3. Tips and Resources
3.1 Film spools
Always use identical film spools for non-exposed and exposed film, as different brands have different spool
dimensions.
3.2 Panorama images
In FAST mode at shutter speeds 1/500 to 1/60 hand-held shots are possible. To do this, hold the engine and control
unit firmly in your hands above your head as to avoid to be in the picture.
For shots on a tripod place the camera on the 3/8'' mount on the tripod. To avoid to be in the picture choose slow
shutter speeds or use the 10 second timer.
3.3 Length of film and number of panoramas per film
The number of possible shots with the 28-220 camera are displayed in the following table. We recommend using a
larger degree of the panorama than actually necessary (for instance 405° for a 360° shot). This allows to choose the
best section of the image later.
