- Actually, all the above is true, except for the "session" size. Basically,
- a session is however many images you have available for recording at one time.
- Meaning, if you shoot 3-36 shot rolls of film and send them all in at once,
- you can get all 108 images in one session. Also, under these circumstances
- you can probably fit 108 images. There's a capacity loss involved in writing
- each session, and there's some variability in the compression used in
- making the PhotoCD format, but it's possible to get as many as 120 images
- on a single-session PhotoCD.
