I tried out some cyanotype prints the other day, when the sun was really strong. I’m not happy with the result, it’s too blue, there’s no white, no contrast. I gave the prints 5 minutes in the sunshine and I think I might have over-exposed them. The instructions on the packet of chemicals were vague – 3 to 30 minutes depending on conditions. I’m going to try some in a UV Unit next, as that will be accurate.

Thanks for the advice, I was doing it so wrong! I’ll try again WHEN we get some more sunshine, never know when that will be in a British summertime 😂
Smiles! There are loads tutorials on Youtube too. That’s how I learned. Have fun!
How long were the prints in the wash after exposure? You can do a double exposure by washing off the print with washing soda, recoat and reprint. Some of the previous print will still show and will give it some texture. Five minute exposure isn’t really too long. I mainly use the wet method and it stays out for hours and sometimes days.
Thank you. I think that maybe I didn’t wash it for long enough, just 5 minutes before I put it to dry in strong sunshine.
Next time wash for 10 minutes. Even if it looks as if the blue is washing away. It comes back promptly. Also let it dry in a heavily shaded area. Good luck with the next batch!
