Hi! I’m very new to cyanotype so it’s a lot of trial and error. The two prints below are made on the same paper and then washed under cold tap + H2O2 spray
The richer blue one was developed under the sun, and the pale one was developed under a 50ish Watt UV lamp for 10ish min (the time was chosen based on some info I found here).
Can someone explain how come the second print lost all its ‘blueness’?
Thanks
