Hi all,

I'm just starting out on the B&W develope and process road, and am slowly
gathering the gear to start a basic darkroom.

Everything I've read states that unexposed film (I'll be using B&W 35mm)
needs to be handled in complete darkness, you can't even use a safelight
with it. So I have to practice loading the bulk film loader and then the
developing tank in complete darkness.

My two questions are:

Has anyone found a way of not doing this in complete darkness, eg.
night-vision, infra-red or special safelight filter?

When handling the film, how important is it to keep your fingers off the
actual film face? Obviously handling on the edges would be better, but in
complete darkness with my clumsy fingers, I can imagine when loading the
developing reel I'm gonna grab the film face at least once.Would this ruin
that patch, or is it ok as long as the touch is light?

With thanks.

Nope, at least not for the type of film you'll probably be using, which
is referred to as panchromatic (meaning sensitive to all colors). You
can use a safelight with some orthochromatic film, which isn't [as]
sensitive to certain colors, but what you heard is true: *any* light
will fog the (pan) film.

Pretty important: skin oils can interfere with development and leave an
ugly impression on the image.

Relax; it sounds like you have the same jitters everyone has before they
actually handle film. There's an easy way to avoid all the potential
problems you're imagining: practice. Use some spare film and practice
loading it until you get the hang of it.
Keith Tapscott - 04 Nov 2005 10:20 GMT
You really have to load and unload film in total darkness and you will need
plenty of practice to get it right, I personally prefer to buy 135 film in
36 exposure rolls. There may be a chance of scratching the emulsion with
bulk film loaders if it is not done carefully.
It is very important not to touch the emulsion with your fingers as there
may be smears on the film which come from the natural oils in your skin,
this can show up when enlargements are made.
Using a bulk film loader would be better once you become more familiar with
loading a film spiral for film processing.
Unless you are going to be shooting and processing a great deal of films, I
would shelve the bulk loader and buy film in 36 exposure or 24 exposure
rolls, despite the slightly higher cost the convenience far out weighs the
hassle of using a film loader.

I concur. For somebody just getting started in darkroom work, it's
probably best to begin with pre-rolled film. It is admittedly more
expensive in the long run, but there's enough to learn about processing
film without complicating matters from the start with the bulk-loading
step. If you (the OP, that is) are concerned about cost, you can put bulk
loading high on your list of priorities, but AFTER you've mastered loading
film on a developing spool and processing it.

Fingerprints from loading modern film onthe spool don't show when
developed immediately afterwards. The developer is alkaine which seems
to dissolve the skinoil. But IR film does show the fingerprints.

The only light that I have heard to be safe during development of
panchromatic is in the following situation.  When developing sheet film
(don't try this with 35 mm film, it is too small to inspect properly),
after the film has been in the developer bath for about 3/4 of the
allotted time, you may hold it up briefly in front of a dim, dark green
safelight for purposes of inspection of the degree of contrast obtained.

  This is based on the fact that the dark adapted eye is
most sensitive to blue-green light so the light can be the
dimmest possible. Also, most panchromatic dyes have a dip at
about the same color, some modern films, like T-Max, do not.
The use of the light during development also counts on the
fact that the emulsion is substantially desensitized by the
development process. Nonetheless only very weak light can be
used for a few seconds without danger of fog. That's why
Kodak wants you to wait until development is three quarters
done.
  I believe that IR light with IR goggles are used in some
film manufacturing plants, mainly for trouble shooting. Most
panchromatic films have little or no IR sensitivity. This is
really not practical for home use.
  The first film I ever developed, some 55 years ago, was
orthochromatic, probably the old Verichrome. It was done
under a "ruby lamp" a small red light bulb. Those starting
out now will never know the thrill of seeing the image come
up on the film (it seemed to take forever) because there is
little ortho film made now.

I once went to the Kodak Kodachrome processing plan in Fair Lawn, New
Jersey. Recall that Kodachrome had an EI of 25 and 64. After I went there, I
believe they came out with some with an EI of 200, but that may be my memory
playing tricks with me.

They had a safelight up in the corner of the room right near the ceiling. I
believe it was a #3 or a #13. Anyhow, it was a dark green one, so dim all it
was bright enough for is to see where it was. They said this was to help you
orient yourself in the room. Normally, it was turned off.

Anything else they worried would fog film. And we are talking about slow
film here.

So no safelight for normal film. I do use Kodak OrthoLith film where a #1
red safelight with this, but it is insensitive to red. I often use it like
paper in my enlarger, and the red light helps me find the easel to put it
in. It would be better if the film had notches so I could tell the emulsion
side, but it does not. So I do like with color RC paper. I swish my dry
thumb ever so gently over it and listen. The emulsion side sounds a bit
different from the reverse.

