Should get an HDMI to USB-C thing so i can use the loved one's DSLR as a webcam.

what's a good one?

@davidgerard Anything with a MS2130 chipset - brand doesn't matter, they're all basically the same inside.
@dusk what are some examples? I'm looking for stuff to add to an Amazon wishlist.
@davidgerard Literally just search for "MS2130" - https://www.amazon.com/dp/B0CMT5SNFQ is one example but anything with the same chipset will be just as good.
