While on the topic, does anyone use 16-bit float (aka "half float") TIFF images? There's TIFF Technical Note 3 [1], but does libtiff support it? Mostly just curious as it seems most people just use OpenEXR for half-float images.

Libtiff does support 16-bit and 24-bit float in TIFF according to Cris Cox's specification. The using code still needs to know how to decipher 16-bit and 24-bit float values returned by libtiff.

GraphicsMagick supports reading/writing 16-bit and 24-bit float in TIFF even though it only uses integer storage for the samples internally.
