Windows 7 darkens photos from Canon SX10
I have a camera I like, but a problem with it. I took a few indoor photos and it took awhile to get enough light arranged for them. When I put the camera's SD card in the card reader and looked at the photos they looked great. I copied the photos to a folder then deleted everything on the card to get it ready for the next photos.

Then when I look at the photos from the desktop folder, they are much darker. I don't do this a lot but it has happened at least once before, and I think it does that all the time. Does anyone know what the problem is, or a fix for it. Can you just lighten photos with Gimp?

I did find a page that said you could, but it is probably an old page, at brighten dark photo with Gimp. It instructs me to
Quote:Duplicate the original image layer in the layers dialog. Change the Mode of this duplicated layer to Value -mode to use this layer for a retouching brightening of colors.

When I create a duplicate layer, click on image, hover over mode, none of the options are value. Maybe that was for an older version of Gimp? The page doesn't have a date which isn't nice.

Or does anyone know what the problem might be between the Canon view, and the windows 7 view? Is there something I can tweak in 7?

thanks in advance

Edit: I found it in the colors > brightness and contrast, but maybe I can leave this up in case someone knows how to stop the darkening from happening in the first place. The photo quality isn't as good as it was in the Canon folder.
