Right - if it is stored as 12 bit samples without any padding (to fill
out to 16 bits per sample) then PS won't open it directly - Photoshops
"Photoshop Raw" importer only supports samples that 8 or 16 bits deep
exactly - I found this out recently as I was delivered a set of old
10bit radiographic images (raw data - no headers, just raw 10bit
grayscale samples) along with an ancient app to read them... but the
app wouldn't export the full rez, just a low-rez tile... so I had to
write a script to reformat the image data into 16bit samples, which
Photoshop handily opened.
