I haven't taken snow pictures since the old film days, but I believe you
may have meant "underexpose" not overexpose. It's been decades, but I
feel that the amount of underexposure required was substantial, if I
wanted to be able to see footprints and other snow surface details - 4
or 5 stops relative to a light meter reading from a neutral gray card?

Content-Type: text/plain; charset="utf-8" I've found I've had the most
success with snow (or anything much brighter than neutral grey) by
overexposing and and bracketing. Makes post-exposure processing much
easier. Jim Coleman Upsala '75 http://www.linkedin.com/in/jamescoleman

What I've found over time is that pictures with significant amounts
of snow in them are my nemesis as far as getting things to look right
in processing, and now I'm wondering if other darktable users have any
particular tricks or ideas.
In real life, snow around here typically registers to my eyes as both
fairly bright white and having plenty of details (often both large
scale, such as footprints, and small scale texture and so on). But when
I process my pictures, I'm almost never successfull at getting the snow
bright enough that it feels white and like*snow* while preserving
detail and texture in it. If I get it bright enough that it looks like
snow, the details vanish (even if I try relatively strained processing
in eg the zone module); if I prioritize trying to preserve details,
generally the snow comes out looking grey and wrong and not infrequently
the details don't separate anyways.
So: do people have tricks they use when processing snow pictures?
Should I be looking at eg the equalizer module and its clarity preset to
really exaggerate contrast edges in my snow pictures?
Thanks in advance for any advice, hints, etc.
