture adds a whole other dimension. Took me ages to work out the subject matter.
Thanks Shane, yeah I was in two minds wether to put this one up, the exposure is very under. My calcs on the pinhole was a little off, I was lazy and didn’t get the light meter out and guessed.
I’m liking this series, David. Was the sodium hydroxide & coffee done as post-processing, or were they the initial developing agents? Sodium hydroxide is pretty severe stuff!
Sorry Duncan, I meant to write Sodium Carbonate. The develop stage is really just water, then you can “Bleech” out the print with Sodium Carbonate, ready for tonning with the tea, or Tannic Acid if you can find it.
That sounds more like it! Is this a true cyanotype process, or what? I don’t recall how that process works, so can’t relate your description to what’s going on. Have you written up your process anywhere? I can’t see anything in your journal. I know that soxy produces blue prints which are just inverted from the brown coffee-processed paper, but you seem to be doing more than that. We need to read the story!
Ha, you make me laugh Duncan, ok, ok, I will write something up and might even do a video. And yes this is a true Cyanotype process. like they did 200 odd years ago.
And also remember that this is a contact process, it is not an enlarging process.. the beauty of this process is that you can do it in the day time, unlike photo paper, which we all know that we need to have a darkroom do these types of prints.
Thanks David. Laugh? What did I say? I take my hat off to anyone who’s prepared to plooter about with highly manual techniques like this. Given a good darkroom space, I reckon I’d be having a crack at stuff like this. The textural qualities are wonderful, and the painted emulsion with its rough edge is so appealing. I reckon the next logical step would be to make these on handmade paper, with the deckle edge showing, and mount it on a darker background. Then you could really say “I made this”!
Yes, “I made this” this is what I love about this… as you might know Duncan I shoot weddings – a lot of weddings!!! And it is really satisfying DOING and CREATING photography for once, getting back to the real photography that was in the days of Adam Ansel and Paul Strand… these are the people I love to study.This process is VERY easy… I tried GUM BICHROMATE, but that process is blood hard… I didn’t like the results at all. With Cyanotype I got an excellent result the FIRST time I tried it.. The detail is amazing, I would really like to try Platinum, NOW THAT IS A BEAUTIFUL print. BUT EXPENSIVE!!!!
Wow, I’ve just been surfing in your gallery and am very impressed at all your technical experiments, etc. Great to see such creativitiy and such results too. Kasia
Thank you for your kind comments Kasia…
