A place to politely discuss the tools, technique and culture of photography.
This is not a good place to simply share cool photos/videos or promote your own work and projects, but rather a place to discuss photography as an art and post things that would be of interest to other photographers.
Not sure about how to use this as a gift, but I can tell you the way to photograph artwork, it's called "copy stand lighting" this discussion thread shows some setups https://www.photrio.com/forum/threads/copy-stand-lighting.181663/
Could be as simple as a couple of gooseneck lamps.
You want a polarizing filter that fits the lens she uses. You twist it and adapt it to glare so it disappears.
For small items, you can get them a small lightbox on ebay for under $25. For the larger items, a couple of ideas.
You need better lighting setups. Two things you could do. Buy some speedlights. There's generic ones for around $40 that work just fine. Need to make sure they have the slave/master relationship. Get some help buying the right gear.
The other thing you could do, buy one speedlight, and get a bounce source with a way to keep it upright.
