But here's a suggestion:
You can have a look!
The first is shooting:
1. Choose a good weather (for novices with poor lighting): cloudy days are the best, outdoors, with sunshine (no one should let the sun shine directly on the work), so that the work can receive light as evenly as possible.
2. Choose a good white balance: "cloudy day" is better, and warm feeling is more suitable for calligraphy works.
If the work is too big, it needs to be shot in several paragraphs. Be careful not to see through the work when shooting-the lens should be perpendicular to the work as much as possible, and the height and distance of the lens should be kept as much as possible when shooting each paragraph (it will lead to deformation and have a certain impact on the later synthesis panorama).
4, try to use a tripod, manually adjust the aperture (use the best aperture), shutter, ISO, white balance, and try to make the same piece of work shot separately without uneven exposure.
