The DigiComp® HD color standards are precisely manufactured for crisp, clean separation of the foreground/background in digital compositing – resulting in little or no post-production "touch-up" needed. Rosco DigiComp® HD paints are specially formulated to provide the proper luminance and RGB values for optimum operation of all digital compositing systems.
Precision in Color
The DigiComp HD color standards are precisely manufactured for crisp, clean separation of the foreground/background in digital compositing – resulting in little or no post-production "touch-up" needed. Rosco DigiComp HD paints are specially formulated to provide the proper luminance and RGB values for optimum operation of all digital compositing systems. The precise formulation of the single-source pigments found in DigiComp HD paints produces a highly-specific spectral reflectance and high-gain reflectivity, which results in a bright, narrow bandwidth of green or blue that make it both simple to light and easy to key.
DigiComp HD saves productions valuable post-production time because Visual Effects technicians spend less time rotoscoping and manipulating a dirty key caused by the spectral interference found in other generic or paint-store mixed formulations.
Rosco’s DigiComp HD formulations are ready for use straight out of the can and provide even coverage in two, easy-to-apply coats. DigiComp HD is intended for use on most porous surfaces, including: wood, wallboard, sheetrock, plaster and concrete. It is always recommended to properly clean, prime and prepare your surface before applying the DigiComp HD paints. Unprimed surfaces may result in uneven color-coverage. DigiComp HD paints can be applied using 3/8” nap roller or a spray gun. For full application instructions, please see our How To Paint Your Wall/Cyc with DigiComp HD document, or watch the video.
All of Rosco’s keying paints, including DigiComp HD, are manufactured to have an ultra-flat finish, which means there is no sheen or gloss in the finish at all. It’s worth noting that the “flat” finishes available from paint or hardware stores will have some sheen to them when lit for camera – Rosco keying paints will not. This is important because any sheen/gloss in a green screen will appear as white or yellow on camera – not green – and may spoil your key.

Choosing the Proper Color
DigiComp HD is available in both Green and Blue. Most experts say that if you’re shooting on film – use blue screen because the blue layer of the film emulsion is more sensitive. If you’re shooting digital/HD – use green screen because the chips in most digital/HD cameras are more sensitive to green. However, the subject matter you’re shooting also needs to be considered. Avoid matching the background with the major elements in the foreground. For example, a green screen would be a better choice if the selected set pieces or costumes (such as a blue super-hero suit) contained a lot of blue in them - no matter what medium you’re shooting on.
