General Specialist - Tips, Tricks and Tinkerings green screenShooting for greenscreen or bluescreen? Here's a list of hard-earned experiences from the shoots where I've been vfx supervisor. I don't claim to be a chroma expert, so please post a comment if you have more tips to add to the list! Keep It Blurry Turn off all in-camera sharpening! This might make your director of photography (DOP) nervous and it will certainly make it harder for her/him to focus. On Sony cameras, there's usually two settings that need to be turned off: Detail and Skin Detail. By default, all cameras apply a sharpening filter as a post-process before each frame is committed to tape/disk/memory card. While this makes the image look better, it is makes it so much more difficult to get a good and clean edge between your foreground and your chroma screen. Digital sharpening works by finding adjacent pixels of different lightness values and then increasing the difference, in effect crating a border with much higher contrast. Notice also how the in-camera sharpening brings out noise and imperfections in the chroma screen. So shoot without sharpening and add it in post instead! click here for the complete article. Very indepth, excellent advice.
