Re: How to choose which build?

Before you decide which design to follow it is good to list the key requirements, just for yourself. This will save time and money for 'upgrades' once you realize that the scanner you now own is not exactly what you need. E.g. I was hurrying with my first scanner and made it not portable: had to reb...

Re: Book (camera-based) Scanner versus Flatbed Scanner

I have spent a fair amount of time hacking the guts of flatbed scanners. I have removed the edges of a CIS scanner (a canon LiDE series) and had the same issue. I have also tried to modify the optics of flatbed scanners to get right to the gutter. In the end, it was a hopeless waste of time. I stil...

Re: $scanning

There's a plenty of consumer grade flatbed scanners priced US$50 and up that can help you scanning up to a4/legal format. There are numerous DIY builds that capture up to A3-sized dox. But wide format scanners start at some $5K, not being in fact that complicated sort of devices for mass production....

Re: Book (camera-based) Scanner versus Flatbed Scanner

i am scanning mostly historic books. Even those which pages are falling apart because of completely dead binding still cannot be loaded into scanner's ADF as these pages are thin and will not survive an occasional jamming. modern books that i happened to scan were just not mine, so removing binding ...

Re: Memory card error

Had that kind of trouble with xD card (these are used in Olympuses and Fujies). They got a limited number of RW cycles, and i just run out of these once... anyway card write error is a resolvable thing. It's more sad to see that two-three pages of a 150-page book that is already given away are out o...

Re: Dropping out.

Hi Dan, Its your life and responsibility for making choices, but i would support your decision to abandon your studies. First, wrong education traps you within the wrong job afterwards. One who dislikes his job will never reach the hights. If psychology is not yours, the sooner you switch - the bett...

Re: "Archival Quality" Camera

My scanner works with EOS400d that produces excellent JPEG pictures out of 300x200mm XIX century paper originals. A3 format (400x300mm) may be captured too with satisfactory resolution. Larger sizes require more mpixels, better optics and light. If you don't need wide format and got a limited budget...

mine doesn't have a screw. Just some kind of 'stopper' fixing the moving barrel only in the most-compact-lens-size position (for safe carrying).

Re: Zoom lens vs prime lens - what's the disadvantage to zoom?

in my design i use canon 400d+tamron 17-50/2.8 and my experience (of some 40 books) pushes me to find a bright prime lens with manual focus (MF) when a DSLR camera with zoom lens is looking upwards or downwards, the gravity pulls the 'front tube' outside or inside the rear tube (sorry i don't know t...
