Technical note

FIT to WEBP: what to expect from the conversion

A scientific camera records 32 bits per pixel, and the signal of interest often occupies a narrow slice of that range, while WEBP shows 8. Conversion applies a display mapping, so two acquisitions that look identical afterwards can hold very different underlying intensities. Treat the WEBP output as something to look at and publish rather than something to measure. FIT stores pixels without compression loss and WEBP does not, so this is a one-way step. Choose a high quality setting, and avoid converting the same file back and forth, because each pass compounds the artefacts.
