The Polaroid Pack Film Back has been developed for use with the Zenza Bronica cameras, Models S, S2, and S2A.

This film back has been developed in cooperation with the Polaroid Corporation and increased the range of interchangeability in film backs, in addition to the 6x6 cm and 6x.5 cm film backs, thus giving the user greater flexibility in photography, as well as a means for checking lighting and exposure before actual picture-taking.

Read before Using the Polaroid Back

Please study this manual carefully before actually taking any pictures with the Polaroid Pack Film Back.

As you read the instructions and look at the pictures, practice the motions without actually using film. Load the film pack only after making several practice runs and when you are sure that you have got the simple operating procedures down pat.

It is suggested that you start with the black-and-white film. Always read the instruction sheet packed with the film, as these instructions may often change, in keeping up with improvements made in the film. Following are seven helpful hints towards taking better pictures with the Polaroid film pack back:

  1. Set exposure correctly
  2. Move in as close as possible, for getting a bigger image in the print
  3. Choose colorful subjects, when using color films
  4. Choose the right background, especially for flash shots.
  5. Pull the tabs correctly
  6. Time development carefully
  7. Always check the temperature

Important

  1. Always hold the camera body, when the Polaroid Pack Film Back is attached, and never hold the film back itself.
  2. The Bellows Attachment cannot be used when the Polaroid Pack Film Back is attached to the camera body.
[page 1]


Attaching the Polaroid Back

Remove the regular film back from the camera body. Insert the protruding open hinges on the lower end of the rear camera body into the connecting holes on the polaroid back and press the upper part of the Polaroid back firmly against the rear of the camera body. Move the on-off lever on the Polaroid back towards ''C'' (for close) and the Polaroid back will be connected securely to the camera body. The Polaroid back must always be connected to the camera body before the shutter is charged or, in other words, after the shutter has been released.


Moving the on-off lever to ''O'' (for open) will permit the Polaroid back to be removed from the camera body. Differing from the regular Bronica film backs, the Polaroid back is not removed by inserting the dark slide, and, therefore, the Polaroid back must be removed with the on-off lever after inserting the dark slide.

On the other hand, the dark slide must be removed for taking the picture, as the shutter cannot be released otherwise.

Films for the Polaroid Back

Three types of quick-loading Polaroid pack films are presently available for use with the Polaroid pack film back developed for use with the Models S S2 and S2a Bronica cameras. The Polaroid packs produce eight prints measuring 8.5 x 10.5 cm but since the Bronica cameras have a format of 6 x 6 cm only, the actual image area will measure 6x6 cm within the 8.5 x 10.5 cm print area, as in the specimen shown on page 9. Color prints are obtained with Polaroid Polacolor type 108 Land pack film, which has a film speed of ASA 75 (DIN 18), while black-and-white pictures are possible with Polaroid type 107 Land pack film, which has a speed of ASA 3,000 (DIN 36). Should you also require negatives, in addition to the black-and-white prints, there is a Polaroid Type 105 Land pack positive/negative film which delivers eight shots of both. Film speed of Type 105 is ASA 75.

[page 2]


Opening the Pack Film Package

Open the pack film box and, in addition to the film package, there should be a tube of coater, in the case of the black-and-white film, or a set of print mounts, in the case of the color film, which should be put back into the box once more for safe keeping.

Remove the film package only, taking care to hold it only by the edges or corners. Do not press on the middle of the film package, as you may ruin one or two prints.

Tear open the entire side of the film package, along the dotted line, and it will be possible to take the pack film out of the package. The pack films should also be handled similarly, or, in other words, by only holding them along the edges or corners.

Take out the bag of silica gel, which is packed with the color film, and throw it away.

Read the instruction sheet carefully so that you will be able to develop your prints correctly. Save the box for carrying prints safely.


Loading the Pack Film

Always load the pack film in the shade and not in direct sunlight, to avoid fogging the film.

The pack film should be loaded, if possible, with the Polaroid back removed from the camera body.

Opening the Polaroid Back: Hold both ends of the wire latch and pull in the arrow-indicated direction. The front plate should pop up slightly.

Inserting the Pack Film: Open the front plate all the way. Next, hold the pack film by the edges, with the printed surface of the safety cover (film face) towards the camera, insert the pack film into the guide frames and push down in the arrow-indicated direction.

[page 3]


Press the pack film against the Polaroid back which will nest it correctly in position.

Check the White Tabs: Check whether the white tabs, under the black tab, are free and not folded under the pack film.


Closing the Polaroid Back: Press the front plate strongly against the rear cover and fix them securely with the wire latch, as illustrated. The black tab of the safety cover should be sticking out of the small slot (white tab slot), when the front plate is locked. If not, reopen the Polaroid back and lead the black tab out into the slot.

