There is an error in "tif_luv.c" in function Luv24fromLuv48 line 997:

Where:

     Ce = uv_encode((luv[1]+.5)/(1<<15), (luv[2]+.5)/(1<<15),

Should be:

     Ce = uv_encode((luv3[1]+.5)/(1<<15), (luv3[2]+.5)/(1<<15),

BTW, does anyone know if this format is still used for HDR images?

Best,

scuri
