Model pop-up menu before you start taking pictures for the first time and
each time you change the type of camera body that you are using with the
camera back.
To set the Model list to show only cameras compatible with your current
camera back, mark the Show recommended only check box.
If you are using an unlisted camera body, then chose Generic. In this case,
you may need to experiment a bit with the Shutter delay setting to
optimize your results (see below).
Shutter Delay
When you click on the Capture button in FlexColor, a short amount of
time elapses between the moment you issue the expose command and the
moment the flash is fired. The camera body needs to allow some time for
its internal mechanics to, for example, move the mirror and open the
shutter. FlexColor must know this time so that it can correctly
synchronize the shutter, flash and CCD exposure.
The shutter delay time is different for each camera back model. The delay
is set automatically when you choose a camera body from the Model
pop-up menu. However, you must set this manually when you choose the
Generic setting.
NOTE! Even when working with a specific camera body, you are able to
adjust the shutter delay time manually if necessary. The value is resettable
by clicking the Default button.
Under normal circumstances you simply choose the preferred camera
from the drop down menu. You could however experience that your
camera does not perform correctly using the default shutter delay, causing
colors to slide or other unwanted effects. This is due to a timing error in
the camera different from the factory setting.
To correct this you are enabled to alter the default shutter delay settings. If
you experience problems start by increasing the delay quite a bit, for
example 100 ms. Then decrease the shutter delay in small steps until your
image looks right. This way you will find the correct synchronization for
your selected camera.
