I've just posted draft 1 of TIFF Technote 3 at http://chriscox.org/TIFFTN3d1.pdf

This technote covers improvements for floating point image data support available in Photoshop CS2.

Let me know if you see any errors, and if I need to provide more details anywhere.


This means that the predictor reorders the bytes into a semi-BigEndian order, and that the TIFF reader and writer should not change the byte order of the image data outside of the predictor.


I think I know what you mean, but it's mighty confusing. Wouldn't it serve your intention better to use the word 'bit-order' in relation to the throwing around bits scheme that serves the predictor, rather then the word 'byte-order'?

Also, possibly I'm being stupid, but I'm unsure about how the regular Intel/Motorola byte-order issue applies to the 16bit float format. Does swapping apply in such a case, i.e. is the image data differently swapped in Intel and Motorola byte order files? Perhaps a note about that could be a useful addition, if I'm not being plain stupid.
