very happy with my purchase
Color: Brown-F, Color: Brown-F
The quality and craftsmanship of this tray are amazing! I bought it mainly for jewelry photography, and the results turned out even better than I expected ✨
The matte finish is exactly what I needed because it doesn’t reflect light, which makes photographing jewelry and pearls so much easier and gives the photos a much more elevated look 📸
I took these photos at night under white lighting, and I’m honestly so happy with how they turned out. The background looks clean, soft, and aesthetic. Sharing some of my photos here for reference — highly recommend!
