220 with 120 backs?

[mark_spencer1]

I have read about the possiblity of using 220 film in the old

Hasselblad 12 backs. I havent tryed this and have my doubts as

to how this would work being these backs have a "peek-hole" in the

rear of the back and 220 film has no paper backing the entire

length.....Has anyone done this and can explain it...and what about

the counter......

I asked this same question several months ago. Please search the Hasselblad archives for answers to this question.

Hello Mark,

It IS possible to use 220 in the older (non-"A") backs. The procedure

is a bit complicated though. I have this book "the Hasselblad way"

where it is described in detail. I would worry about the film being in

the right plane though (pressure plate), though i have no experience

at all. if you're interested i could mail you the pages of the book.

Greetings, Han

Hello Mark!

I have used 220 film in my old Hasselblad C12 back for a long time. I

have not had access to any formal (i.e. from the Hasselblad people)

description on how it is supposed to be done, but my method have

worked fine so far: Take the 220-roll and load it as you would a 120,

but don't let the take-up-spool have more than a few turns of

backing-paper. Put the film-holder in the magazine and while peering

through the hole on the back of the magazine, wind the film until you

reach the point where the paper and film is connected. then close the

peering-hole with either the original Hasselblad light-thight plug or

(as I do) with a pre-cut piece of black, elastic (foamy)rubber. Then

wind the film another half-turn with the magazine-crank to advance

past the peer-hole-exposed part of the film, reset the

magazine-counter to zero and go! When you reach past 12 exp. reset the

counter once-again and expose the second half of the roll. Remember

that a too-long light-tight plug may lock the film-holder to the shell

- remove the plug (after film is completely wound on to the take-up

spool!) before removing film-insert. Good luck!

I have a 12 back dedicated for 220. I have the back completely taped

with thick dark tape, to avoid light leak from the back window.

 

<p>

 

To load the film, I check the film position from the front window (the

exposure window, removing the dark slide). When the film is right

about to appear in the exposured area, I can see a white tape that

tapes the film and the paper (this is Fuji slides).

 

<p>

 

Reset the counter right here, fire the shutter, turn to next frame,

then reset the counter again, it'll be ready to take the first real

shot.

 

<p>

 

But DOING SO WILL NOT GIVE ENOUGH FRAME SPACIONG.

 

<p>

 

The frame counter needs to be reset again after each shot for the

first two real shots. Allow the frame count to count up after the

third shots untill it reaches 12, reset the counter after that,

then take the rest shots.

 

<p>

 

REMEMBER, the film ends after count 10 or 11. (your back may be

different, depends on the condition)

I have a web page dedicated to this subject.

Mark,

 

Original Hasselblad instructions from 1965.

 

"The new 220 film has no protective backing paper and, therefore, no light must be allowed to leak in through the film window which must be made light-tight. The manufacturer has therefore made a light-tight plug which is fitted onto the film window, from inside the magazine, with the number "220" facing outwards. The magazine can also be sealed against light by affixing black tape across the film window. Like 120 film, the 220 film has an arrow going across the first paper section. But 220 film has no numbering system. It has, however, a dotted line, about 6" before the crosswise arrow and this dotted line is very important in connection with loading this film in the Hasselblad magazine.

 

 

To obtain the best possible results in spacing between the negative frames, the manufacturer has prepared three sets of instructions for the three variations in construction of the Hasselblad Magazine 12 now on the market.

 

 

LOADING INSTRUCTIONS

 

 

Magazine Construction 1 (Nos 001 - 19,999)

 

 

a) Thread the film in the usual manner onto the Hasselblad spool-holder. The protecting paper is drawn forward so that the dotted line comes to the center of the receiving spool, (see photo).

 

 

b) After the spool-holder is inserted in the magazine, set the exposure-counter window at 1.

 

 

c) Wind the film forwards 7 complete turns (14 half-turns).

 

 

d) Expose 12 frames (no stop).

 

 

e) Reset the exposure-counter window to 1.

 

 

f) Expose another 12 frames (no stop).

 

 

Magazine Construction 2 (Nos. 20,000 - 64,399)

 

 

a) Thread the film in the usual manner onto the Hasselblad spool-holder. The protecting paper is drawn forward so that the dotted line comes to the center of the receiving spool, (see photo).

 

 

b) After the spool-holder is inserted in the magazine, set the exposure counter window at 1.

 

 

c) Wind the film forwards, 10 complete turns (20 half-turns), or until the framenumber 8 begins to appear in the mechanism of the exposure-counter window.

 

 

d) Reset the exposure-counter window to 1.

 

 

e) Expose 12 frames (until stop).

 

 

f) Reset the exposure-counter window to 1.

 

 

g) Expose another 12 frames (until stop).

 

 

Magazine Construction 3 (Nos. 64,400 - )

 

 

a) Thread the film in the usual manner onto the Hasselblad spool-holder. The protecting paper is drawn forward so that the dotted line comes to the center of the receiving spoof, (see photo).

 

 

b) After the spool-holder is inserted in the magazine, set the exposure-counter window at 1.

 

 

c) Wind the film forwards 9 complete turns (18 half-turns), or until framenumber 7 appears in the mechanism of the exposure-counter window.

 

 

d) Reset the exposure-counter window to 1.

 

 

e) Expose 12 frames (until stop).

 

 

f) Reset the exposure-counter window to 1.

 

 

g) Expose another 12 frames (until stop).

 

 

Loading in accordance with the above gives relatively good spacing results troughout. In the older magazines, that is Construction 1 and also Construction 2, it must be expected that certain frames, especially in the film-section 8-12, can overlap by a few millimeters. But spacing is better in the newest magazine, Construction 3.

 

 

Regarding the loading of Magazine 16 and 16S which have manufacturing numbers below 204.200, these should be loaded in accordance with the instructions according to Magazine Construction 2; from manufacturing number 204.200 and above, according to Magazine Construction 3. In both cases, the resetting of the exposure-counter window is to be done after 16 exposures have been made."
