There's also RGBE (4 bytes per pixel, the last one stores an exponent
value indicating the magnitude of the pixel), and LogLUV TIFF encoding.

There's also XYZE (like RGBE, only with the XYZ color space...which I
don't know anything about), some more HDRI TIFF formats, and PFM
(Portable Float Map).
And I think someone else had a working HDRI output patch...
