The exposures that I sent you did not include reciprocity failure, so yes you
would have to compensate for that.
The exposures that I gave you were based on sunny-16.
They were also based on either a 18% gray card reading or an incident light
meter reading. The exposure suggestions with your

I meant to write f16 @ 1/125 sec instead of 1/100 sec (as indicated below).

Hi this is Lonnie:
I have a question about your answer to Bill about pinhole exposures @ f/500
with ISO 100 film.
Looking at my light meter without any reciprocity corrections a sunny f/16
exposure should be about 8 seconds @ f/500. If you have heavy sun as well as
bright snow I would use 4

Hi this is Lonnie.
Your exposure, I would try 4 to 8 seconds in bright snow with a bright sky,
which would probably give you a EV15 to EV16 with an ISO 100 film.
Glad to hear you are using an 8x10 camera. I am thinking of making an 8x10
camera out of banker boxes.

Dont forget,with polaroid film,too light is too long of an exposure..try to
expose the next shot for 1/2 as long..
Just my 2 cents..

Bill,
Here is a brief analysis I've done: Assuming bright open sky
conditions, shooting snowy scenes call for about +2 stops from whatever the
meter indicates for the snow. Using sunny/16, your exposure should be f/16
@ 1/25 secs. There are about 10 stops separating f/16 from f/500, there
Hello All!
I could use some help here. We just got a wonderful spring time
snowfall yesterday (10") and it got me out and about with my 8x10
pinhole camera (due to the extra light reflection of the snow). I tried
using Polaroid type 804 ASA 100 (first time using this film) and I can't
seem to ge
