There are many different types of glass backgrounds. You can choose a white background or one with black reflections. A textured or blackened background will also work well. A patterned paper hanging from the ceiling can create a textured or patterned look on the surface. A black or dark gray background can be a great choice if you are using it for a black and white image. If you are using it for a coloured image, you should experiment with different lighting techniques to make the image stand out.
