Burbank Greenhouse calotype

Calotype made 18 November 2025
Luther Burbank's greenhouse

Details:
2nd calotype using the Guillot-Saguez process. This one came out a little better but I was still too cautious about adding Aceto-nitrate of silver during development.

5x7 Eastman No. 1, Wollensak velostigmat
LV 16 sunny bricks, LV 15 sky, LV 13 shady bricks, LV 10 background trees
Decided on LV14 but added an extra stop for red colored bricks.
Exposed: 32m @ F/22

Vidalon Vellum paper
iodized 4% KI, 1% KBr
sensitized 7% AgNO3, 12.5% acetic acid

sensitized at 11AM, exposed at 2PM, developed at 4PM
lost upper left corner when positioning on glass plate.
paper was wet a long time and lower left corner came mostly off during processing.

100ml ss gallic acid, 4 drops ANS
added about 1/2 eyedropper at 5 minutes, another 1/4 at about 10m and 15m.
done at 20m.
still would like to see a little more density ( could just see newsprint through the sky ) and next time I will start with more.
