How to shoot calligraphy works with a camera

When shooting calligraphy works with a camera, it is best to hang the framed works, install the camera on a tripod, adjust the height of the lens to the approximate geometric center of the works, use the standard lens with the best distortion correction to make its center line perpendicular to the works as much as possible, and use F8~F 1 1 aperture with the best imaging effect to make the white performance of the backing paper of the works better, and at the same time, take into account the black ink, and then increase it.