If you can get a roll of outdated 35mm film cheap (really cheap), you might
practice with putting it into the film loader with the lights on, then with
a dim safelight, then in the dark. The main thing to watch out for is that
this stuff comes on a little plastic core that will fall out if you are not
careful. It may be that it is OK if the core falls out, but I like to keep
it in. It is not a spool with sides. But once it is in the loader, you can
do everything else with the lights on. I use an 0C safelight, but I am
probably being paranoid about this.

You should not touch the area where the image is going to be. But when
loading the loader, or loading the film into casettes, there is no problem,
because you will be touching the leader, and you will not be exposing images
there. You should wash the chocolate syrup, or salad oil, off your hands,
etc., before doing this, but otherwise, normal care should suffice.

You could certainly use night vision goggles, certain older emulsions
will tolerate the use of a dark green safe light for short durations.
The safe light is used for development inspection after the film has been
shot and is in the developer.

Its a very good idea not to touch the film, but unless your really man
handling it the places you touch probably won't appear on the final
product.

Doing it in the dark is no problem after you get the knack,
there is a bumper sticker there somewhere.  Get a few rolls
of expired/trashed/cheap film and practice in the daylight/
with eyes closed/in the dark until you get it.  If it is
not going well, put it away and try again in a few hours/days
- sometimes the film, she justa don' wanna go.

Sweat will mark the film: keep a towel handy to keep hands
dry.  If it is hot and sticky a fan can be a help.

With 35mm film there is _no_ reason to have to touch the
film face.

Most find the plastic Paterson reels to be easier to load
when starting out.

Some find that keeping the film in the cassette when loading
helps.  Pull the tongue out with a 'leader retriever' or by
popping the cassette open, pulling the tongue and slipping
the spool back into the opened cassette.

If your camera winds the film 'backwards' [most manual
load 35mm cameras] and the film has been in the camera
for a while then it will take a reverse set and be hard
to load and handle.  You may want to let the film rest in
the cassette for a few days or load the film from the
cassette

There are a few gadgets around to make loading film on
the reels supposedly easier.  I have never tried them.

Yep - called a "changing bag."  Oh - you mean, is there any way to
perform the process visually rather than by feel?  Nope - not with
panchromatic films, which have sensitivity into the near infrared.
They must be handled in complete darkness - no safelights, no special
illumination.

That being said, learning how to load your film reels and/or bulk
loader in the dark is just a matter of practice.  People have been
doing it for years, and it doesn't take long to acquire as a skill,
unless you have no coordination at all.

>When handling the film, how important is it to keep your fingers off the

It's very important to keep your fingerprints off the emulsion side of
the film.  Any oil/moisture from your hands is going to result in
uneven development at that point, and yes it will be visible on the
developed negative.  Oils will inhibit development at the point of
deposit.

When loading film reels, honestly the place you're most likely to
contact a non-edge surface is on the shiny backing side of the film.
As for touching the emulsion side - just don't do it.  Once you get
past feeding the leader onto the reel, you should only be touching the
edges, period.  Practice in daylight with a sacrificial roll until you
get the hang of loading your film properly.  Make sure your reels are
dry - moisture on the reels will cause the gelatin emulsion to get
sticky and prevent smooth feeding.  I personally find
Paterson/JOBO-type plastic spiral reels (where you crank opposite
sides to load the film in) easier to load than stainless ones - it's
way too easy to misload the metal versions if you're not careful.
Once the plastic spirals are started, it's almost impossible to
misload them.

This is definitely a matter of personal preference. My own is the opposite
of yours. Although plastic reels are easy to get started, in my experience
they usually develop increasing friction as you move past about half of
the roll, and on occasion this friction is so great that I've been unable
to get the film on entirely. I've tried all sorts of things to get past
this problem (being extra careful about drying the reels, trimming the
leading edge in a curve, etc.), but I've never really licked the problem.
Maybe it's humidity in the room or some unusual wear pattern on my reels
(I've used both Paterson and AP). I readily admit that not everybody has
this problem, but a Web search will turn up other similar reports, so I'm
certainly not alone.

My Hewes stainless steel reels, by comparison, are a breeze to load. The
only tricky part is getting the film hooked on the sprockets at the center
of the reel to begin, and that's not all THAT hard. A big caveat, though:
I'm talking about new Hewes reels, which use sprockets to center the film;
most stainless steel reels use clips, which are trickier to use. Also, if
a reel is dropped or otherwise abused, it may get bent out of shape, which
will mess things up completely. I've got a couple of generic used
stainless steel reels that are almost impossible to load correctly.

I presently use Jobo 2500 series plastic reels, and they work most of the
time, but sometimes I must remove the film and start over because it just
will not go in. On good days, I can just push the film in without wiggling
the sides.

