Here’s an interesting little routine I figured out in PS CS, most likely a bug, which results in an ever darkening GIF file image. Here’s how you do it:
1. Create a new Greyscale image. Draw some stuff in there, use different tones of grey as you wish.
2. Save this as a GIF file.
3. Close the file, and reopen it.
4. Check the colour mode – PS thinks it’s a standard palletised image rather than a greyscale one. Convert the image to greyscale again.
5. Resave the image, close and reload it. It has now magically darkened for no reason whatsoever.
Hooray. I love the Adobe CS apps. A new bug each day! 😉
Addendum: It would seem that ANY greyscale GIF is automatically receiving a darkening. Also, my colour profile setup is set to not do anything fancy to Grey or RGB images (only CMYK). I might try switching colour management entirely off and see if that makes any difference. At the moment, it does appear to be something misbehaving though, as only greyscale GIF files seem to be affected.
