    One- it's just 30 metres long....:)

    I've been told that you should get 20 rolls of 36 exp from a 30metre roll,
    however I invariably only manage 19 rolls. Maybe I waste too much trimming
    off - mind you I get 37 shots on each roll.

    Eighteen and change for me but I started shooting 30's instead of 36's, it's
    a little less of a wrestling match to get it all on an 8x10 contact sheet
    and leave room for a strip with my filing data.

  5. ..............about 18 36-exp lengths.

  6. okay...let's see now: image size is 24x36mm. Allow extra 2 mm between
    frames for total of 38mm per image lengthwise. 36 exposures x 38mm = 1368
    mm or 1.368 meters. Say 25mm for trailer and 100mm for leader for a total
    of 1493mm...say, 1.5 meters a roll of 36 exposures. 30 / 1.5 = 20 rolls.
    Of course, ymmv.

  7. Do you save a lot of money by getting the film in bulk ? And which film
    can be bought in bulk ?

    Thanx.

    Depends on what you pay for the bulk roll and what you pay for factory
    rolled. I think I'm saving about 50%. Quite a few films are available in
    bulk form.

    Most 35mm film can be bought in bulk. Buying in bulk costs about half of what
    it costs in the cannisters.

    You have to watch the prices of the pro-packs though. Not to long ago I was
    at Calumet putting in an order for a 100' roll of Kodak 100vs for $119 a roll.
    Depending on the quantities I had been buying it I was paying $9-$11 a roll.

    While the salesperson at the counter was putting the order into their computer I
    looked at the refrigeration case behind the counter and saw a 20 roll pro pack for $129!!

    I don't know about everyone else but saving $10 is worth bulk loading the film cassettes.
    That is one of the few exceptions I've seen.

  11. Actually, the cost savings can be more than half once the base cost of a
    bulk film loader and a couple of dozen cassettes is paid for. For
    example...from Adorama:

    Ilford Pan F Plus
    100 ft roll (= 20 36 exp cassettes): $25.50
    one 36 exp cassette: $3.09 20 36 exp cassettes @$3.09 = $61.80

    Agfa 100
    100 ft roll: $23.95
    one 36 exp cassette: $2.99 20 36 exp cassettes @$2.99 = $59.98

    Kodak Tri-x (USA)
    100 ft roll: $21.95
    one 36 exp cassette: $3.59 20 36 exp cassettes @$3.59 = $71.80

    B&H prices will show a similar relationship, I'm sure....but I'm having
    difficulty accessing the B&H website just right now.

  12. 35mm film has 8 double (still camera) frames per foot. A
    normal 36 exposure cassette load is five feet, the extra
    being leader. 30 meters translates to about 19 loads
    although you will get a little less due to fogged leader
    unless you do all the loading in a darkroom or changing bag.

    Plus buying "ready rolled" means your frame numbers come out right :)

    RF,

    If you really want to minimize expenses and maximize the useable frames
    from a bulk roll, you may want to use the technique some clever Brit
    posted here a couple of years ago.

    He hung a film clip from the ceiling of his darkroom so that when he
    secured the end of the 100 ft. roll in the clip and stretched it down to
    the counter top he had exactly the length he wanted for his frame count
    (20, 27, 30, 38, whatever you desire).

    He cut the film at the counter top level and then proceeded to roll it
    onto a spool right up to the clip and then put it in a cassette. His
    completely manual process was somewhat like rolling your own cigarettes,
    or whatever, resulting in no film lost to fog at the spool end.

    You can finish it off by using a razor blade or Exacto knife and a
    wooden template to cut the leader.

  15. Thanx for the info.

    Are there good bulk film loaders on the second hand markted, or is it
    saver to bye a new one ?

    Bye.

    I've heard of various people rolling film in the dark to save the few
    frames each roll. I guess with a 100' of film the wasted frames adds up to
    one 36 exposure roll.

    Personally if I was that worried I would still use a bulk loader. What I
    would do is tape the spool on in the dark. Close the loader up and then load
    the film. Turn the lights back off. Open the loader cut off the film and
    close the loader. No risk of fogging the whole roll of film. Or worries
    about dropping it.

    They're not expensive enough to take a chance with a second hand one. The one
    I like is one I got from Adorama. It's the one that the put their name on.

    I like to buy film locally so I end up paying a bit more for the film. Most places
    give a price break after 5 or 10 rolls of film. I never actually ran the numbers any further
    then a approximate estimate. Thanks for doing the research and presenting the actual numbers.

    As you've demonstrated there is a significant amount of money to be saved buying
    the film in bulk.

  19. I get a 20% discount if I buy 5 rolls of film at a time here in Israel.
    I would have to buy 5 100' rolls of film to get the same discount. Not
    very likely unfortunatley. So it's cheaper for me to buy pre-rolled
    film.

    Buying film mail order is not an option. The chance of a person importing
    via the mail or baggage a roll of film and not having it go through an
    X-Ray machine is very small. Especialy now that the customs people are on
    strike. A strike here means that every shipment and every bag gets X-rayed
    and then opened. Also a shipment of film would cost $25 to ship from the
    U.S. or Europe.

    Geoff.

    ....


    nov2103 from Lloyd Erlick,

    That's a venerable old technique. I thought I was a clever
    teenager when I came up with the zero cost idea of
    stretching the film out horizontally. I'm sure there are
    personality tests that could account for why I never thought
    of hanging it from the ceiling. It was a low ceiling, too...

    But something I could never understand: why isn't dust a big
    problem for people who do this? Large format workers
    complain bitterly about the difficulty of loading film
    holders dust-free, and yet 35mm film is typically enlarged
    to a much higher degree, so you'd think the dust would be
    even more of a problem.

    I suppose it's the felt lining of the 35mm cassette opening.
    No doubt it's a specially designed fabric that is incapable
    of scratching or causing static electricity. Since it has
    undergone such lengthy testing in the real world, isn't it
    time large format film holders had it installed on their
    dark slides so the film could be wiped just before exposure?

    I don't want money for this idea. I just want my name on all
    those new darkslides...

    regards,
    --le
