@pinhole_dreamer: Go to http://www.mrpinhole.com/calcpinh.php and click on "pinhole exposure guide"... of course, you still need to calculate recoprocity for your particular film. If you get a good exposure with guesstimating, I see no reason for complicated calculations, though. I usually just note the Sunny 16 exposure time from the pinhole calculator and guess from there: A little cloudy is 1 stop more, shadow is 2 stops, dark clouds is 3 stops, and so on. When the exposure is several seconds to minutes, a second more or less doesn't really matter anyway.

I've never figured out the "Sunny 16" rule...and I'm horrible at math. I just guesstimate. If it's really sunny, 1-2 seconds with the one one thousand method...and if it's kinda cloudy, 3-4 seconds. Really cloudy? 5-8 seconds. If it's SERIOUSLY cloudy, I don't bother.

My general sense is with pinhole it's better to err on the side of over exposure -- easier to have to draw out the print making exposure than have no shadow detail on the negative.

I still guesstimate. I'm more of a "just give me a camera and I'll shoot and see what I get." Sometimes, it's a total failure. Sometimes, I get a roll of happy accidents. Sometimes, it's a 50/50 coin toss with what I get. I'm mostly happy with my results.
