Paul,
If you are satisfied with the results that you get from the OM2, why not use the
OM2 itself as the light meter? Assuming that all else is equal (lens field of
view, film, etc.) between the two cameras, it seems to me that all you need is a
double cable release and some sort of bracket to mount both cameras on a tripod
together. Pressing the cable release opens both cameras' shutters; after that,
just release the release when the OM2's shutter closes. Timing's not that
critical in this situation.
Place a snippet of film in the back of the OM2 so that the meter works properly.
regards,
m.

Subject: [OM] Metering for fireworks
I take photos of fireworks, i.e. large scale display fireworks.
Exposure time is the difficulty. I get good results from an OM2. The rule
of thumb is to use the aperture which is the nearest reciprocal to the film
speed, e.g. if the film speed is 100, the reciprocal is 1 / 100 which
equals 10, so the aperture used is the nearest: f11.
The OM2's automatic exposure does the rest, exposing at anywhere between 8
and 20 seconds, cutting off when enough light has reached the film. In this
time the photo will consist of any number of shell bursts, stars,
bombettes, etc.
I've previously used a Minox 35 to similarly good effect.
The problem is that both of these are 35mm and will only stand a certain
amount of enlargement.
I also use my Hassie 500cm but the exposure time has to be estimated
entirely by subjective judgement. I've had good results but also a high
failure rate.
The question is - does anyone know of an exposure meter which would do for
the Hassie what the built-in meter does for the OM2?
