These look fishy to me. But I guess I could just look at
them as if
they were Jerry Uelsmann pix.

I find it interesting that the wheel has once again been
re-invented. Multiple exposures, with and without masks, cut
and paste, etc, are all as old as photography itself. The
term "cut-and-paste" comes from the common practice in
photomechanical reproduction of making the master by cutting
and pasting the various elements, i.e., text, line drawings,
photos, which were to appear on the printed page. These
originals were usually called "paste-ups". In half tone work
the emulsions of the process plates were often floated off,
cut and assembled on a final plate for exposing the cuts.
In motion pictures the use of "matte shots" is common.
One of the first ways of doing this was to make a double
exposure in the camera using a mask or matte for each to
block out the part of the image to be added with the other
exosure. Eventually, this was done in a printer but
initially it was done in the camera to avoid additional
generations. Movies also added forgrounds, backgrounds,
skys, etc., with a method known as "glass shots" where the
desired added image was painted on a large sheet of glass
using semi-tranparent paint, and photographed against the
scene it was to fill. If done right the depth of field woud
be enough to cover up the difference in distance. While
crude this method was used well into the 1940's and maybe
even later.
Of course, in the early days of photography all sort of
dramatic scenes were assembled out of parts of different
photos, I've drawn a blank on the name for this. In any
case, while often considered to be not very respectable this
sort of multiple photo has a long history. Digital image
editors, like Photoshop, just make it easier to do (and
maybe do badly).
BTW, when I started out I used to add skys frequently.
When there was a spactacular sky I went out and photographed
it and put the negatives away for just this purpose.
