Scan, or shoot?
The most simple way to capture a book is to scan it, if you have access to a scanner. Leave the scanner hood open for a black background or closed for white. But if it’s too big or you don’t have a scanner, you’ll need to use a camera.
Cameras (and lenses) vary wildly in terms of quality and ease-of-use, but really just use what you have access to. I would say using a phone camera is a last resort option. You can still get great images, but when shown large on a laptop or website the images just won’t be as crisp as you might like. See if you can borrow a friend’s camera, or even rent one online.
1. Identify what makes the book particularly meaningful to you
Is there a particular print process, binding, layout, material, or otherwise that you want to highlight? Is there a particular spread you want to show? Make a note of them.
2. Consider the context of how you want your book to be shown
Do you want the look of your photographs to be very stripped back and minimal? If so, consider showing it laid flat, on white, square-on to the camera, with even and flat lighting.
But that’s not your only option. You could consider showing your book more playfully, with props, on the floor, on a desk, or even a shelf. Do you want to shoot it on grass outside? Are there multiple copies of the book that you can arrange? You could also have a mix of two styles: some straight-on spreads alongside a few playful ones. The tone of voice is up to you.
