Calotype test of new batch
Heavily overcast noonish at 1 pm and pretty much in shade.
The measured EV was 10,5 roughly so the exposure was calculated to 18 min at f/8 using the reliable Tessar 180 mm for this half plate test of a new batch of 4 sheets to take to Italy this coming Sunday.
By the end of the exposure the light deteriorated further and was EV 9,5
The 4 sheets of whole plate can give me 8 exposures on half plate so a decision is needed very soon.
