How to determine recommended shutter speed:
Table A: Find the number that applies to the speed of the film you are using.
Table B: Measure the length of the material being copied and the length of its focused image on the ground glass (to

determine the reproduction scale). Find the corresponding number in the table.

Table C: Decide which lens f-stop you wish to use. Find the number that corresponds to that f-stop.
Table D: Add the numbers you get from Tables A, B, and C. Find that number in Table D, and see the suggested shutter

speed.

If your total has a 1/2 in it, use the next higher full number from Table D.

Table A

Film Speed

ISO3000/36°............. 1

ISO800/30°............... 3

ISO400/27°............... 4

ISO200/24°............... 5

ISO100/21°............... 6

ISO80/20° ................. 6 1/2

ISO50/18° ................. 7

ISO25/15° ................. 8

ISO3/6° ..................... 11

With color films, adjust the
speed to compensate for filter
factors.

4X ............................5 1/2

5X ............................6

6X ............................6 1/2

9X, 10X....................8

Measure the length of the original
and its length on the ground glass
to determine the reproduction
scale.

*Filtration will be necessary for Polacolor films. See the
current film instructions for specific details.

**Includes compensation for low light-level reciprocity
failure. This compensation is an average for Polaroid

instant films in general, and thus a rough guide only. Note
that color films will require filtration in addition to a longer
exposure.

f/8 .......................... 2

f/11......................... 3

f/16 ........................ 4

f/22 ........................ 5

f/32 ........................ 6

When setting the lens
between two f-stops, use half
numbers. Thus, for f/11-f/16
use 3½.

This is intended as a guide, not a precise exposure
indicator. You may have to compensate for unpredictable
variables which affect exposure, such as brightness of
window or room lighting, differences in color or contrast of
the subject material, voltage fluctuations, or the age of the
lamps
