From Brian Skiff...

On tonight’s astro-ph preprint listing is a paper by the JWST team describing the first set of publicly released data. Yes, there are now very many papers analyzing the data by folks all over the planet, but this is a description of the source data
and their processing:

The JWST Early Release Observations

Among other things, they describe various instrumental artifacts and how they are corrected. Perhaps of most interest to folks on the list is section 5 of the paper, where they outline how the raw images were turned into slick-looking publicity shots,
basically taking the peculiar mid-infrared images and making them resemble (more-or-less) the visible-light images one is accustomed to, and the aesthetic decisions involved. Specific software (some of it commercial) is cited.
