If it is an appearance patent, it is best to use CAD drawing, which can clearly export 6-sided views, which is better than shooting.

Extended information:
Patent laws vary from country to country. China and most countries require inventions to be novel, advanced and industrially practical. Novelty means that on the date of filing the patent application or the priority date, the invention is unprecedented in the prior art, that is, it is not publicly known. Any disclosure in writing, tape, record, photography, oral or use, etc., will lose its novelty.
Some countries use world novelty, some countries use domestic novelty, and some countries use the world scope as the standard for public knowledge, and the domestic scope as the standard for public disclosure. Advanced nature, also known as creativity, means that an invention is more advanced than the existing technology when applying for a patent, to an extent that is not obvious to ordinary professionals in the technical field to which it belongs. Practicality means that the invention can be manufactured and used in industry.