Removing the Safety Cover: Grip the black tab firmly with the thumb and forefinger. Pull the black tab (safety cover) all the way out of the Polaroid back. Pull out straight, in order not to rip the safety cover. The safety cover can be discarded.

[page 4]


A white tab should stick out of the small slot (white tab slot), when the safety cover is pulled out. Do not pull the white tab as yet, however, as it is only an indication that the pack film has been loaded correctly and that everything is ready for taking the first picture.

If No White Tab Sticks Out

If there is no white tab sticking out, after removing the safety cover, this must be corrected before proceeding any further. The correction should be made in the shade or indoors and not in direct sunlight.


Open the Polaroid back slightly and, without disturbing or removing the pack film, push the end of the white tab out into the open.

Close the front plate securely, by pressing on both sides strongly, with the white tab sticking out of the small slot, and fix the wire latch securely.

[page 5]

Setting the Correct Exposure

It is recommended that the exposure meter or, preferably, the TTL Exposure Meter be used for determining the correct exposure. Polaroid Land pack films Types 105 and 108 have film sensitivities of ASA 75, while Type 107 has a film speed of ASA 3,000, which should be set to the exposure meter or TTL Exposure Meter when taking an exposure reading. If there is no setting for ASA 75 or ASA 3,000, as the case may be, set the film speed scale to the closest setting, or ASA 64, in the case of Types 105 and 108 film, and ASA 3,200, in the case of Type 107 film.

The following table will serve as a general guide for average subjects in bright sunlight or bright open shade, should you have no exposure meter for taking an exposure reading:

Standard Exposure

Type 107
  Subject in bright sun (EV 20)           1/1,000     f/32
  Subject in bright open shade (EV 17)    1/250       f/22

Type 105 and 108
  Subject in bright sun (EV 14 - 13 1/2)  1/125       f/11
  Subject in bright open shade (EV 12)    1/60        f/8

NOTE: In the case of Type 107 film, with subject in bright sunlight, use the Bronica ND4x filter, for obtaining a setting of 1/500 second and f/22. (Read the following explanation on the use of ND filter.)

Neutral Density Filter

The ND, or neutral density, filter is used to reduce the volume or intensity of the light coming through the lens to film, creating the same effect as obtained by stopping down the lens diaphragm, without, however, changing the depth of field effect.

The ND filter is therefore used to limit or reduce the light when there will be overexposure, when taking pictures outdoors in the bright sunlight, even with the fastest shutter speed and the smallest lens opening combination.

The use of the Bronica ND4x filter lets you use an ASA film speed setting 1/4th the actual sensitivity for the taking exposure measurements, as in the following case.

Example: Type 107 film has a film sensitivity of ASA 3,000, but when used with the ND4x filter over the lens, can be used at ASA 750 (3,000 x 1/4= 750) for taking an exposure reading, without further adjustments required in the reading thus obtained.

Picture Taking Procedures

Load the required Polaroid land pack film in the Polaroid back, following instructions on pages 3 to 5.

Attach the Polaroid back to the Bronica camera, model S, S2 or S2a, as the case may be, following instructions on page 2.

Then,

  1. Determine the correct exposure setting for the subject.
  2. Wind the film winding knob until it stops. Although the film winding action will not take place, the shutter will be charged. (Do not use the crank).
  3. Draw out the dark slide from the Polaroid back.
  4. Depress the shutter release button, when satisfied with the focus and composition of the subject.

(Refer to the quick guide of seven helpful hints on page 1, too.) You are now ready to process or develop the print.

[page 6]


Developing the Print

Grip the White Tab: Hold the Polaroid back, with your left hand, so that it is pointing straight ahead. Then, grip the white tab with the thumb and forefinger of the right hand.

Pull out the White Tab: Pull the white tab straight out, until it is completely out of the Polaroid back, and then discard it.


Let the Yellow Tab Appear: Pulling out the white tab, as above, opens a narrow door on the right-hand end of the Polaroid back, and causes a yellow tab to appear. Therefore, this side door must not be prevented from opening, when pulling the white tab.

If no yellow tab appears when the white tab has been pulled out completely, stop further action and correct the mistake, as explained on page 9.

Never pull a white tab when a yellow tab can still be seen. If you do so accidentally, stop further action and correct, as explained on page 9, too.

Grip the yellow tab: Pulling the white tab as above, does not start development, which always takes place outside the Polaroid back. The white tab is simply pulled out to place the yellow tab in position for the next step, which is pulling out the yellow tab itself. Therefore, grip the center of the yellow tab firmly with the thumb and forefinger of the right hand.

