Are you sick and uninterested in shooting (plus viewing) the same old photos, time and time again? You've heard that "blue screen" is the way to go, however you don't truly understand it or even know a lot about it? This is all you'll want to be familiar with to put it to use as a photography background!
Firstly…What is it?
You'll hear the expressions "green screen", "blue screen", and "chroma key" thrown about and used to mean the same thing when discussing a photography background.
Chroma key only means having a background that's one solid, uniformly illuminated color. The blue and green tend to be the most frequently used colors. In reality, you are able to employ ANY color - but blue and green tend to be best. I am going to make clear why that is the case in a second.
Chroma key techniques can be used for either video and still work. You shoot somebody in front of the green screen then we later (or at once working with high quality video cameras) you do away with the solid color and trade it using any type of backdrop you need!
That's how your local meteorologist does the weather report. They're in front of a blue screen and the camera digitally replaces it and inserts your local weather map. They're looking at themselves on the monitor to see where to point and so on. It really is perplexing and more difficult than you might imagine to be a weatherman!
Secondly…Why blue or green?
Generally we have a tendency to work with blue and green since they are the farthest from the colors found in skin coloration. The procedure was primarily accomplished by blue, however as the standard of cameras improves, green appears to work better. It's a lot easier to strip from the background, consequently most studios are switching to green. Nevertheless it doesn't do any harm to have both of them.
An added advantageous advantage for green is that it generates less apparel conflicts.
Considering that color is mechanically eliminated and replaced, if the model is wearing a shade of that color (blue) as part of their outfit…it will be substituted. You'll frequently see shirts and ties that turn into strange looking holes in the model - showing through to the new background.
It has even occurred with blue eyes!
Green tends to bring about not as much of a apparel conflict, it happens to be simpler for your cameras to work with also it's simpler and easier to light uniformly.
Uniform light is vital since shadows falling on the background will appear in the end effect. This can destroy the realism of the photography background. And also, using irregular illumination, you'll create various shades of the color…a number of which might not get stripped out correctly.
The three primary forms of green screen backdrops are: paper, paint and fabric.
Paint is useful when you have a studio having a cove and you do all your photos there…it is useless if you ever need to go on location.
Paper is available in big rolls, but is easily torn and always needs to be replaced. This can get costly in a hurry.
Cloth tends to stay fresh longest and is movable. Plus material is easy to wash (unclean green screen backdrops don't work well).
Any material store can provide some material that will accomplish the task. Get a little and do some experimenting with your photography background, any photo editing program can take out the color. Try it, you'll like it!
