While file format (RAF, DNG) often is an acronym, “raw” by itself simply references raw image data; it is not an acronym, not a trademark, and does not need all caps.
The mistake of “shouting” raw is perpetuated in the wild even by serious companies, but let’s not let Apple degrade our literacy[0]. I’ll point to Adobe which does, in fact, use the correct spelling[1].
