I know, from working years in a camera store and teaching photography
classes, the following: Lots and lots of picture takers talk and talk
techniques to death and never making any prints. The only way to find
something out is to TRY IT! In regards to reciprocity failure and
development times

This is not an actual increase in development at all this is actually washing
out
the developer in the highlights and allowing the shadow values to develop very
very slowly. This slow development actually brings full detail to the shadow
areas and the highlight areas do not overdevelop.

If reciprocity failure has caused an underexposure of the scene, then
increasing the development is simply going to increase the contrast of the
scene. If shadow values have not received enough exposure, then no amount of
developing is going to bring them back.

Actually, this has more to do with working with sheet film, as o
eet film so I do pay attention to exposure vs development for each
exposure, but as it turns out, it's unnecessary to make additional
corrections with HP5+ in development times for long exposures.

Hello Shannon,
For longer exposures I always use a water / developer technique. I expose
my film normally and figure any reciprocity law failure as need and factor
that into my development time like usual. I ususally use this process when
I shoot at night but it also works for long exposures dur
I, too have been noodling this. I've had sucess with taking care of all of
the reciprocity corrections at the time of exposure. I process normal.
The whole thing about overexpose and under develop, or underexpose to over
develop never made sense to me as the conditions under which I shoot cou
Sorry to have a one track mind, but I am still thinking about whether you
need to change your development times when you make long exposures. The
theory seems to be that highlights expose more than shadows during long
exposures, so that you should under-develop. But, when I do this the
highlights
