It would be curious to see a list of slowest alt-photo processes. Not that one
can not drag these
processes out ( example would be many many layers in building an image). But a
list of process insensitivity to
actinic light would interesting.
The longest times that come to mind for myself is working the Physautotype, the
Becquerel developed
Daguerreotype, and the cold-mercury developed Daguerreotype. The range is from
four to thirty-six hours.
Anyone else practicing patience out there? Perhaps the pinhole practitioners
have some remarkable times.
Didn't someone make an image that lasted months to create with a pinhole camera?

The second part of your question: timewise, if it is gray and rainy
outside, expect a very long exposure with traditional cyano. Someone will
correct me if I am wrong, but if I remember, it is the longest time of the
alt processes, and even moreso if you are using traditional cyano mixed 1:1
