Re: [Scanner-Build] Ram-Book (1 cam, 2 pages, 3rd cheap)

However: there may be a way to correct the original image in LR3 (and most likely Photoshop) without requiring dual runs into ST.

Let me look into this...

Re: [Scanner-Build] Ram-Book (1 cam, 2 pages, 3rd cheap)

hmmm. well, I'm not sure what will get you the initial splits + them exported as fast as possible. But you'd want to maintain your output quality because once you keytone-correct, they'd be going right back into Scan Tailor. Tulon might know if you output the initial split to B/W and re-import if is...

With Lightroom 3 you can even save your keystone-correction as a preset edit. If your shooting angles remain the same, the right software to make your life painless is LR3.

Re: [Scanner-Build] Ram-Book (1 cam, 2 pages, 3rd cheap)

and I've noticed that vectorizing keystone-corrected text images is beneficial; it will really clean up text when shooting books like this. Apps like Potrace, Inkscape, Vector Magic and Adobe Acrobat's ClearScan feature in OCR can vectorize post Scan Tailor images.

Re: [Scanner-Build] Ram-Book (1 cam, 2 pages, 3rd cheap)

Lightroom 3 automates keystone correcting as well among so many other fantastic batch processing features which help prepare images for ScanTailor. One interesting thing here is you need to batch split before keystone-correcting each image (which means sending every image into ST-->auto split-->outp...

Re: A scanner for fileslips and field notebooks: It's a Box!

Yes sir, this this approach with no fasteners on the frame is nice. Interlocking rabbited-style joint system (or whatever it's called). Like a true carpenter....with a lazzzer.

CHDK script to auto power-on cameras?

FIle this under 'luxury features': Is there a CHDK script that can power-on cameras when they receive current from their respective AC brick? I'm not saying I'm too lazy to turn on my cameras, but when the power strip is flipped on, wouldn't it be cool if everything started up? Probably impossible. ...
