Long ago in this very galaxy people used to imprint photographic images chemically on roll of something called film. These rolls were generally limited to 12, 24, or 36 images each. 36 photos is roughly 144MB of digital storage today. So, film was a very low capacity storage medium. An 8GB card today is roughly equivalent to 50 to 60 rolls of film with 36 photos per roll. If you shoot in RAW mode, well, that’s a different story. As soon as a roll was full, you would run down to someplace to have the film developed. Typically, it was your corner drugstore. You’d generally wait a few days (until one-hour processing arrived) and then finally see photos (most of which you had already forgotten about).
