Is there support for 24 bit floats in Libtiff (Adobe Photoshop TIFF Technical Note 3)?

Yes. They will be upsampled to 32-bit floats.

I should clarify myself here. I messed up libtiff with GDAL. Libtiff, of course, has nothing to do with actual data format, it will be returned as is, without any conversions (i.e., in form of 24 bit float array).

Can a similiar conversion occure in libtiff?

If I remember correctly the LogLUV pixels are converted to 32-bit likewise. The same could apply to IEEE Half.

This would increase compatibility. Blender, CinePaint and possibly more applications will soon use at least the Half float variant much more.

kind regards
