- Each RGB component of a pixel is stored as 8 bits (a color intensity can be represented on a scale from 0 to 255)
- It uses lossy compression (to save space, the image is compressed at the cost of lost information (artefacts such as approximations and tiling)
(- No camera meta data)
A RAW file usually uses 14 bits thus a color intensity can be represented on a scale from 0 to 16384.
The format is usually losless as well.
One could use jpeg images to produce HDR images. However, to mitigate the limitation of 8 bit representation (and compression artefacts), one would need more images to work with (and it would also depend on the quality of the software used of course).