[page 7]


Pull out the Yellow Tab: Pull the yellow tab straight out of the Polaroid back, moderately fast, in one smooth uninterrupted action. Development starts when the yellow tab has been pulled completely out of the back and, therefore, start timing development from that point. A ''moderately fast'' pull should take about as long as it takes to say the words ''PULL IT'' at normal talking speed. If the developed print is full of white specks, slow down a little, as you are pulling too fast.

Let the Print Develop: Development of the print takes place outside of the Polaroid back, when the yellow tab has been pulled out completely. Therefore, let the picture develop for the full time recommended in the instruction sheet. While waiting for the print to develop, hold it by the yellow tab or place it on a flat surface. Don't touch or bend the print, or peel off the white paper. Don't let the print flap in the wind outdoors.


Separate the Print: After the recommended development time, quickly strip the white paper (print) off the brown paper, starting from the end nearest the word ''PULL''. Although the color print will appear to be nearly dry, do not touch the print for a few minutes. When completely dried, mount it on a color print mount.

Coat Black and White Prints: Do not touch the face of the black-and-white print, too. The prints must be coated to prevent fading and to add a glossy finish. See the instruction sheet for further information on coating.

The negative, from which the print has been stripped off, should be folded with the moist surface on the inside, to prevent contact with the chemicals still on the surface. The negative should then be put in a paper bag, box and/or discarded into proper waste containers. Do not throw the negatives away indiscriminately.

Do not coat color prints.

[page 8]


Let the Coating Dry: After coating the black-and-white print, do not touch the print face until the coating has completely dried up.

Polaroid prints taken with the Bronica camera cover a 6x6 cm area within the large print area, as shown on the right.


If Yellow Tab fails to appear upon pulling white tab

Do not pull another white tab. Instead, open the front plate slightly so that a finger can be inserted to hold down the pack film and keep it in place. This operation should, of course, be done indoors or in the shade and never in bright sunlight.


While holding the pack film down with one finger, open the Polaroid back all the way and take a firm grip on the topmost yellow tab, with the free hand.


Draw the yellow tab completely out of the pack film and discard it. While the Polaroid back is open, check the rollers and see if they are clean.

If a white tab has been drawn out accidentally, while the yellow tab was sticking out, then draw out the yellow tab and discard it, at this time.

[page 9]

Close the Polaroid back after confirming that the next white tab is sticking out of the small slot.

When closing the Polaroid back check that both sides of the front plate are securely locked with the wire latch.

Temperature is Important

Cold and heat have a great effect on the way your picture develops and on the print quality. Even moderate cold can ruin your pictures unless you take precautions. The important factor is the temperature of the camera and film at the time you are developing the picture.

A loaded camera carried outdoors in cold weather for half an hour gets thoroughly chilled. If you then enter a warm house and a few minutes later shoot a flash color picture, you cannot produce a good print. It takes a long time to warm up the cold camera and film.

However, if camera and film are kept warm indoors, you can snap children in the snow outside, pop back and develop the picture normally.

In cool weather, development times may have to be adjusted according to the temperature. The instruction sheet with each film pack contains detailed information about development times and temperatures. Be sure to read these recommendations; they may change from time to time.

In very hot weather, chemicals may come out of the edges of the picture assembly as you pull the yellow tab to begin development. If these chemicals collect on the steel rollers, they can cause defects in your prints. So, when it is hot, be extra careful to keep the rollers clean.


When Temperature Affects Type 108 Color Film: The normal developing times for color film are set for temperatures of 75 degrees F (24 degrees C) and warmer. When it is a bit cooler, the action of the developer chemicals slow down and you must develop for a longer time. See the film instruction sheet for more details. When the temperature gets below 65 degrees F (18 degrees C), the chemical action is so sluggish that the picture will not develop properly without help. The help is the Cold-Clip (see page 11). This is sold separately at camera shops. Prints developed in cold weather without the Cold-Clip will be dark, with muddy colors.

Whenever it is cool enough so that you must wear warm clothes, use the Cold-Clip for all color pictures. If you feel temperature is pleasant when you are lightly dressed, make development in normal way.

When you are sweltering and can think only of a cool drink and a swim, it may be too hot for best results with color film; your prints may show weak colors. For details, see the film instruction sheet.

Effect of Temperature on Type 107 Black and White Film: Best results are obtained with the film's normal range of development times in temperatures of 59 degrees F (15 degrees C) and above. When the temperature of film and camera are both below 59 degrees F (15 degrees C), develop for longer-than-normal time. Read the instruction sheet for full particulars. Never use the Cold-Clip with Type 107 pack film.

