Hi folks, I've been toiling at the - traditional B&S - cyanotypes tonight and have a couple of questions: 1. Can you retain highlight detail? I apreciate the process is said to be self masking but I have tried to print the Minster Church image in My Gallery using this process - I have the exposure up to 20mins at the moment and I am not sure I'm going to get there even though the shadow areas of the pews are retaining detail. I am using a brilliant white cartridge type paper. I had coated some Arches Platine yesterday and ran a test with that and got a pretty reasonable result after 6mins even though the paper looked a little odd after being in a paper safe overnight. 2. How much do different papers - I assume the ph levels - affect the final colour of the image - the Arches Platine appears much paler compared to the brilliant white stuff that I am currently using. Many thanks in advance, Carl.
