I �m dealing with new JPEG in TIF images. I have implemented the JPEG support for TIF, but the resulted image is one that has different colors in comparison with the original image.
Most likely you either (a) got the channel order swapped (eg, BGR instead of RGB), or (b) messed up YCbCr=>RGB conversion (omitted it or did it twice).
