General overview
In very simple terms, a CF digital back holds a light sensitive sensor in place at the
film plane. The electronic signals from the sensor are then processed and stored as
a digital file.
As an electronic colour image is made up of three components − red, green and
blue which combine to form a so-called RGB image − the sensor's task is to convert a
multi spectrum light image into three digital files (red, green and blue) for combina-
tion later on.
A CF digital back uses a CCD (Charged Couple Device) type sensor that has 22 or 39
million light sensitive areas on its surface each of which creates a pixel.
Each pixel in the sensor is filtered to create the three separate red, green and blue
files. Software then processes these electronic files as a package to produce the vari-
ous formats − RAW, TIFF, JPEG etc.
The three components of the image file are later recombined on the computer screen
to produce the familiar full colour image.
The image file can be temporarily stored either in a CF digital back with a CF card,
on a Hasselblad ImageBank-II or the hard disk on a computer. Processing of these
images is carried out in conjunction with the included FlexColor software. See the
separate FlexColor manual for further details
