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 ...

1) In principle 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 ...

I consider there are some rules for chroma keying. 1. A color that is the opposite of what is in front of it. 2. A bright color, mainly a primary RGB color. This way one channel will have enough contrast to be used as a mask. This limits the options to R, G, B but you could use bright orange for example and change the hue to extract a mask. This color ...

The only way to know is to test your lights to see if they work well together. Lights that are rated the same temperature may not be. Lights that are the same temperature may differ along the green-magenta axis. Lights that are the same temperature may have different Color Rendering Indices.

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 ...

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

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 ...

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 ...

Absolutely! You're using this for a video setup, but it's common in still photography with strobes, where this technique is known as "bounce flash". The caveat is that strobes — like from studio lighting, from hotshoe flashes, or even from the popup flash of a camera — are very short intense bursts of light. Your lamp, and probably even your spotlight, won'...

It will work after a fashion, but you'll get substantial reduction in light level when the light is reflected. In your application it may well be adequate. If you wish to use a diffuser you do not need a formal or commercial one. The paper that you intend stick on the wall could be used instead as a diffuser - it may prove too opaque, but it's easily tried....

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 ...

It's entirely possible there is enough difference in the plants and the background to pull the subject off the image to drop onto another one relatively well. It might involve how the subject is lit for the shot instead of the specific colour. "Green" screen is a generic term now. The original screens for traveling mattes were more blue. The characteristic ...

You can use use many product for remove green screen. Photoshop, Gimp, PhotoKey. But to get acceptable results you should follow few rules Make the background flat, w.o. any shadows and so on Use it with the foreground objects which do not have naturally green Do not light (artificial or natural) the green screen or make the light on it as flat as possible ...

As there is no way to synchronize the frame capture times between the two DSLRs, you cannot record in 3D. You would need to make some kind of a synchronization circuit and for that you need to hack into the DSLRs - way too complex for your project I guess. You can create 3D images though this way as single-triggering two cameras using one wire or wireless ...

Your setup should be sufficient with the white paper on the wall and a neutral white (not warm, not cool) lamp. However, if you are going to chroma key out the back drop, your setup may cast your shadow onto it. Having a uniform backdrop is essential when using chroma key. You can do a couple things to reduce or eliminate shadows on a backdrop. Add ...

You, sir, are right on. What I like about your propposed setup is the simplicity, and the effectivity. You'd save space, time and money and will be able to get very, very good results. You can improve the reflactivity of your bounce difuser by choosing solid cardboard as white as possible. You can also use translucent paper with aluminum foil as a backing, ...

Another possibility is to take advantage of the "select in focus" geature now in Photoshop! I've not tried it yet but I think a fuzzy blob patches of color will look like it's way out of focus even though its still in your depth of field. As for masking, if fringes would be a problem, or tinted reflected light from the background is a problem even when ...

Any constant shade background that is high contrast (and doesn't use the same color) as your object will work for trying to do an automatic removal. The best quality is often still accomplished by manually extracting the object with matte or selection painting in post.

So, I'm doing the same thing. I work for an off-road manufacturer; we make skid plates, roll cages, roll cage add-ons, etc., and I take and edit the images for the site and media. I envy your greenscreen room, as I have to get creative and hang 2x20x30 green screens as needed. Anyways, on to the point here: I run into this same issue. Green works for me ...
