This is very useful; thanks. I remember Ansel writing about footcandles.
When you measure the light with a lightmeter, are you measuring a gray card or a white card?
I got an email from John Sexton's assistant who said that his darkroom print-viewing place has an EV of 7 off a gray card, but his light for dry prints is brighter.