The easiest SS reels to use I ever found were the Honeywell Nikor reels.
These have no clip or anything. You just center the film the best you can in
the gap in the core and load the thing. I have a clip in the 120 size reel,
and that is more problematical because if you get the film in wrong, it will
never load right. Fortunately I hardly ever shoot 120. (If I have to take a
tripod and camera out there, might as well use the 4x5.

  Bulk film holders are not too difficult to load. I use
the Alden 74, which is sold by most of the larger suppliers
and comes with pretty good instructions. The film comes in
100 foot spools with a plastic core. Its nearly a drop in
load. The film path and method of loading will be obvious
when you inspect the inside in the light.
  Loading cassettes is simple and is done in the light, the
loader has a light tight compartment. Bulk loading leaves a
couple of inches of fogged film at each end. It makes no
difference at the beginning of the roll since that will be
fogged in loading the camera but you will loose 1 or 2
frames at the end. It is possible to avoid this by loading
the cassettes in the dark but its a bother.
  The method of loading a developing tank depends on the
tank. I use quite old stainless steel tanks which I find
easier to load than plastic tanks. Load some scrap film in
the light to get the feel for it. For 35mm film its
necessary to cut off the tapered leader, easy with a pair of
small scissors. It also sometimes helps with any type of
tank to trim the corners. For SS reels the film is fastened
to a clip at the center and wound onto the tank by cupping
it slightly with your hand. There are loading aids which
guide the film, I have a couple but never use them.
  I agree with those who suggest starting out with packaged
film but it won't take much to get comfortable with loading
the tanks.
  Bulk loading saves a lot in film cost. The bulk spools
have a long shelf life. A 100 foot spool is approximately
equivalent to 20 36 exposure rolls of 35mm film. It is
sometimes useful to make up short rolls, especially for
testing. The Alden loader has good instructions for using
the frame counter. You will need some empty cassettes, some
masking tape, and a pair of scissors.
  Make sure you label the loader with the type of film in
it and the date it was loaded. If you load cassettes of the
same length consistently its also helpful to mark a tape
showing how many you have loaded.
  I find it very handy to have a good changing bag. You can
get plain bags for not too much and also very fancy "tents"
but the plain bag is good enough and not too expensive. They
are also useful for dealing with jammed cameras, etc.
  There is not much problem with touching the film. When
dealing with 35mm about the only parts of the film you will
ever touch are at the ends of the spools where they are not
going to be used for images anyway.

To all,

Many thanks for all your replies, been informative reading them all.

My main reasons for using a bulk film loader are:
The ease of opening the cassettes and extracting the film for the developing
tank. I've read and looked and knowing how I best deal with things, I know
I'll waste more film practicing opening a commercial canister and extracting
the film off the spool, then if I already know how it's attached and so on
with a bulk film loaded canister. Summary- If it's something I've already
put together, it'll be easier for me to take apart in the dark.

When first developing film, I can use 10 or 15 exposure lengths, using less
film than a 24 or 36 commercial can, as I learn the best develop, stop, fix
times etc.

My main concern regarding fingerprints as been allayed now, I initially
thought the film had to manually pushed onto the spiral all the way by hand,
I now see that once the end has been inserted, you just twist the reel ends
back and forth and it drags the rest of the film in itself.

I'll pop into a couple of local shops later and see about obtaining some
cheap out of date film to practice with.

Once again, many thanks to all who took the time to reply, much appreciated.

I *never* open a canister, I always felt unconfortable with a full
135-36 film (more than 1.60m or 5 feet and a half) unloading down to the
ground ...

I just retrieve the film leader (there are specific cheap tools for
this, look at B&H or Adorama under "film leader retriever"), cut the
leader and make a small champfer on the film's corner. All this done in
daylight.
Then, in the dark, I load the reel by extracting from canister/loading
on reel 10-20cm (4-8") per time until I reach the end of the film.
At the end, you just cut the film close to the canister and that's it.
Some will probably tell you this way the film passes twice on the felt
and may be scratched, but in more than 25 years, it never happened to me.

In 35mm, films are rigid enough that I just push them in the reel by
hand (holding them by the edges) without needing to move alternatively
the flanges of the reel.
All you need is clean, dry reels and dry hands. Its mainly moisture on
the gelatin side that makes the film difficult to load.
You can use an hairdryer to remove any moisture before loading.

Just buy the cheapest 135-36 roll film available. You need the 36
exposures as, usually, it's the last part of the film to be difficult to
load.

