As part of their effort they acquired Tiff design who previously had worked on developing Canon’s CRW file format but were struggling like many others trying to make a free standard alternative for the closed RAW formats.

Greg Hitchcock was hired as project manager and Tom Hogarty as product manager to bring this new format into being with others joining later including Dave Coffin who wrote most of the code that made up … Read the rest
