It's rare that I see an Instagram ad that’s worthwhile, but I have been struggling with how to take photos of reflective things without a full-on studio setup. This translucent cone is a huge winner from V-Flat World: https://vflatworld.com/collections/the-light-cone-karl-taylor First photo is Peanuts comic in sleeve; second is viewing through cone; 3rd and 4th are photos through cone—single light source. The site recommends using inexpensive desk lamps on either side for evenness. (Not a paid endorsement!)
