My first attempt started to look good, until it hit the bath where it failed miserably. It was a 20 minute exposure, on an overcast day (not much sun this week), about 60 degrees F.
Exposed from a 4x5 negative on Canson watercolor 140lb paper using B&S Cyanotype kit.
The mountains and most of the foreground disappeared in the wash leaving only the tree areas (which are darker), and while I did wait until the blue started to reverse, I think it could have been exposed longer.
Thoughts are welcome, I'll try again tomorrow.
