Normally, because of limitation of zoom lens and the flashlight, when the camera is set near the book, the picture becomes extremely blurry or bright, making it impossible to see the text on the picture. On the other hand, if the camera is a little bit far from the book, the text becomes so small that you can't read anything. Moreover, changing the focal length of the camera is of no use, and the picture only becomes blurry like shit. However, after hundreds of attempts and failures, I decided to put a magnifier in front of the camera, and it showed great result. Depends on the angle of the camera, the picture can be rather dark or bright, but the text and details of some areas become even clearer than what you can see with naked eyes. Here's a demonstration :
You see, in this case, the text is completely readable. The sharpness is even close to that of scans. For me, this will save a lot of effort when translating the manga and novels I order, since I won't have to open them so many times to read the text again just because I can't take picture of the text.
