- Use an organizing program, such as Adobe Bridge, Adobe Lightroom, Aperture, or iPhoto, to manage large numbers of photos.
- To print for exhibition purposes, aim for a resolution of 240–360 pixels per inch. Check the recommendations for the printer and the paper you're using.
- Use the histogram on your camera and adjust exposure to avoid clipping of shadows or highlights in your image.
- Avoid using the sRGB color space because it loses some color information.
