==Photos==
Any photo is better than no photo.
Prefer high-resolution, in-focus photos.
Don't use photos from other websites if you think it will upset the owner of the photo.
Prefer diffused lighting (no hard shadows), natural color balance, and good color rendition.
Good color rendition often comes from having minimal glare, which often comes from diffused lighting.
Prefer photos with low noise (without artificial denoising).
Low noise often comes from having adequate light.
Prefer photos without the in-camera flash.
In-camera flashes usually result in high glare, hard shadows, and poor color rendition.
When photographing an instrument, it's good to also get internal photos.
