From the release:
Hangar 18 Miniatures proudly presents new colors and textures for the tabletop photo backgrounds: High Definition Basic Textures Tabletop Photo Backdrops for Miniatures. We have been getting requests from miniature painters who paint professionally for miniature companies/manufacturers to produce a simpler texture with neutral colors. So we decided it's time for us to expand our product line to fulfill their wish.
This neutral and basic set comes with 6 different studio quality textures, using simple shades of grey and blue. From basic linear gradient, clouds to abstract mineral textures of concrete and slate. These photo backdrops will enhance the photos of your miniatures, making them look like they've been taken in a professional photo studio setting. No more spending time removing the plain background and replacing it with the digital background in Photoshop.
Hangar 18 Miniatures HiDef photo backdrops are printed on two different sizes: A3/Tabloid (11x17 in) and A2 (16.5 x 23.4 in) and using a durable yet flexible fabric that is water resistant and does not produce glare. If a backdrop gets dirty, you can simply wipe it with a damp cloth. This fabric can also be ironed or steamed to smooth it back when it gets wrinkled. Iron the backdrop face down on the ironing board.
