Re: R: March 2002 PUG Comments (and a Question)
That is not entirely correct. Win 98, and I suppose newer versions, can use color profiles for the system. I am certainly using one now. Go into display setting, advanced, color management. One of the strange things is, if you are using color management for the system, you have to turn it off in your picture editing software. AND, you need to set the gamma in you picture editing software to 1 as gamma correction is already done by the system color management.

Fabio, Do you use a browser to view the photos before you send them. I've found there is often a slight difference in how my pictures look when I view them with photo imaging software (gimp or photoshop) and browsers. I don't know why this is but if I had to make a guess I would think it probably has something to do with how they read the jpg compression. Maybe someone with more technical expertise can shed some light on this. Evan Thank you Ed but the scanned image I sent wasn't so dark! My pictures on the PUG are *always* darker and/or more satured than the pics I submit. Does anyone know what can I to do to avoid it?
