There are a number of reasons why using film might either be preferable or even necessary. For ex-
ample you might want the specific results you know that a certain film emulsion can produce or you
might want to use very long exposure times, etc. Don’t forget that 6 x 6 cm film magazine use will
also allow you to exploit the full focal length of your lenses.
As a rough guide, the following are some items regarding film use that differ from digital back use.
Please see the film magazine user manual for full operational details.
Infrared photography with film
Infrared (IR) rays (wavelengths longer than 800 nm) form an image on a plane further
away from the lens than the image plane for visible light. To compensate for this differ-
ence you have to align the chosen distance against the red IR index and not the normal
central index. Proceed as follows:
1. Focus as usual on the focusing screen.
2. Note the distance on the focusing scale that is opposite the central index line.
3. Now rotate the focusing ring to set this distance opposite the dashed IR index line
instead of the central index line.
Please observe the special information that came with your IR film regarding magazine
loading, film development, etc.
Double exposure with film
Double (or multiple) exposure is possible with a film magazine. However, as the camera
has been designed to prevent accidental double exposure you will have to carry out the
following procedure in order to make multiple exposures on the same frame:
1. Make the initial exposure.
2. 1nsert the magazine slide and remove the magazine.
Film Magazine Use
The 503CWD also accepts film magazines allowing
for greater freedom and versatility.
