Black and white film?

Hi, when i went to the store to buy my first safelight, the guy told me
that i can use this for black and white paper, but film can get ruined
by it because it is still sensitive to red light. but if i use black
and white film can i still use the safelight? i'm not very good at
doing stuff at the dark so i'd like to use the light if at all
possible.
thanx

Warm hands are a problem if you sweat a lot (hyperhydrosis)
Consider something like alum solution (sold in pool stores
as aluminium sulfate?) which is the basis of under-arm
deodourant. A weak solution - rinse your hands and dry.
It stops the sweat glands from working for a while.
Then after a few minutes try and load again - it might work
for you.

Yes. I am amazed at how fast my dentist can get the results of an x-ray. I
have had him take another one in the middle of some difficult procedure, and
check his progress before continuing!

Yes. I can see how that might be interesting to watch....but with my rather
poor vision, I wouldn't be able to see images that small anyway....I can't
even view my slides on a light table....I have to use a viewer, and a rather
bright light, or the outdoor sky as a backdrop. My father used to do large
format film developing in a black plastic/hard rubber tank. I don't remember
the details, but as I remember he did most of the work in absolute
darkness....The film was in stainless steel hangers that hung on the side of
the tanks like file folders in a filing cabinet.....He didn't look at them
until they had been in a fixer or stop bath for several minutes.....

I've just had a root canal done, so the Dr. was new to me. His setup was
slick. They took digital x-rays of the tooth before, during and after
the procedure. It was displayed on the monitor beside the chair inside
of a minute.

It is fun and interesting To see a film develop. Film in
developer has the image come up rather more slowly than
it does on paper and because the film doesn't have a
white support, the milky colour of unfixed film is
much more evident on film than with paper.
It is something worth doing once or twice for the experience.
As I said, most of the time ortho film is handled and developed
in darkness just like panchro film.

Back in college, I had the unique pleasure of trying to explain to a deaf
classmate how to load a film reel. I would hand-sign the words, and he would
feel my hands to "see" what I was saying. That was possibly the most
difficult roll of film I ever loaded!

I see no purpose at all in using any light to develop film.....Especially 35
mm film. Exactly what do you need to see? You put it on a reel in a can, and
then pour in the chemicals one at a time for the prescribed time. Even if
you could do it all in daylight, what would be the advantage?

Re: black and white film?

For fast ortho films of the Verichrome type (Maco PO 100, and
Ilford Ortho sheet films are the only modern ones I know of)
you want a Kodak Wratten #2 safelight filter or an Ilford
906 filter. The #1A filter is for ortho-litho films of the
Kodalith type and is not safe for the fast pictoral ortho films.
You might get away with a #1A filter for a brief time, but
if you plan to develop ortho films by inspection, the #2 filter
is a much better idea.
I have used a mini maglight with a #25 red Wratten gel over the lens
aimed at the wall for ortho film. The amount of light is just
enough to see by when my eyes are dark-adjusted and it appears
to be safe enough.
Most of the time, pictoral ortho rollfilm such as Maco PO-100
is loaded in the dark the same as panchro film. Just because
you can use a safelight doesn't mean that you have to use one.

As I have recently learned from the kind help give in this news group,
Orthochromatic B/W film is NOT sensitive to dim red light. Maybe
a red 15-20 watt bulb would be best. This kind of film is available
online if not in your local stores.
