Question

If I printed tons of papers, with the color of a green screen, Would it work?

Answer 1

gobonzzo is right, but rather than using sheets of wood, use expanded polystyrene - it's much cheaper, lighter and easier to handle.

Answer 2

yes but make sure you make the printer print it by mixing its colors

Answer 3

no i think the inconsistantcy would be the biggest problem. not only has the screen have to be exactly the same colour all the way around but the lighting must also be equal.

editing the shot relies on the best possible colour/lighting to enable a smooth key.

find a fabric store and make sure it's thick enough for no light to pass thru.

you can buy some for as little as $10/meter.

also, when shooting for green screen make sure the cam is around 5 to 10 meters away form the screen and adjust depth of field to allow slightly blurred background.

hope it helps!

Answer 4

Go to a fabric store.

Answer 5

it would run your printer out of green ink and it would be very expensive, but yes it would work.

Answer 6

As long as you had enough paper and ink

Answer 7

Maybe you could find a paper that is already green?  That would be a lot cheaper and less hard on your printer.  Or you could go to a teacher store and get some green bulletin board paper - they have every color you can imagine for that.

But I don't know anything about "green screens" - good luck!

Answer 8

Save a tree please...

Answer 9

If you're thinking about making a green screen for photo or movie effects, there's no reason that a background made from printing page after page of green shouldn't work.

However don't take green screen too literally.

The particular shade of green that is used professionally is used because it doesn't generally occur in nature.

Adding a background requires that you make transparent the green and it's easiest to select all pixels of a given color if that color doesn't appear anywhere else in the image.

If your looking to green screen a single picture rather than a film ANY color will do that is sufficiently different from what you're photographing.

Blacks and whites are bad because any colors that are over or underexposed tend to read as one or the other.

A light blue sheet (no pattern) hung behind your object would probably work as well and be cheaper and easier.  Other colors might work as well depending on what you're photographing.

Answer 10

Well.... ummm.... Short answer: ... first, your camera must have a 'chroma-key' function.

long answer:

'Chroma', meaning color... and 'key' (in the video world) means to place over. Basically, Most consumer-grade cams, if they have this function, are limited at best. Pro-grade equipment allows you to choose the RGB color(s) which you want to 'key' over. like the news & weather casters often have a (usually green)(sometimes blue) screen behind them. Reason 'green' is used most.... that bright green is very rarely found in the die-colors of most clothing, and business attire (which pro anchors wear)... therefore, it's much less likely that there will be a 'chroma-key' conflict.

Most people, esp. older.... may remember in the 70's & 80's... a weather dude standing in front of his weather map... and his tie or parts of his jacket kinda fizzled, and you could see parts of the graphics behind him, within that fizzling area. What is happening there is... the first couple of generations of chroma-key units weren't able to get all that precise... so, they'd pick up anything within a certain range of the set colors.

The way it works... there's a graphic, or video, or still shot.... whatever... which is the desired background... usually, a weather map/graphics. The 'talent' (the anchor) stands in front of the 'green screen'. That camera which is shooting the person, captures him/her in full color... and the background, which is painted that particular shade of bright green. The chroma-key looks at the feed from that camera, and says... 'ah! everything that is the preset color (green), will be replaced by whatever the desired graphic is'.Therefore, what you see is a composite in layers... the anchor in the front, and the graphic is behind the anchor.

So back to your question. Check your manual to see if your camera has a 'key' function. one of mine... a Panisonic, has 'lumikey'... which basically is the brightness. it sees and separates the brighter areas from the darker areas, and 'keys' using brightness, rather than color. If your cam is the same, then the background color won't make alot of difference... just black or white. If your cam DOES have a true chroma-key mode... read the manual and understand it, first. Then, try doing a test. if you print-out a colored sheet... just try one. That uses a great deal of ink... and printer ink is expensive. it may be a great deal cheaper to buy paint the color you need, and make a background substrate you can paint.

Or- if you can adjust the chroma-key color that the camera is looking for, you may beable to use several sheets of colored poster board, and staple it to the wall, as the background. Chroma-key's usually won't pick up such detail as the seems between the posterboard... or the staples... stuff like that.

Don't put a lot of money into this... being 'consumer-grade equipment... even if your cam will do it... it probably won't have the user-controls to make it adjustible enough to come-off all that well. If you're really serious about this, google 'chroma-key' equipment. most of what you find will be pro-grade gear. You may find some 'industrial-grade', which is between the high-end consumer, and low-end pro.
