Hi! I just had some fun with cyanotypes. The first two attempts came out OK, first one underexposed, the other one, a 40 minute exposure, turned out like this: http://blog.hform.se/article/167/for-real The third attempt was dissapointing. I have put together 11 6x6 negs as a little experiment, please check the attachment. I don't have a LF camera, so this was a "cheapo" way to get slightly larger cyanotype. Anyway, I coated a paper, let it dry about 20 minutes (maybe not fully), placed the cut up/taped up negs on the paper, put between the 5 mm glass sheets and exposed for 46 minutes. When I rinsed the paper I saw big areas that were indigo colored, ie more blue than the rest of the picture, that were not in the negs. I would call them blotches. I will scan this soon, but the print is drying in the darkroom. I'm thinking this could be the problem: 1. Not dry enough paper. 2. Not enough pressure on the negs and paper, ie negs weren't in perfect contact with the paper. 3. Overexposure. Any tips? BTW, this is what I use. 300 watt UV-bulb from OSRAM, called "Ultra Vitalux". It was placed about 40 cm from the glass. As a "frame" I use two 5 mm sheets of glass. I should get something to really hold the glass sheets together tightly, right? Do I need a more powerful UV-lamp? Thanks!
