Introduction
The Polaroid MP4+ System is an un­usually versatile photographic unit. Its uses in industry, business, medicine, research, education, the graphic arts and in a vast variety of other fields are almost unlimited. They include photo­micrography, photomacrography, copy­ing, small-object photography, gross specimen photography, X-ray copying and many others.
The camera can be used with almost all Polaroid instant film types. With these, it can complete most jobs within seconds, without a darkroom. The camera also can be used with some wet-process films.
The selection of lenses, and a macro extension, render possible a wide range of reproduction ratios, from extreme reduction to high magnifica­tion. For even higher magnification, the camera can be used with a micro­scope. With its wide selection of ac­cessories, the MP4+ is much more than just a camera - it is a complete photographic system. The versatility of the system is limited only by the imagi­nation and ingenuity of the user.

Introduction 4
TTI AVl810 8x10 camera
This camera (6) may be attached to the column in place of the standard MP 4+ camera, to allow the use of Polaroid instant 8x10 films.
Polaroid 8x10 film system
This includes the 8x10 film holder and film processor (7). The film holder also can be used with other 8x10 camera systems.
The reflex viewer 44-55
This accessory (8) attaches to the ground glass. The viewer contains a mirror, which directs the ground glass image forward, rather than upward, to make viewing and focusing much more convenient. The viewing hood on the front ex-cludes ambient light, so that the image on the ground glass may be seen most clearly.
The image you see with the reflex viewer will appear the right way up, but reversed from left to right. (This rever­sal will not, of course, appear in your picture.)
The focusing screens
The three focusing screens (9) are for use with the Polaroid film holders de­scribed below. They also can be used with most wet-process 4x5 sheet film holders, and some wet-process roll film holders. They are scribed for Polaroid 4x5 sheet film and 31/4 x 41/4 pack film formats. The image area of 4x5 pack films extends from the right-hand marking to about l/8 in. (3mm) beyond the left-hand marking.
Ground glass 44-50
This is a standard ground glass screen, for general-purpose photography.
Aerial image ground glass 44-5 7
This ground glass has a clear-glass circle in the center. The image can be focused on the ground glass in the normal way, or in the clear spot as an “aerial image”. Instructions for use are supplied with this ground glass.
Calibrated ground glass 44-54
It is calibrated in inches and centi­meters, to measure reproduction size.

The film holders
The MP 4+ System can be used with the following Polaroid instant film holders (10): Model 545 film holder for Polaroid 4x5 sheet films Model 550 film holder for Polaroid 4x5 pack films MP 4+ 44-48 film holder for Polaroid 31/4x41/4 pack films Model 405 film holder for Polaroid 31/4x41/4 pack films
With the Model 405 film holder, the location of the image area is not the same as that scribed on the ground glass. For accuracy in composition, a framing template and instructions for its use are provided with the holder.
The Model 545,550 and 405 film hold­ers also can be used with a wide vari­ety of 4x5 cameras and instruments.
In addition, a number of roll and sheet film holders for wet-process films can be used with the MP4+ System.
The MP4+ shutter kit 44-60
The MP4+ System uses a self­cocking, lensless shutter; the lenses are attached to the shutter, which is mounted in a lens board, for easy cam­era attachment. The shutter speeds range from 1 sec. to l/125 sec., and there is a “B” setting for time expo­sures. There is also a flash socket with “X” synchronization. The kit (11) in- cludes the shutter, cable release, and microscope adapter. The microscope adapter is attached to the shutter in place of a lens, for photomicrography. Instructions are provided with the kit.
Lenses for the MP4+ (12)
44-65 135m m lens; f/4.5 to f/32 44-66 105mm lens; f/4.5 to f/32 44-67 75mm lens; f/4.5 to f/32 44-68 50mm lens; f/4.5 to f/32 44-69 35mm lens; f/4.5 to f/32 44-70 17mm lens; f/4 to f/22

