Re: Scanner in a Briefcase

Can go at 900-1500 pages per min (see video) which is almost as fast as many 2 camera scanners and faster than some. Speed depends on skill, type of trigger and size of book.
LOL. You're off by a factor of 60.

Re: Would it be possible a video scanner?

This idea has been discussed here over the years. You can search through the forums for 'video' and probably find a half-dozen posts about it. The important point is to ask yourself how much time are you going to save by developing and using this method over the typical dual-camera V-cradle DIY scan...

Re: glass platen construction

Get a glass door pivot hinge and mount it on the side edge (rather than the back edge like in the photo). Glass Door Pivot Hinge Those brackets look similar to a shelf bracket, but most shelf brackets don't have a long slot for the screws into the wooden shelf. They are probably custom made for this...

CR2V seems to have been replaced by a Windows application called "VectorEye" in 2003.

Re: Removing chromatic aberration

Is your post spam?

The link you posted has nothing to do with chromatic aberration, Photoshop, or Lightroom. Did you make a mistake?

Re: Clean your camera lens

If your lens supports threaded filters, adding a UV filter is an inexpensive way (<$10) to protect your camera lens.

Re: a small story for my scanner

You're correct. We don't know how much brighter the light is at the lower edge than the upper corners, only that it is brighter. What I wanted to make apparent is that in that image the light is brighter near the bottom of the page and that distinctive circular pattern across the various levels indi...

In the image of both of the book's pages, the light looks as if it were pointed at the lower half of the page: 2PpmMjC_2.j...

Re: Using SORAA Snap System Beam Spreader - Uneven Lighting

Something to try.... Put a piece of white paper over one side of the platen glass (place OVER the glass, not underneath). Put a black piece of paper (or better, a piece of black velvet fabric) over the other side of the platen glass. Photograph the white paper. Next, replace the black paper with ano...
