General overview
The 16 million pixel digital back can produce 16 bit
raw files at 33 Mbytes each at a rate of 35 frames per
minute.
FlexColor then processes these files to produce the
quality expected from Hasselblad.
In very simple terms, the CFV 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.
The CFV uses a CCD (Charged Couple Device) type sensor that has 16 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 the CFV with a CF card, on a
Hasselblad Imagebank 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

The CFV is designed to fit Hasselblad V model cameras primarily. Please check the
connectivity diagram for further details about the various models, including the
possibility of connectivity to large format cameras.
