Re: Medium range cameras

The same with the Ixus range using a 1/2.3 CCD http://en.wikipedia.org/wiki/Canon_Digital_IXUS And the high end prosumer S90 uses an even smaller 1/1.7 CCD http://en.wikipedia.org/wiki/Canon_PowerShot_S#Super_Zoom_S.2FSX_series Hmm... 1/2.3 is smaller compated to 1/1.7 ;) Have you considered an aft...

Re: Minimum Camera for Book Scanning

is there anyone trying to build DIY cameras?. If you take most electronic, i am sure you could get a very good one (resollution) with no so much money and very light!!! Do you mean a hybrid of scanner and camera lens? For what custom purposes do you need one? It's a very tricky thing to make out of...

Re: Camera Focal Points and Camera Placement Theory

point-and-shoot cams allow to set custom ISO, shutter speed and aperture, but not the focus. I agree to what mranderso posted here just adding that you can raise ISO to have faster shutter at the same narrow aperture. Noise that is associated with high ISO may be neglected in book scanning. Besides,...

Re: Screencast on basic Scan Tailor usage - help wanted

The current English version of the user guide is not too good. It's highly desirable for the source material to be copyright-clean. I got tons of Marine reference books dated up to late XIX century that i can share. They are copyright-free for sure. The only issue it that none of them are in Englis...

Re: mranderso's build

Thanks! Any lighting calculations I should be aware of when it comes time to redesign that will save me a couple of iterations? I have an idea of how to calculate a 'perfect' reflector for the distance and platen size that i have but before to solve equatations i need to take some college-grade geom...

Re: mranderso's build

Looks cool!

Does your design ensure even brightness of the scanned page?

What is the distance between overhead bulbs and the book?

Re: Clarification on platen design

I actually don't remember the brand of the plexiglass i bought. Shop salesman told me it is widely used to make stands and holders of advertising materail. My platen is 4 mm thick. Holes are easy to make with an electric screwdriver and a sharp, metal-grade drill (avoid putting much pressure when dr...

Re: What's broken about eBooks? What would un-break them?

Would be happy to own a light foldable ebook with a swiss knife-like solid angle to hold it open with just one hand when reading

also a perfect ebook defenitely needs to support colour images and read basic Office file formats

and maybe....some internet browsing :D
