What can make a photograph last a long time?

To ensure a photograph lasts a long time, it should be printed on high-quality, acid-free paper using archival inks that resist fading. Proper storage in a cool, dry environment, away from direct sunlight and humidity, will also help preserve the image. Additionally, using protective frames or albums can shield the photograph from physical damage and environmental factors. Lastly, digitizing the image provides a backup that can be preserved indefinitely.
