ProPack Camera
Taking The Picture
The shutter release in the ProPack works the same as the shutter release in Reporter and EE100
cameras. When the shutter button is pressed, it closes switch S1, initiating the electrical se-
quencing. Mechanically, the shutter release pushes down on the capping blade arm and the
capping blade swings upward, out of the optical path. At the end of its movement, the capping
blade closes the flash switch (S4), releases the opening blade, and the film is exposed. When
enough light is measured by the photocell, the closing blade is released by the magnet and the
exposure is complete. As the shutter button is released, the three shutter blades return to their
original position.
Electronic Shutter
As mentioned before, the ProPack has an electronic shutter run by two 1.5 volt alkaline batteries.
The shutter operates much as the shutter in the Reporter and EE100. Shutter blade operation and
flashcube indexing is exactly as before.
Electronically, the ProPack has been modified to accept an electronic strobe called the ProFlash.

Other Similar Features
Other features of the ProPack which are similar to the Reporter and EE100 are:
—
a lighten/darken control on the shutter trims exposures from
- 0.8 stop to + 1.0 stop.
—
a heavy duty neck strap allows the camera to be comfortably carried.
—
a tripod socket in the bottom of the camera body which accepts most tripods.
—
a threaded cable release socket on top of the shutter housing permits the use of a
remote shutter button.
—
a ring handle on the door which is used to hold the camera when film is being
pulled through the spread system. The ring handle folds away into a recess in the
door when it is not being used.
NEW FEATURES:
An inspection of the ProPack shows that there are some subtle differences and some striking
differences between this camera and the earlier Reporter/EE100.
Electronic Flash Capability
The most important difference between the ProPack and the earlier cameras is the ability of he
ProPack to interface with an electronic strobe called ProFlash. (The ProFlash is covered in a
