 ## Other formats (CBF and TIFF)
-In addition to HDF5 format, Jungfraujoch allows to save images in the Crystallographic Binary File (CBF) format. 
-CBF files are written according to miniCBF format, with only basic header, and always with 32-bit signed integer format. 
-Dynamic range is reduced to max 2^24, negative numbers are zeroed, and masked, and/or bad pixels are set to -1.

-Also writing to TIFF files is possible, though no metadata are saved in this case.
+Earlier versions could also write Crystallographic Binary File (CBF, miniCBF) and TIFF images. These
+writers have been removed: Jungfraujoch now writes only NXmx HDF5. The `CBF` and `TIFF` values are

 ## No file option(s)
