    Whenever I convert an image, say from the .TIF format, to JPEG, I quickly noticed that red and colors associated with it become very blurry or "lossy." The other colors are not affected through JPEG conversion.

    Why is red and colors associated with it become blurry because of JPEG? Is there a way to correct this problem?

    prolly should be in the computer forum.

    What program do you use to convert?

    Red is probably the trickiest color to present in graphics without having it look like crap. That also goes for the video quality of red colors in everything from videotapes, laserdiscs, DVDs, mpegs, Quicktime files, etc. Whenever I design graphics and there's a good amount of red involved I make sure to increase the quality/size of the file so my reds don't look hideous. You have to experiment until you're pleased with what you see.

    Just off the top of my head it may be a color gamut problem. If you are converting CMYK .tif files to RGB .jpg (.jpg has only recently supported CMYK) files you could possibly have quite noticeable color shifts, particularly blues.
