Re: Minimum Camera for Book Scanning

Dan, At the beginning of this thread you said this in a post: "I still think the Powershot A590 IS is the best camera for the job in terms of price and performance." My questions are: . . . 2)I didn't see the A590 in the list of cameras supporting SDM, do you know if it supports it? This may not be...

PTP (and Pictbridge)

Picture Transfer Protocol The is a camera capability of interest to people on this forum for its potential to enable remote firing of cameras and remote viewing (on a PC) of recently taken shots. Posts on forums that discuss PTP sometimes note that different cameras implement PTP differently, so a c...

Re: Problem with "Select Content"

Could you give some advice on using a regular scanner rather than a camera? I am having a lot of pages where Scan Tailor incorrectly determines the text area. I am no expert, but I have been scanning books on my Plustek Opticbook 3600 for years and recently had a very good experience splitting the ...

Re: Daniel's 5th Generation DIY Book Scanner

Thanks, folks, for the helpful input about high-capacity (but regular write-speed) SD cards I'd like to repeat my suggestion that tests be conducted on card write speed unless it is trivial to get replacement high-speed cards in Haiti if needed. It makes sense that this would seem to be a non-issue...

embedding hyperlinks in text in these forum posts

To whom it may concern, I've have been posting comments with links but knew only how to cut and paste a URL into a comment like so: http://www.google.com But embedding links, especially long ones, into words looks much nicer . The forum FAQ says there's a guide to the phpBBB software that powers the...

Re: Flash vs Continuous Light

I wonder if anyone is using a flash instead of continuous light to save electricity? Is it possible to get the same or better results using flash? What are the advantages/disadvantages? In the summer Daniel Reetz worked up an LED-based flash lighting system here: http://www.diybookscanner.org/forum...

Re: Daniel's 5th Generation DIY Book Scanner

Does anyone know the maximum capacity SD card that the Olympus E-P1 can handle? I have not found that info in the manual. Apparently at least up to 32 GB. A DP Review forum member asked about the use of large cards in Olympus EP-1: http://forums.dpreview.com/forums/read.asp?forum=1022&message=32291...

Re: Glossary: DIY Book Scanners and Scanning

dear ceeann1, your glossary thread is a great idea, but i am thinking that thread structures are not well suited to the purpose past a relatively small number of entries -- the terms do not appear in the headers, and this site appears to be searchable only within individual forums (such as "hardware...

Re: web based access to one of Google's OCR engines

Rob, don't you use Adobe Acrobat for your OCR tasks (think I remember that from another post)??? If so, how does it work for you? I've got an opportunity to buy Acrobat Professional 9 for Mac at a discounted price. What does it do for file size before and after OCR? I've used Acrobat OCR exclusivel...

Re: Simple "looking" one camera book scanner

I will definately binarize my scans as the final size does matter for me - I want to put the books onto my iPad. The thing that always amazes me is how little difference the size of the source images seems to make to Acrobat. The most recent book that I scanned yielded 134 greyscale images at 8.7Mb...
