Here's something the more experienced photographers might be able to help me
with...
Among these old slides I've been scanning are a handful of colour ones which
are not part of the Australian stuff. A few of these colour ones (but not all)
appear to have a kind of halftone pattern. See here for an example at 1200ppi.

can you post a snip at 100%? the pattern as far as i can make it out doesn't
have traditional halftone angles, and appears to be RGB, rather than CMYK; this
would suggest it was shot from a display or some other transmissive, rather
than reflective, source; what that could have been in 1951 i have no idea - is
the actual slide from 1951, or is it perhaps a repro slide shot off of a video
of the original?
