How to shoot calligraphy and painting works?

Now, digital cameras are used to take pictures. If you are still using old mechanical machines, you might as well buy a book on photography to learn. I can't say it here, really.

Besides, I do painting and calligraphy all day. When shooting paintings and calligraphy works, the most important thing to pay attention to is that you must invite them first, that is, let the mounting shop give them to you, so that the paper of the painting core will be "flat" and the invited painting core will be very flat, so that the photos taken will look good and will not go out of shape.

Take pictures with a digital camera. The main light is almost the same, and the focal length can be adjusted automatically. It can also be made by computer in the future.

I hope my answer is helpful to you.
