Significantly darker and slightly more prone to wrinkling. Only works well when using low tolerance chroma key settings in a perfectly bright, evenly lit room; with higher tolerances (e.g. to avoid anti-aliasing problems) it is not ideal. If there is little ambient light in a corner or a crease from indirect light creates a shadowed area, it will stop working as a green screen background. It also sees through the fabric, but not much more than expected for the price. An extra star because it might be enough for some use cases, but it definitely doesn't meet the requirements.
