If you like the simple process (and low price!) of cyanotype printing, but wish not everything was bluish. Why not try toning your prints! You will be surprised how different the print appears. This time I have decided to tone my prints in black tea. It is said that it produces a warm black/brown shade! In my opinion the image below came out best:
In the image to the right you can study how far I bleached the print. On the top you see the dried original from the flatbed scanner. Number two is briefly bleached. Only 15 seconds. Number tree is bleached for 30 seconds, and the last one for 60 seconds. After the bleach bath I rinse the print in water for at least one minute. If you bleach on eye measure, start rinsing in water a little before you think it is bleached enough. Remember the print will continue bleach for a while after you have removed it from the bleach bath. Photo of the bleached prints were taken when still wet. Sorry about the glare.
Bleaching and toning cyanotype prints is a bit tricky. There are many variables; paper quality, under/over exposed image, bleaching time and toning time. All those variables are essential for a successful result. My best advise is to experiment with several prints. The result will vary, and do not judge the print before you have seen it dried. I performed some pre tests before I completed this one, and found my paper to stain a lot with long toning baths. The print was completely ruined after 20 minutes, and I decided 12 minutes toning was enough for this test. Another make of paper might produced better (or worse) result.
Out of twelve cyanotype prints, bleached and toned differently I have this result:
From the result I see that the none bleached prints ends up too dark blueish. And the longest bleached prints is a little washed out. I think the best one is number 6; 15 seconds bleach and 12 minutes toning. The darkest parts are black and warm brown in the highlights without looking washed out.
In this test I used Arches hot pressed 300g watercolor paper, Lipton Yellow Lable tea, and Stabil krystall soda (Sodium Carbonate). And of course tap water from Longyearbyen 🙂
