No it would not produce parallax that the is the point of using a photo copy stand. That is how Profesional photographers have been copying photographs without the negatives since the beginning of photography it's a rig designed to prevent exactly that.

Now the down side is a good photo copy stand is expensive ($400+) but the one he is using actually originally belonged to his father. Really good ones are a one time high quality investment that will out last you, but you can get cheap ones (less than $50) that will last a decade or more of constant use too.

A single point of imaging would produce paralax -- if that matters.
Otherwise , an efficient 'hack' .
On the plus side , could 'scan' a non-flat object.

Interestingly my father threw me for a loop on this now a days a low grade digital camera actually has higher resolution than most scanners so he uses one in a photo copy stand and then just copies the one file to his computer via a bluetooth enabled SD card which is faster than any scanner on the market. Then he uses gimp or photos of depending on which computer he is using to crop it and convert the format if need.
He told me this actually works faster and easier than any scanner he has ever used and gets higher resolution as well and requires no drivers. All you need is a photo copy stand which is a rig you attach your camera to the holds it level to a surface.
Its a fascinating idea and I'm sure he is right about it, and it's probably the way I'm going to do it in the future.

I'm currently using an older Epson Perfection with a reasonable degree of success. HP is probably going to be your best bet for any kind of stable use and long term support, though. It'll function correctly on about anything until the unit dies from mechanical failure.

I've only had MFPs the last 10 years or so, with printer and scanner
integrated.  These are my general experiences on a few brands

- Canon
  Horrendous Linux support, network scanning basically impossible.  USB
  scanning may work reasonably okay.

- Brother
  Functional Linux drivers (also on RHEL), cumbersome setup but once
  done even network scanning works reasonably well.

- HP
  One of the best driver packages I've used.  Newest hardware can be
  tricky and may require building hplip package manually.  But the web
  page is quite good at listing which driver version is required.
  Network scanning works very well, even AFP with duplex scanning.  And
  for USB scanning, this works also very well.

  Downside: requires a binary plug-in to be installed post driver
  install.  This is basically a required closed source/proprietary
  firmware to enable scanning.  This can be installed both via the hplip
  command line and GUI tools.

I'd recommend a HP MFP device any time.  If you can find an older model
on sale, you'll get big bang for the bucks with a big chance it will
work out of the box once the hplip packages are installed.
