Thanks for you comments

Try mixing your cyano type (A+B / A) with a 5% sollution of gelatine. It will cut your exposure by at least 50% (Light travels trough the emulsion, bounces backfrom the given support and exposes the emulsion from both sides). The gelatine cyano mix will stick to almost any material without any trouble. Also the cyano mux wont react with whatever is in your paper if you dont want to spend money on art papers. But the main advantages are are completly even contrast curve and you can use pigments within your gelatin! Yes…printing CYM with only two layers (shadows are cyano highlights will become your choosen pigment color / gold, silver black are super interesting too ). Be carefull with using clorine for boosting contrast and cyan density cause wet gelatin and clorin might not get along to well. But its not impossible. Toning your print with dye is now equaly easy cause dye and gelatine are very good friends. Got a job offer as a printing teacher today and thought i start practicing on the sofa! Good luck! Regarding pigments mixed with gelatin + plus cyano … high density of pigments of course extendes your exposure.

According to Wikipedia, a woman, Mary Somerville, originally invented the process but presented her findings to Sir John Herschel!

Thank You for taking the time to give a simple explanation of the cyanotype printing process. I love darkroom printing, but it is a whole process I just do not want to mess with anymore. I want to simplify my whole process with less gear and workflow. One or cameras, one or two film stocks, one or two printing processes, etc. and then experimenting within those parameters. Invariably, it is always about the print for me, something tangible from the intangible, not counting my minds eye. Shooting with pinhole cameras, home developing black and white film with caffenol, and printing with the cyanotype process (or other some other alternative printing process) sounds like my speed: slow and stop, lol. Starting with smaller 120 film negatives will be my first experiments because it is what I have on hand, just cute little Prussian Blue photos. Later, I can print larger negatives like you explained. Btw, your cute cat is spoiled rotten. I have two rotten ones myself. Much obliged.

How do you know your exposure time? Is there any way to tell if the exposure is good while exposing? Or trial and error?

People need to tape the edges of the glass to avoid cutting the crap out of their hands. Also, do you use negative images rather than just a copy on acetate?

@photobrake

Yes. Tape will do fine. I actually sand the edges, with a fine wet sandpaper. I forgot about that technique. Yes I print from a negative. I've been wanting to do that video, so maybe that will be next. Thanks for your comments.

olney. Make sure the light sensitive coating is completely dry before laying on the neg. Use a heavy glass pane to ensure complete contact negative to paper. Do not use any clips. Use a water bath to develop and wash the print. Do not forcefully spray it as seen in this video as this can abrade the image.

When did you start doing this?

Cyanotype is one of the safest printing processes out there. It could be an irritant and I always wear gloves. I always err on the side of caution when it comes to mixing it up. Water is what stops the development. Oxygen can make the blue darker. I enhance that by bathing the print in a solution of hydrogen peroxide solution and water. As far as archival, there are prints from the 1800''s that are still very vibrant although these are in a museum. Cheers
