A little perspective
James Webb Space Telescope raw exposure vs RAW photo: data size comparison
The raw-exposure data volume of a James Webb Space Telescope raw exposure is about 3.33 times the data size of a RAW photo.
BYTES OF DATA
A James Webb Space Telescope raw exposure is the unprocessed digital data captured by one of the telescope's detectors during an observation.
An unprocessed digital image file captured directly from a camera sensor, preserving original detail.
Measurements, assumptions & sources +
James Webb Space Telescope raw exposure
Defined raw-exposure data volume: 100 MB; defined data model; range 20 MB–500 MB.
A defined 100 MB raw-exposure scale for one JWST detector product. Instrument, readout pattern, groups, integrations, compression and processing level change the stored volume.
Defined examples — our methodology
The marked defined raw-exposure data volume is calibrated. Unmeasured illustration details are representative.
RAW photo
Data: 30 MB; example.
A chosen 30 MB camera RAW file. Camera and compression mode matter.
Defined examples — our methodology
The marked data is calibrated. Unmeasured illustration details are representative.

Why this measurement?
Why we use 100 MB
We compare the raw-exposure data volume of a James Webb Space Telescope raw exposure. This is an illustrative comparison value, not a claim that every example is the same. The recorded range is 20 MB to 500 MB.
A defined 100 MB raw-exposure scale for one JWST detector product. Instrument, readout pattern, groups, integrations, compression and processing level change the stored volume.