[page 10]


Using the Cold Clip

The Cold-Clip is used only for development of color prints, when the temperature is below 65 degrees F (18 degrees C).

If you are not sure of the temperature, use the Cold-Clip, as no harm will be done even if the temperature is somewhat higher than 65 degrees F (18 degrees C).


To use the Cold-Clip, put it in a warm inside pocket about five minutes before taking the picture and preheat it with the body temperature. If the temperature should be near 32 degrees F (0 degrees C), put the Cold-Clip between the arm and body which will heat it to the maximum temperature.

Double the exposure for your color pictures, if it is cold enough for you to consider using the Cold-Clip.


Immediately after pulling out the yellow tab and starting development of the print, place the developing film in the Cold-Clip, with the yellow tab section extending out. The film must be inserted between the Cold-Clip within ten seconds.

The Cold-Clip should then be put in an inside pocket, if the temperature is above 41 degrees F (5 degrees C), or between the body and arm, if it is below that temperature.


The film should be developed for 60 seconds in the Cold-Clip (in the above condition) and then removed, with the print stripped off the negative paper in the usual manner.

The Cold-Clip should be placed in an inside pocket once more, in preparation for the next picture.

[page 11]


Cleaning the Rollers

Dirty rollers will cause troubles, such as spotty development and/or blockage of the yellow tab which will then be unable to protrude. Dirty rollers are caused by developer chemicals sticking to the rollers and to the inside of the rear cover and, therefore, the rollers should be checked, whenever new pack film is loaded, and cleaned, if necessary.

Rollers can be cleaned even when the Polaroid pack is loaded.


Lift up the red-colored latch, which will permit the roller assembly to be detached. Detach the assembly and check the rollers carefully.


First, wipe the rollers with a damp cloth, then, follow with a dry cloth. Wipe until clean and never scrape the rollers with metallic articles or with your fingernail.

At the same time, open the slot door for the yellow tap, and clean the slot opening, as well as the region around it.


Use an air-blower and clean out the inside of the rear cover, before returning the roller assembly to its place.

[page 12]

Possible Picture Faults


Nearly black image or solid black: If you cannot see an image at all, the film was not exposed. You may have neglected to pull out the dark slide on the Polaroid back or the black safety cover from the film pack. Or, perhaps the shutter did not open. If the print is very dark, increase the exposure.


Very light Image or None at all: The film was either greatly overexposed, or it was accidentally fogged. Make sure the dark slide on the Polaroid back is inserted when removing or attaching the back.

Both black-and-white film and color film will be fogged if you pull out the safety cover before putting the film pack in the Polaroid back, or if you remove a film pack from the back after having pulled the safety cover.


Undeveloped edges or corners: These are usually caused by pulling the yellow tab out at an angle. In this example, the tab was pulled down instead of straight. When this happens, the developer is not spread evenly over the picture, and thus edges and corners may not develop. Always pull the yellow tab out straight and swiftly, all the way.


Broad streak: If you have one or more of these streaks running across the short width of the picture, you stopped or slowed down while pulling the yellow tab to start development. Always pull the film out in one smooth and uninterrupted motion.

[page 13]


Many Small White Specks: These are a sign that you pulled the yellow tab too swiftly. Try to pull it a little less rapidly.


Orange-red marks along edge: Reddish-orange marks like these along the edge and/or in the corners of the print (with color film only) generally indicate that the yellow tab was pulled out of the Polaroid back at an angle. Always pull the yellow tab out straight and smoothly, all the way.


Muddy looking print: The picture was not developed long enough. Develop both black-and-white and color films for the full time recommended in the film instruction sheet. See page 11 on how to use the Cold-Clip with color film. Underdeveloped color prints tend to be a brownish pink.


Oblong area in Print: The oblong area, which will be pink or red in a color picture, indicates that you did not pull the white tab all the way out of the Polaroid back. As a result, when you pulled the yellow tab, the white tab was pulled back into the Polaroid back, thus spoiling your picture. Always pull the white tab all the way out of the Polaroid back.

To: Bronica List Members

For the Bronica S2-A Polaroid back:

Any standard Pack film of the peel off variety ( 3 1/4 x 4 1/4) size should fit that back.

In the recent past I Have used #669 (Color) and #667 (Black and White), but I am sure there are other types too.

That back is a great accessory and I have had much successful use from it.

It will also fit S-2 cameras and possibly the old S model as well, but not the Z or Deluxe.

I also use Fuji FP-100C (color) and FP-100B (B&W) as it provides much better colors and blacker blacks and whiter whites than the Polaroid instant film in my opinion.
