Auto Fix Colors
Many photo-editing programs can automatically correct the colors of your digital photos. In Adobe Photoshop Elements, for example, go to the Enhance menu and click on Auto Color Correction. You'll be surprised by how effective it can be.
Find Photo Information
Can't remember when you shot a particular photo, or which camera you used to shoot it with? Just look at the EXIF—the Exchangeable Image File Format data that's recorded to every image file. It contains a variety of info and can be read by most imaging software.
Convert RGB to CMYK
Ever wonder why your inkjet photo printouts don't match the colors you see onscreen? It's because your computer and printers are probably using different color descriptions. For better results, try converting your photo from RGB to CMYK, a color description your inkjet printer will recognize. Most photo-editing software will let you do the conversion.
Always Duplicate
Before you do any photo editing, create a copy of the image. That way, you can always return to the original if things go awry. Trust us: This will save you a lot of headaches in the long run.
