Scan A Book With A Digital Camera

Consider using a digital camera the next time you need to reproduce an entire book or a portion of one. Because digital cameras come in very small sizes, you can easily carry one with you for quick book scanning. There are a couple of considerations when copying text with a digital camera.








Instructions








1. Use a camera with 3 megapixels or higher. To reproduce clear, readable text, a greater megapixels number will capture the book in a higher resolution, allowing you to zoom in later and see the text clearly.


2. Hold the camera very still to prevent blurring. In addition, if your camera allows you to adjust the shutter speed, use a faster speed to reduce the risk of blurring. Alternately, use a tripod to hold your camera perfectly still.


3. Provide adequate lighting. You can use a faster shutter speed when the book is well illuminated. While you can use the flash on your digital camera, if you want to reproduce an entire book, it will drain your battery quickly. Try putting the book on a windowsill but avoid direct sunlight that may result in a glare.


4. Adjust your focal length if you're using a digital Single Lens Reflex (SLR) camera. Using a 100mm lens and zooming in reduces barrel distortion and increases readability. With a shorter lens, the three-dimensional properties of the book are out of perspective.


5. Flatten the page you are shooting. A rounded page will result in your camera focusing on only one area of text and the rest may be unreadable. Use another heavy book to brace the edge of the page flat. Alternately, use a music stand with an arm that holds the pages flat.
