3.2.4 Camera parameters
The settings in this tab affect the camera rotation, the vertical image format and the light
metering. Any change will be applied starting from the next scan.
Press the „Camera parameter“ button in the „Parameter“ menu to activate
the „Camera parameters“ tab:
The tab contains the following options:
Return to start: force the camera to return
to start from the same path as image scan.
This is necessary for pixel-exact merging of
multiple images (when combining several
images by shifting or for HDR)
Take picture CCW: scan the panorama in
the opposite direction(it is necessary to
rotate the digital back upside-down)
Pause after prescan: after making a
prescan, the camera stops at starting
position. When the button “resume” is
pressed the image scan is done directly
using the previous exposure measurement
Variation with manual exposure: after
taking an image using a fixed exposure
time, it is possible to edit an exposure
correction curve overlayed on the image.
The image exposure time will vary within a
single image according to the defined curve
Variation parameter: defines how fast the exposure correction can be done. A small
value gives a smooth adjustment, a strong value gives a sharp adjustment.
Pre-angle: sets a pre-rotation (without image taking) before the actual image
capture
Measure angle: defines the horizontal angle for automatic light metering. Please
note that for automatic exposure (pre-scan) the camera creates a pre-scan for exact
light metering
To combine several images either for multiple HDR or for shifting /
stitching it is necessary to force the motor back by a counter-clockwise
rotation (option: “return to start”). This allows are very precise pixel
registration and easy merging.