Getting film out of a cartridge isn't like opening a computer and
adjusting hard drive jumpers; light is not required, or even all that
helpful. Two approaches are common:

1) In the light, use a film leader retriever (they're inexpensive) to pull
  the leader out of the catridge. Alternatively, if you've got a
  manual-rewind camera, don't rewind the film all the way -- just enough
  to get it off the takeup spool but not fully rewound into the
  cartridge. Either way, this leaves you with an exposed leader, which
  you can trim. You then turn off the lights and load it onto the
  developing spool without opening the film cartridge. When you've pulled
  out all the film, cut it at the end. This approach has the advantage
  that it minimizes the risk of your touching the emulsion or getting the
  film dirty if you drop it. If you bulk load some, but not all, of your
  film, you can re-use the commercial cassettes by taping your bulk film
  to the stub of film that remains on the commercial cassette. This
  method of developing reel loading has the disadvantage that if there's
  any dust in the felt trap, it can cause scratches on the film.

2) In the dark, use a bottle opener to pry off one end of the film can,
  remove the film spool, trim the leader, and load the film onto the
  developing spool. When you reach the end, cut the film. The bottle
  opener can be the type you'd have in your kitchen or a special opener
  made specifically for film cartridges. I've used the bottle opener
  attachement on a pocket knife without problems. This approach has the
  advantages of not needing a film leader retriever and of minimizing the
  risk of scratches because of dust in the film cartridge's felt light
  trap. It has the disadvantages of greater risk of fingerprints or other
  contamination on the emulsion and of essentially destroying the film
  cartridge, so it can't be re-used for future bulk loading.

Neither approach is particularly difficult. When using bulk-load
cassettes, you'd probably use a minor variant of #2, in which you unscrew
or pull off the cap of the cartridge without the help of a bottle opener.
The bulk cartridge can then be re-used.

Overall, learning to use the bulk loader will probably be harder than
learning to unload a commercial cartridge onto a developing reel. This
isn't to say that bulk loading isn't worthwhile. I bulk load most of my
B&W film. I do it for the cost savings, though, not to simplify loading my
developing reels; that simply isn't an issue.

Be aware that you're more likely to see surge marks and other developing
artifacts with very short rolls. I've not noticed any problems with
24-exposure rolls, but when you get down to under 10 exposures or so,
development may become uneven. This can make judging the proper
development times difficult.

With plastic reels, yes. Stainless steel reels are loaded from the inside
out. You touch the edges of the film to guide it into the reel. Either
way, touching the emulsion is unnecessary (with the possible exception of
a bit at the beginning), but can happen by accident, particularly if you
remove the film spool from its cartridge.

This is why I feel talking to people is important, the books don't mention
this.
What causes this? I would have thought there was more danger of developer
not getting round all the film with the reel fully loaded with say 36ex
because of less space, than with a 10ex?

  I think the problem here is due to excessive turbulance
when agitating. I must say that I use short rolls to test
cameras and have not had this difficulty but it probably
depends on the tank and method of agitation. Short rolls are
sometimes useful but waste film because there is a certain
amount of film used up for leaders and lost at the end and
that stays the same regardless of length.
  Again, the bulk loader is simple to use and tanks just
take some practice, which you can do in the light.
  A note about cassettes: Kodak cassettes have crimped tops
which can not be removed without damage (a bottle opener
takes them off). Most other cassettes have tops which will
pop off when pressure is put on the long end of the spool.
They pop back on when reloading by compressing the cassette
sides a little. Kodak did this to prevent bulk loaders from
selling film with Kodak labels on it. The cassettes can be
reused by using a film retriever, as others have mentioned,
and cutting off the film so that there is a little tongue of
film left to which the new film can be taped. Empty
cassettes for bulk loading are available from large photo
suppliers like Calumet, Freestyle, B&H, etc.;they are cheap
and can be reused many times.

The sharp end of a "church key" (older readers will know what I mean!) type
can opener works better than a bottle opener.  The hook that grips the edge
of the cassette lid has a better shape (you can round over the pointy piece
with a file or grinder a bit)..  You can still find them in housewares or
check in sporting goods for a stainless steel model that won't rust.

And as far as the loading bit I always tell people that after the first
thousand rolls or so they'll have a lot more confidence.  It just takes a
little practice (but I still managed to screw up the first roll I loaded on
a stainless steel reel).

As one respondent suggested, wash your hands before handling the film.

In addition, you could also buy some cotton gloves, either locally or
through mail order, like B&H (http://www.bhphotovideo.com), as an additional
precaution, though merely washing one's hands and exercising care will
suffice. And, as others have noted, with practice you'll be able to deftly
load it onto the developing reel.

If you use Kindermann stainless-steel reels, they make a quick-loader that
makes loading nearly foolproof.  I strongly suggest that you try to find
one.

Depends on how dirty your fingers are. The dirtier the fingers, the more
you will affect the film. It depends on which side you are touching, the
emulsion, or the other side. You can scratch the emulsion side much
easier than hurting the other side. Fortunately the emulsion side curls
in, so it's not the one you are most likely to touch. Be careful, and
don't worry about it.
