FIlm reciprocity

If you happen to use 120 film in your pinhole, give Fuji Neopan Acros a try.
This wonderful film has no reciprocity correction for the firs two minutes,
and only one half stop from 2 minutes to 20 minutes. This quality makes it
ideal for night and/or pinhole photographs. Last night I made 20 minute
pinhole exposures in some of the marinas here. They are terrific.
If you live in Japan, or have contacts there, you can obtain Acros in4X5
and 8X10 sizes.

Another respondent mentioned shortening development time when using long
exposures. The reason fro this is that as film is exposed for extended
periods of time allows the highlights to gather immense quantities of light
compared to the mid and lower tones. Extreme contrast is the result.
Decreasing the development time causes the highlights to develop less in
relation to the mid and lower tones thus reducing contrast.