MP 4+ Filter kit 44-88
The kit (14) includes a filter holder with two filter trays, gelatin filters and a filter frame. The filters are intended to bal­ance the MP 4+ tungsten and halogen lighting for use with Polacolor films. Filters for other purposes may be used also, as required. Complete instruc­tions are provided with the kit.
See Appendix for information about other methods of attaching filters to the MP4+ lenses.
Macro extension 44-45
The macro extension (15) is attached to the camera between the bellows and the camera head. It enables you to make photographs at magnifications up to about 27X, using the 17mm lens. You can use two extensions to increase the magnification range accordingly.
See Appendix for more information.
Universal camera mount 44-85
This accessory (16) enables you to convert the MP4+ into a 35mm copy­ing or slide-making system. The MP4+ camera head is removed, and the mount is attached to the column in its place. Virtually any 35mm camera, and many conventional cameras of other formats, can be used on the mount.
Lighting options
Several lighting options are available for the MP4+ System. These are or­dered separately, allowing the system to be customized for a wide variety of applications.
Tungsten lighting
This lighting (17) is suitable for most general purpose copystand photogra­phy. Includes four 150 watt lamps and lamp holders. The lamps are attached to the MP4+ lamp arms. 11O-l 20VAC system: 44-26 220-240VAC system: 44-36
Halogen lighting
This lighting (18, 19) is suitable for most general-purpose copy-stand photography. Includes two 300 watt lamps and lamp holders. The lamps are attached to the MP4+ lamp arms. Halogen lamps produce light of the same color temperature throughout the life of the bulb. As a result, the film ex­posure and filtration requirements are more consistent. (As tungsten lamps age, they produce light of a lower color temperature.) 120VAC system: 44-28 220VAC system: 44-38 240VAC system: 44-34
Introduction 7
Electronic flash lighting
This lighting (20) is suitable for most general-purpose copystand photogra­phy. The system includes a 400 watt­second power supply, two lamps with 150 watt modeling lights, and a sync cord. The lamps are attached to the MP 4+ lamp arms.
Electronic flash produces light that is similar to daylight, eliminating the need for most filtration when using daylight­balanced color films. 11O-120VAC system: 44-27 220-240VAC system: 44-37
XLR Baseboard light box
The Model XLR baseboard includes a well for an optional light box (21). The light box contains four 14 watt fluores­cent lamps; its diffusion cover pro­duces even illumination across the en­tire surface. A cover fits over the light box when it is not in use. The light box is ideal when photographing transpar­ent and translucent subjects. It also can be used in combination with other light sources, to eliminate shadows around solid subjects. 11O-120VAC system: 44-18 220-240VAC system: 44-19
Fiberoptic lighting
The Dolan-Jenner fiberoptic lighting system (22) is intended for photomac­rography of small three dimensional objects. The system includes a power supply with adjustable light output, a bifurcated fiberoptic bundle, a lens/ filter adapter for each bundle, lenses and filters.
The power supply contains a 21V, 150W EKE quartz reflector lamp. 11O-120VAC system: 44-25 220-240VAC system: 44-35

Location
The MP 4+ System should be as­sembled in the area where it will be used. The system should beplaced on a sturdy table or counter, large enough to provide a work surface next to the base­board. (A desk with locked storage space is ideal, to prevent unauthorized use.) The system must be located near an appropriate electrical outlet. Avoid placing the system near windows or other sources of bright light. Be sure the lamp arms do not extend into corridors.
DO NOT LET POWER CORD HANG OVER FRONT EDGE OF TABLE OR COUNTER, OR TOUCH HOT SUR­FACES. UNIT MUST BE GROUNDED. POWER CORD HAS THREE-PRONGED GROUNDING PLUG, WHICH MUST BE PLUGGED INTO APPROPRIATE OUTLET. IF SUCH AN OUTLET IS NOT ALREADY A V AILABLE, EXISTING OUTLET MUST BE CHANGED.
DO NOT, UNDER ANY CIRCUMSTANCES, REMOVE GROUND PRONG FROM PLUG.*
IF EXTENSION CORD IS NEEDED, USE CORD WITH GROUNDING PLUG* AND SUITABLE CURRENT RATING. CORDS RATED FOR LOWER AMPERAGE THAN UNIT MAY OVERHEAT. ARRANGE CORD SO THAT IT WILL NOT BE TRIPPED OVER OR PULLED. * THIS APPLIES ONLY IN COUNTRIES WITH GROUNDED ELECTRICAL SUPPLIES.
Assembly 3
Attach column to baseboard
Important: Before assembling the sys-
tem, check that the camera and column serial numbers match. (The numbers are stamped on the shipping cartons.)
Model XLR
The optional light box should be in­stalled before attaching the column to the baseboard. See the instruc­tions packaged with the light box.
Position the column post as shown, with the milled section (1-a) pointing toward the center of the baseboard. Fasten the post to the baseboard using the four nuts and bolts provided. A wrench is supplied for tightening the nuts; use a suitable screwdriver to hold the bolts while you are doing this. Slide the col­umn onto the post (2) and secure it firmly with the lock-ing knob (b).
Standard Model
Hold the baseboard in a vertical posi­tion, and the column in a horizontal posi­tion (3). The scale on the column should face toward the center of the baseboard. Insert the four bolts through the column base and then through the baseboard. Add the washers, and then the nuts. Tighten the nuts with the wrench pro­vided (4); use a suitable screwdriver to hold the bolts while tightening them.
Assemble the camera
Attach vertical carriage to column
Loosen the locking lever (5-c) by at least one full rotation. Carefully push the lower end of the carriage onto the column, making sure that the two white rollers (6-d) slide down behind the rails (e). Lower the carriage further, until the two white rollers at the top rest against the top of the column (7). Slowly rotate the height adjustment crank (f) in a clockwise direction and, as the carriage slowly goes down, make sure the white rollers feed in behind the rails, as shown. Lower the carriage by about two more inches, and lock it on the column by tightening the locking lever (8-c).
Assembly 4
Attach spring housing and counterweight spring
Insert the spring housing into the top of the column (9). The spring ends should face the front. Remove the pin (10-g) from the vertical carriage by unscrewing it and pulling it out. Unlock the vertical carriage, bring it all the way to the top of the column (11), and lock it again. Reinsert the pin, mak­ing sure that it goes through the loop
(12-h) in the spring end. Tighten the pin.
(Note: The second spring is required only when using the 8x10 camera.) Wind the vertical carriage down the column until it is at an easily accessible height (13) then lock it in position.
Warning: Never loosen or remove the spring pin unless the vertical car­riage is at the top of the column and locked in position.
Attach camera body to vertical carriage
Loosen the knob (14-i) until it is in a ver­tical position, as shown. Also loosen the screw (j) by about three full rotations. Orient the camera body as shown
(15), then push it all the way onto the
carriage (16). Rotate it back and forth slightly, until you feel it click into the true vertical position. Tighten the screw and then the knob.
Put shutter on camera
First screw the “exposure” cable release into its socket (17-k). Then align the smallest of the three tabs (18-l) on the shutter panel with the smallest of the cutouts (m) on the camera body. Push the shutter unit onto the camera in that orientation, and rotate it in a clockwise direction (19) until it comes to a firm stop. Caution: When there is no lens on the shutter, the shutter blades are exposed and unprotected. They are very delicate; do not touch them.

