Re: More Great Shots (loop 6B)

["Gary Cullen/Karoline Cullen" <gcullen@xxxxxxxxxx>]

another problem with spud shutters is that they are not consistent with
standing time between shots. What I mean is if you fire the shutter after
the camera has been sitting for some time (days, weeks or months), the first
exposure might well be a good 1/2 stop slow (overexposed) or more. This is
due to dirt or thickening lubricants in the shutter. Usually after the first
shot things loosen up s bit.  If you cover the lenses and fire the shutter a
couple of times before your first shot you will get better consistency. Of
course a good cleaning and replacement of lubricants would solve the
problem.

Regarding Spud exposures.
I usually allow at least half a stop to allow for certain innacuracies
in the measurement of the f apertures.
Depending on the prevailing lighting, I can give a whole stop.
I originally had a pretty steady exposure problem and had the
shutter tested at a local camera repair shop. They came up with a
fairly consistent shutter, but informed me that my marked f stops
were incorrect.
Perhaps this is a congenital complaint withthe breed?.
Sorry about R.M.M. closing.
