Re: Which one is better? Platen's angle 100 or 90 degree?

i imagine in 90 degrees you need more effort to flatten the page than 100 degrees ,or the page will get fold .(but thit is gonna tell you if happen people who have 90 degrees scanner ) : I think 90 degree is more better to flatten the page. If you make pages even it is hard because of the book's gu...

Re: Which one is better? Platen's angle 100 or 90 degree?

Oh. I got it. Now I understood Daniel's second video on YouTube. And I tested it on my smart phone(black screen) with wallet case. Thank you guys, konos 93a, dpc, cday. Dpc's comment was decisive to understand it. Thank you so much. My last question, how can I show the image on this Web site when I ...

The problem with using 90 degrees is that the camera will "see" the reflected image of the adjacent plane.
Do you mean the reflected image of the adjacent plane still show each other even at the 90 degree?

Re: Which one is better? Platen's angle 100or 90 degree?

There's a trade-off worth mentioning here as you increase the platen angle between the two panes it makes the platen panes more conducive to picking up a reflection of the overhead light source. The mitigation for that is to move the light source farther away from the platen. -----------------------...

So i want to know why Daniel used a platen of 100 degree angle.is it better than 90 degree? Because of More brig...

Re: My 2nd new book scanner!

What is "tubing"? You mean "steel round bar" or left side handle? If I install the camera on the platen, the camera can be shaken even though it is tightened. This means you could get a blured page. As you know, the more faster, the more shaking! I wanted to reduce the vibration ...

Re: My 2nd new book scanner!

The enthusiasm for your book scanner makes you realize more. I hope you have more confidence in your scanner. When I scanned a book with a Canon sx200 I used zooming for a small book. In this case I experienced two problems. First, I had to move the camera to be centralized. So I need a 4-way(up &am...

Re: My 2nd new book scanner!

This is my first scanner that I made without platen. I could adjust the length to press top and boottom of the book.

Re: My 2nd new book scanner!

First above all, I am sorry for my comment, "one big problem" on your scanner. It is not "one big problem" as you mentioned. I apologize for the roughness of my expression on that matter. At first I wanted to make a book scanner without a platen. But the pages were not even than ...
