For these samples, we photographed them using front lighting and then to simulate interior cabinet lighting, the same piece was photographed with light coming from behind (backlit). Glass installed into cabinet doors will look like “Frontlit” with no lighting applied from behind.
So there’s no confusion: “Bronze – Frontlit” and “Bronze – Backlit” (for example) are not two different types of glass. It’s simply “Bronze”, with two different photographic lighting treatments.
