Available compression levels
The PDC-3000 offers three picture compression levels and a
no-compression setting. Each level uses a different method to
process the image data, providing several choices of image
quality and storage requirements:

Comp off Best 15 30
No loss 2:1 Best 30 60
Lossy 5:1 Good 75 150
Lossy 10:1 Fair 150 300
Storage space requirements for all compression levels except
"Comp off" (no compression) vary according to picture
scene. For this reason, storage space requirements and images
per CompactFlash card presented above are typical.
For the highest quality images and efficient use of storage
capacity, the No loss 2:1 setting is recommended. This
compression mode reduces the storage requirements for each
image while reproducing the original digital values with 100-
percent accuracy. The Lossy 5:1 and Lossy 10:1 compression
modes dramatically reduce storage requirements, but they
