CARBON
TETRACHLORIDE
was long used as a very efficient cleaner of film. It removed
grease and muck with no trouble at all. Regrettably one nasty little
habit that it had was to ruin the human liver - also very efficiently!
This is why such cleaners as Thawpit have since disappeared from the
shops (it contained carbon tetrachloride) and th chemical is virtually
impossible to obtain now.
Can
anyone tell me if there is a substitute which is not so toxic but
equally good at th job and mor to the point can be bought in the sort
of quantities that an amateur would need. I`d appreciate your news.
ARTIFICIAL
LIGHT FILM
Type
A slide films are not exactly thick on the ground these days and those
few that are available are pretty expensive, so I have been doing
experiments (mainly to find a 35mm film that can be used to make 9,5mm
cine film) to find a good quality substitute for the genuine, pricy
camera stock. Kodak markets a tungsten balanced slide copying film,
which can be bought in a cassette of 36 exposures, or for greater
economy, as a 100ft roll. It is known as Kodak Slide
Copying Film Type 5071 and is processed in any standard E6
chemistry.
I
have found this to be rather good. The film can be rated at around
50ASA in tungsten light and as an added bonus can be used in daylight
with an 85B conversion filter. Needless to say it also makes an ideal
slide copying film! So
all things considered, is quite a versatile stock. Send me five first
class postage stamps and I`ll send you in return a 36 exposure sample
cassette. The cassette is reloadable, too, once you have tried the
5071 (because I have loaded the cassettes from a bulk length). I`ve
only about a dozen, so if you want one get in quick.
