There's probably several different ways to skin this cat (there always are in Photoshop), and it's be easier to give specific input if there was a picture to look at, but in general I'd probably tackle the problem with something like this: Create a Hue/Saturation Adjustment layer Modify the layer mask such that only the area with bleed problems is selected ...


The green is there and is being reflected by the car. Eliminating it requires post-production which is exactly how its done with for visual effects in movies. You use a tool called 'Color-Curves' (or similar name depending on the S/W) and basically reduce the amount of green in green areas until it looks natural. A change in WB is not what you are looking ...


Why don't you take one shot with the green screen and another (from exactly the same position) with a white screen covering the green screen? The green screen will identify pixels to be replaced by scenery in the white screen picture. The white screen doesn't have to be perfectly white or even uniform; its role is to supply the desired lighting for the car ...


I'm no expert on this, but my basic understanding is that you generally want two lights, on either side of the background (not at 90 degrees to it), aimed towards the center, far enough back to illuminate evenly, and angled downwards to reduce spill. Continuous lighting is probably better for this, or at least makes it easier to ensure that you're correctly ...


1) In principal any colour will work, it is of course helpful to chose a colour that is rare in your subject, so red and yellow are out as they collide with skintones. Green has a specific advantage when it comes to digital photography as most digital cameras have twice as many green photosites as red or blue. 2) Black is less useful as black is not a ...


In addition to Itai's post production setting, two things come to mind for in the studio that are commonly used for video green screen: distance. 8 to 10 feet of it between the green screen and the object. MINIMUM. a linear polarizer, rotate it around to find the best angle to kill the bounce.


I also am a make up artist and I say put a little face powder on his head to remove that shine.


John Cavan's answer is definitely more thorough, but I'll answer from a tiny bit of experience. I took my kids recently to a Discovery Science museum here in Souther California, and they had a cheap green screen setup with a video camera aimed at it. The point was to let the kids try on different costumes and dance in front of the camera and see themselves ...


Lighting the background for the same exposure as the foreground is the most important factor. If you have green screen and you under expose the background, you will see the spill very clearly, and its tough to post process!


Here are all the ways I know of for removing the background (in order of my preference): White Background This is done by using a white-ish background and lighting the background about 3 stops brighter than the subjects (exact lighting depending on your camera). There's no way you can do this with household lights but a flash aimed at the wall behind the ...


Light creates shadows but also removes them. The key is simply to illuminate the object from below or lift the object above the background. For the color, green and blue are often used in video but then most people have to apply the spill-removal tool after the keying tool to cancel the green cast that appears on subjects shot next to a green screen. In ...


You do not need to photograph on a green background to be able to separate them out later. Green screens are used in video so that the process can be automated since many, many images need to be altered (24 to 30 per second of video). For still images, it is much higher quality to do manual masking to extract the objects since you only need to do it for ...


Any color can be used, the reason for green is that it is a color that isn't found much in most subjects and tends to give a bit less reflection than the old blue screen (which could lead to blue highlights on the subject.) You can still get that with green screen, but it's less common. As for black, that's a special case, when using a black backdrop it is ...


When you extract the banana from your original background, you'll tend to include some background pixels. If the background is white you'll have white pixels. If you then place that on a light background, those white pixels won't show much, but against a darker background, they will stand out. So as you're shooting the banana, if you can try to use a ...


I have only done this twice - so I am no expert either. But both times I have done it, the lighting on the background itself did not really matter - since they will be replaced anyway. John Cavan's answer is excellent in getting equal lighting on your background - but what I am trying to say is that that effort in doing that might be unnecessary for green ...
