  Don't use a smart phone camera for it a decent dedicated digital camera will correct for that optically in the lense, but you are right that is an issue for smart phone cameras due to the physical lense size.Sent from my BlackBerry - the most secure mobile deviceFrom: miles.on...@cirrus.comSent: October 12, 2017 5:52 PMTo: prmari...@gmail.com; jason.bron...@gmail.com; scientific-linux-users@fnal.govSubject: Re: [EXTERNAL] Re: scanner  On 10/12/2017 04:42 PM, Paul Robert

  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.Sent from my BlackBerry - the most secure mobile deviceFrom: positiv...@gmx.comSent: October 12, 2017 5:51 PMTo: prmari...@gmail.comCc: jason.bron...@gmail.com; scientific-linux-users@fnal.govSubject: Re: scanner  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.

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.

Look at HP All-in-One devices.  I've used several models with
"HP OfficeJet Pro" in the model name.  I only use the scan function
and it's working fine with Xsane, also the ADF (when available).

Loot at a list of supported devices:

http://hplipopensource.com/hplip-web/supported_devices/index.html

I'm using them with Fedora, SL / CentOS will have older versions
of the "hplip" software, so look at the required versions.
