Walimex pro Background cardboard 2,72x10m green chroma

Professional Background for Studio Applications
The background paper from Walimex pro features a non-reflective surface, making it perfectly suitable for professional use in the photo studio. With a paper weight of 160 g/m², the background is durable and ideal for daily use. Each background paper is wrapped around a sturdy cardboard core, ensuring that the studio background remains smooth without creasing or sagging. For transport, the ends are protected with a transport safety feature.

Chroma Keying or Color Keying
Due to its base color, the background is also ideal for chroma keying, also known as bluescreen or greenscreen, depending on the color. This technique uses a generally uncommon color for people, furniture, and clothing as a background to assign an alpha channel to the recorded image. The alpha channel defines the transparency of each pixel. In short, the background can be automatically recognized by the computer in post-production based on its color. The corresponding pixels can then be assigned full transparency, allowing the background to be removed from the image. The freed areas can then be replaced with any other background. When using the background for chroma keying, it is important to ensure that the subject does not contain the same or a similar color as the background, and that the background is evenly lit as much as possible.

Background on Hand for Long-Term Use
After use, the background can be rolled back onto the sturdy core. If the background becomes unusable after prolonged use, the corresponding piece can simply be cut off, and fresh paper can be rolled out. It is recommended to weigh down the end of the background paper lying on the ground to protect it from tearing. This is ideally done with the Walimex pro magnetic weight.
