The Reflecmedia Chromatte Small Blue Light Ring kit is an excellent way to produce seamless chroma key photographs. The fundamental question for chroma keying (using a monochrome coloured backdrop behind your subject then digitally replacing it with a different image) is: blue or green?Blue is typically the choice for television weather maps but green is often used for digital media as digital cameras retain more detail in the green channel and green requires less light than blue.This kit combines a lightweight, flexible backdrop containing millions of glass beads that reflect light like cats' eyes; and a camera-mounted LED light ring which, when used together, produce a bright but more importantly uniform blue backdrop for easy chroma keying without seams, creases or folds. The kit includes various adapter rings to meet your shooting requirements.Product Highlights:- Accurate chroma keying- Studio or field use- Easy to use- Flexible and adaptable
