JPEG Compression on Mavica
How the Mavica's aggressive JPEG compression shapes its distinctive image character — artifacts as aesthetic.
Why Mavica JPEGs look the way they do
Every digital Mavica saves images as JPEG files. With only 1.44 MB of floppy storage, the camera must compress aggressively — typically using JPEG quality levels around 60-75% to fit usable image counts on a single disk.
Fine vs Standard quality
Most Mavica models offer two quality settings:
- Fine — Higher quality, larger files, fewer images per disk
- Standard — More aggressive compression, smaller files, more shots
On the FD90, Fine mode at 1280×960 produces ~180 KB files (about 8 per disk). Standard mode drops to ~100 KB (about 14 per disk).
Compression artifacts as aesthetic
The heavy JPEG compression produces characteristic artifacts:
- Blocking — visible 8×8 pixel grid patterns in gradients
- Ringing — halos around high-contrast edges
- Color banding — posterized gradients in skies and shadows
- Mosquito noise — shimmering patterns around fine detail
These artifacts are now embraced by the lo-fi photography community as part of the Mavica character. They're impossible to perfectly replicate with modern cameras — the specific JPEG encoder in each Mavica model produces a unique compression signature.
BMP mode
Some Mavica models offered uncompressed BMP output. A single 640×480 BMP file is ~900 KB, consuming most of a floppy disk. The FD90 and FD200 support BMP mode, but it's rarely used due to the extreme storage penalty.
