Re: Portable Build Lighting Question

Oh, and just fyi, I am not using any JPGs in the production of the scanned books -- I am using TIFFs from the camera RAW (cr2) files, as they are lossless and uncompressed. So the camera settings themselves, I believe, won't have any effect on my images.

Re: Portable Build Lighting Question

Two JPGs attached. 0789 is a clean fresh white sheet of paper with the black base visible at the edges. IMG_0789.JPG 0788 is the same sheet of paper with optical zoom set to only display the white. IMG_0788.JPG Thanks for any advice and help on this. I can also provide CR2 RAW and TIFFs made from RA...

Re: Portable Build Lighting Question

Thanks for the quick reply and offer of help. I will nab shots of blank white pages when I get home tonight and post them, but in the meantime, my flickr portfolio has a JPG of a book page and a TIFF produced from the CR2 RAW: http://www.flickr.com/photos/84319956@N06/sets/72157630916182714/ I'll po...

Re: Portable Build Lighting Question

I am finding that the 10w LED flood is not generating enough light for my cameras. This may be in part due to less than perfect cameras, but my images have a good deal of color noise due to insufficient lighting. I am going to start looking at swapping out the 10w LED for something in the 20-30w ran...

Re: Dr. Cheap's beta kit build

Thanks. I have put up some images on a Flickr feed. The JPG (which I am not using), a TIFF (made from a camera RAW CR2 file), and the TIFF post-Scan Tailor. http://www.flickr.com/photos/84319956@N06/sets/72157630916182714/ I showed these to a friend who does design and photo work and he recommended ...

Re: Dr. Cheap's beta kit build

I could use some advice on getting better quality images for OCR. The OCR results from Acrobat 7 have been pretty poor. I have been shooting without zooming in to frame the pages, so my resolution on the original images are only about 300 dpi. Combine that with the poor OCR of Acrobat 7 and the OCR ...

Re: Dr. Cheap's beta kit build

Scanner is up and running. I need to do some cable management work and also tinker with the scantailor and acrobat settings, but here is a sample pdf from a 1901 volume I was using for testing today.

Re: Museum glass: before and after shots

Just fyi, I found Tru-Vue Museum Glass at the local Hobby Lobby. Walk in, asked for 11x14, they cut and wrapped it in a few minutes, $30 per pane. $60 for two panes of glass is still pricey but it's a darn convenient and a good price for museum glass as well. Michaels sells "masterpiece" glass but m...

Re: Planing edges on baltic birch?

After playing around with this during my build, I would recommend simply using a small hand-held power sander (I used a SKIL "Octo" sander) to round the edges. Planing the edges is not worth it. Two problems with planing: 1. Most significant it that the pieces have a great deal of interior corners, ...

Re: Dr. Cheap's beta kit build

Minor progress today. I made some amendments to the basic plans for comfort and looks. First, I replaced the handle assembly used in the plans with a 3/4" wood dowel and a bicycle grip. I attached that with a 2.5" screw, a washer between the dowel and the bearing. Pre-drilling the dowel required a l...
