Unfortunatley the 24 hr delay after iodisation was a mistake with this paper, see the scan with transmitted light, serious fogging could be seen emerging after exposure
15 min exposure bright day blue sky f/6,3 whole plate
Winther's tannin process with Sumac extract
Pre-silver brushed 5,2% AgNO3, dried iodised in 4% KJ for 10 min followed by 2 water baths of 10 min each (pure water) blotted off and dried
Sensitized just before exposure with sumac extract 28 drops, AgNO3 14% 7 drops, gl. acetic acid 2 drops made double.Exposed moist in a glass sandwich.
Developer brushed and sprayed with 25% alcohol for 1 hr 10 min
Developer consists also of sumac extract 28 drops, AgNO3 14% 7 drops, gl. acetic acid 2 drops made double. After brushing sprayed and left wet face up under cover, brushed also just with Sumac extract saving the silver nitrate for later to boost density.
Short wash before 2 x 10 min hypo and 1 hr running water bath
Canson Marker paper was pre-silvered and iodized the day before exposure and processing.
The paper behaved well when prepared pre-silvering and iodisation on the same day as exposure and processing.
