FFF to DIS Conversion: FAQ

What are FFF files?

FFF is a RAW image format associated with Hasselblad cameras. This Swedish brand is well-known among photography experts and aficionados, and its history dates back to mid-1800s. Some of the most popular cameras and photographic equipment produced under the Hasselblad brand dates from during and after World War II. Hasselblad produces medium-sized cameras and in recent years it started to collaborate with Sony. The main advantage of shooting in the FFF format is the ability to apply a great amount of image editing in digital post-processing and ensuring a high quality image.
