Folks, This issue was already discussed several times in the past. libtiff does the right thing with 24-bit samples (as per Chris' explanation) and GDAL does the right thing too. Just search for TIFFSwabArrayOfTriples() definition and its usage. All 24-bit floating point samples from Chris work fine in OpenEV for a long time. Best regards, Andrey -- Andrey V.
