Introduction

The Polaroid MP4+ System is an un-

usually 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 photo-

micrography, photomacrography, copy-

ing, 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 magnifica-

tion. For even higher magnification,

the camera can be used with a micro-

scope. With its wide selection of ac-

cessories, 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 imagi-

nation 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 rever-

sal will not, of course, appear in your

picture.)

The focusing screens

The three focusing screens (9) are for

use with the Polaroid film holders de-

scribed 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 centi-

meters, to measure reproduction

size.

Introduction

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 hold-

ers also can be used with a wide vari-

ety 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 self-

cocking, lensless shutter; the lenses

are attached to the shutter, which is

mounted in a lens board, for easy cam-

era attachment. The shutter speeds

range from 1 sec. to l/125 sec., and

there is a “B” setting for time expo-

sures. 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

Film processing timer

The battery powered digital timer (13)

is designed to provide accurate timing

of film processing. It may be attached

to any convenient location on the sys-

tem.

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 bal-

ance the MP 4+ tungsten and halogen

lighting for use with Polacolor films.

Filters for other purposes may be used

also, as required. Complete instruc-

tions 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 copy-

ing 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 or-

dered 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 photogra-

phy. 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 ex-

posure 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 photogra-

phy. The system includes a 400 watt-

second 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 daylight-

balanced 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 fluores-

cent lamps; its diffusion cover pro-

duces even illumination across the en-

tire surface. A cover fits over the light

box when it is not in use. The light box

is ideal when photographing transpar-

ent 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 photomac-

rography 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

The MP 4+ System should be as-

sembled 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 base-

board. (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.

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 in-

stalled before attaching the column

to the baseboard. See the instruc-

tions 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 col-

umn onto the post (2) and secure it

firmly with the lock-ing knob (b).

Standard Model

Hold the baseboard in a vertical posi-

tion, and the column in a horizontal posi-

tion (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 pro-

vided (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, mak-

ing 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 car-

riage 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 ver-

tical 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.

Assembly

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 re-

lease: 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 cam-

era 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 spe-

cial 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 con-

venient 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 bat-

teries; 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.
