Imacon 3F

3F (short for Flexible File Format; also called FFF, Imacon 3F, Hasselblad 3F, etc.) is a raw image format produced by some Imacon and Hasselblad scanners and digital cameras.

It is based on TIFF. If you display a 3F file in a TIFF viewer that does not understand 3F, you might only get a low-resolution version of the image.

It is the predecessor of Hasselblad 3FR.

Identification
If TIFF tag 46275 is present in the first IFD, it's likely a 3F file.
