SFW – Maximum bits: 24

Seattle FilmWorks SFW format is a variant of the standard JPEG/JFIF format that was apparently "invented" to force users of their digitized photo service to use only the Seattle FilmWorks supplied viewer. It differs from the standard format in very minor ways – the encoding and compression data format is identical. SFW image files contain 24 bit per pixel images.

GFX-View V3 cannot save Seattle FilmWorks SFW format.
