Sometimes It's the Little Things
The enlarger is working again. Five years in storage had let a tiny bit of corrosion get on the lamp pins. A wiggle or two on the contacts and voila.
Went around with a meter and the IIIa today. No photos after 8AM, but the meter got used anyway, taking notes.
NVIDIA interiors are EV 7 day and night. My dining room is EV 5, kitchen EV 6. Bedroom around EV3, depending on distance from the big paper lantern. So now I don't need a meter.... NVIDIA is three stops down from open shade which is four stops down from sunny-16. The dining room is two stops down from NVIDIA. What more could I need?
