For Your Files

David tells us that for standard 4x6 prints, 3 to 4 megapixel cameras will do an excellent job. These cameras are usually priced between $300-$500 and can produce very fine quality 8x10 prints.

David also said 80% of digital photos are processed on ink jet printers. If you are going to do that, remember two things:

  • Use good quality paper. A high quality glossy photo paper can produce a rich, colorful image. Printing it on standard 81/2x11 bond paper is going to look pretty dull.
  • Remember to look for the word "archival" on ink. Light and humidity can damage color prints, but keeping them behind glass can help protect them.
