Burbank Greenhouse salt print

untoned salted paper print from calotype
printed 20 November 2025

Strathmore 500 vellum finish drawing paper recently prepared with rice starch and NaCl.
I usually expose salt prints in 4 stages:
1) with paper diffuser aimed East away from sun
2) with paper diffuser aimed at sun
3) without diffuser aimed away from sun
4) 2 or 3 minutes with no diffuser direct sun.

I forgot to put the paper diffuser on when I started and didn't think of it until 7.5 minutes. I put the diffuser on then. The print was already overexposed after just 5 minutes of step 2, so I skipped step 3 and only used 1 minute direct sun.
