During the years, there has been a lot of noise regarding Hasselblad’s .fff and .3fr files. Easy to find discussions on the Web. Best “solution” – or at least best way to circumvent the problem – seems to be to rename .fff to .tiff
For those wanting to test themselves, here is an official source for .3fr and .fff images: https://www.hasselblad.com/learn/sample-images/
Viel Spaß!
