The Kodak Wratten 2 #47A Light Blue Gel Filter is a 100mm (4 x 4 inch) optical gel designed for black and white film photography and technical imaging where controlled blue transmission is required.

A light blue filter passes blue wavelengths while reducing red and green, which lightens blue subjects and darkens warm tones in monochrome images. Photographers use blue filtration to enhance skin texture, alter tonal separation, and simulate certain classic film looks. Wratten 2 gels are manufactured to tight optical standards, making them dependable for repeatable results.
