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 pro cesses 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 fo rm a so-call ed 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 ca n be te mporarily stored e ither 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.