Assemble the sliding head
Note the orientation of the sliding head; the pins (20-n) fit into corresponding holes in the camera body.
Hook the camera head onto the left side of the camera body (21) then lower the head carefully, taking care that the pins engage in the holes on the camera body.
Lock the head in place by pushing the latch (22-o) toward the camera body.
Sliding the camera head
Depress the release button (23-p) and slide the head all the way to the right for viewing and focusing. Depress the other release button to slide the head to the left for picture-taking.
Connect the long “pre-view” cable re­lease: Do this with the camera head in the picture-taking position (pushed all the way to the left). Screw the release into the “preview” socket on the shutter
(24).
Look at the shutter from above; the shutter blades should be fully closed
(25). Now push the head all the way into
the viewing position. The shutter blades should be fully open (26). If the above does not happen, adjust the plunger end
(q) of the release until the shutter func-
tions as described. Fit the cable releases into the clamps
(27). This will prevent damage to the
shutter if the cable is accidentally pulled.
Attach lens fo shutter
Carefully screw the lens into the shutter
(28).
Attach the ground glass
One end of the ground glass frame has two small protrusions (29-r) near its base. Hold the frame in the left hand, with the protrusions pointing to the left. Slide the ground glass frame into the camera head from the left (30). Slide it all the way in, so that the two retainer pins on the frame engage securely in the two spring loops on the camera head.
Attach the reflex viewer
The pins on the sides of the viewer fit into the slots on the ground glass frame
(31).
Attach the film holder adapter
If using a Polaroid Model 545, 550 or 405 Film Holder, insert the U-shaped adapter. Orient the adapter as shown (32). Slide it all the way into the head, so the pins (s) fit under the springs (t).
Warning: When using the sliding cam­era head with heavy accessories, such as one or two macro extensions, always lock the vertical carriage on the column as soon as you have raised or lowered the camera. If you do not, the camera may begin to slide down the col-umn, due to the extra weight.

Attach the lamp arms
The two lamp arms are fastened to the left and right sides of the baseboard, near the rear edge of the baseboard.
Orient the lamp arms so the screw faces up (33), and the angle indicator faces the front of the baseboard (34).
Insert the screws into the top twoholes in the metal plate, then tighten them firmly (35).
Orient the horizontal cross bars as shown (36). With the MP 4+ Standard Model, note that distance (u) is slightly shorter than distance (v).
Attach the cross bars: Slide the cross bars into the top of each lamp arm (37). Rotate the bar until the groove (w) points down and the second groove (x) is aligned with the fastening screw. Tighten the fastening screw to lock the bar in place.
Angle the lamp arms: Angle them as indicated by the two marks, and lock them in position with the lever. This will place the lamps in the correct position for most general copying work. For spe­cial lighting requirements, the lamp arms may be angled in any way desired. The lamp arms are designed for use with various types of lighting equipment; see the instructions packaged with your lights for details on locating the lamps on the cross bars.
Attach the timer
The timer may be attached to any con­venient location, such as the front of the sliding head (38). Simply remove the paper backing from the adhesive strip on the back of the timer, and press it into position. The timer is powered by two bat­teries; if the timer stops working, or if the display or tones fade, the batteries should be replaced. To replace the batteries, slide the door open (39), and insert the new batteries in the orientation (+/-) indicated inside the compartment.
Important: After replacing the batteries, press the SET and START buttons simultaneously, to ensure proper functioning of the timer.
