Most of us don’t have a studio, high-end lighting or cameras. In a studio with first-class lighting and high-end cameras. Better suited for removing colors from graphics with defined lines and borders. That’s pretty much the extent of its capabilities. While it is capable of doing a decent job. So that you’re not casting shadows upon yourself. You want light falling on you evenly from all directions. You want to use soft, diffused lighting if possible. ![]() Ideally, you should be a minimum of four feet from the screen. You’re probably limited as to how far you can position yourself away from the green screen, based upon screen size and room conditions. This is especially problematic if you’re positioned to close to the green screen. The reason there’s green fringing surrounding you? The backdrop itself may be casting green back upon you. So there’s very little for the filter to detect/ key out to your detriment. In general, most colors don’t contain a lot of green. The filter is incapable of differentiating what absence of color you wish to save, and that that you don’t. There’s only so much these adjustments can do. The Tolerance, Softness, Hue and Defringe adjustments help clean up/tone down the spillover/removal. The filter will detect this absence of color. Is absent of a certain degree/percentage of color. Why? In a nutshell.įlesh tones, your eyeballs, most colors, particularly light colors, including room lighting bouncing off you. ![]() Using a White Backdrop as if it were a green screen. the green will contrast MUCH more with other natural body tones, and you'll be able to pull out the color much better.īackdrop lighting is always fun once you get it, but frustrating until you do! :) Even if you don't go to the trouble of ironing it out, lighting it better, etc. Go with a green backdrop, and replace that in post. This is the approach I generally take when I want a white backdrop, and I usually have to break out the portable steamer, a few extra backdrop lights, move away from the wall, etc.Ģ. I definitely think that you'll get your best result (trying to get a pure white background) by doing one of two things:ġ. Another potential issue is that there is some white background leaking through your hair (or in the case of your eyes, picking up the white color from your sclera), and that is just bleeding out onto the black areas around that as you play around with the tolerance, softness, etc. I was chatting around with some of our devs, without looking at it, it's certainly possible that it could be an issue with the color removal (odd that it is removing black when you're choosing white). I grabbed your source screenshot that you posted and tried playing around with some of the settings on the color removal, but didn't have much better luck than you. (And of course as-displayed "pure computer white" isn't white either, but as long as I can match it, there won't be a contrast to the web page background.)Īaaanyway, thanks! You have given me some good ideas! But regardless of the backdrop I will probably need to color remove whatever white I use as a backdrop since it won't quite match a computer screen's idea of pure white. ![]() Your point is well-taken though, and next time I'll steam out the backdrop and throw even more lighting at it. It may be weird, but I figured I could fix the not-quite-white by using the color remove on a computer white background. I want it focusing (pun intended) on the 60 fps since I think that makes a nice looking video. ![]() It is only a webcam after all, and all that information needs to go through it to the SSD. I have the camera using 5500K as its white balance. I am using 5500K light sources and there is a camera involved. The problem with "white" is that there isn't really a white. It is a white muslin backdrop that came with my lighting and backdrop set. Is this a bug? I'd like to just remove whit-ish and let the pure white show through in one step. They do make the grey in my hair and beard quite brilliant though. I found a workaround where I layer the same video, the bottom layer colorized with white at 23% then a top layer where I removed that same off-white color as above. It seems like the color removal is "wrapping around" and taking out black as well as white, which is unexpected. To my surprise, while it removed white, it also removed my dark hair and beard, shadows, nostrils, etc.Īnd here is what happens when set the canvas to white, and I remove color and use the eyedropper on the upper right off-white background, default settings:Īs I don't want to terrify my clients, this won't work. I was using it for making a white background anyway, so I dropped a white background, thinking that I could remove color with the eyedropper to get a pure white background to blend into my website. The remove color works well with a green screen, but given that I am using a webcam the compression blends the edges into a color between green and the edge which left a green halo.
