-Not too close, not too far
-Test at what distance your phone takes photos with the writing still quite clear (usually between 50cm and 1 meter)
-Take one side of a bookcase edge in the photo, it helps to find the books in the photos later
-Be sure to take the photo from the middle of where you want to frame, you want all the books to be legible, so you need to center the photo well
-Clean the lens well before taking photos
-Don't zoom in or out; zoom lenses often have poorer quality than the camera's basic x1
-It doesn't matter if your photos overlap a little, Biblioscan will only show you each unique book once
-Trembling as little as possible to keep the photo as blur-free as possible, (tip: buy a 5β¬-bluetooth-trigger on the internet when you've made your first sales, it helps a lot to take photos discreetly and sharper)

β Good photo: clear, centered, showing book spines clearly

β No tilted photos that don't face the camera

β No photo too close where there are no horizontal ends of book slices
