Have you gotten to the point of being sick and bored with capturing (plus seeing) the identical old photography, over and over again? You have heard that “chroma key” is the way to go, however you don’t really comprehend it or even know much about it? Here’s everything you must know to apply it as a photography background!
Firstly…What is it?
You’ll hear the labels “green screen”, “blue screen”, and “chroma key” thrown around and used interchangeably when discussing a photography background.
Chroma key simply means having a backdrop that’s one solid, uniformly lit color. The blue and green are the most frequently used hues. Actually, you may choose to employ ANY color - however blue and green are easiest. I’ll explain why that’s the situation in a second.
Green screen techniques can be used during either video and still photography. You shoot somebody in front of the green screen and then we later (or at the same time with high end video cameras) you eliminate the solid color and replace it using anything you would like!
This is the way the local meteorologist does the weather report. They’re just in front of a chroma key and the camera digitally deletes it and puts in the local weather map. They’re just looking at themselves with a monitor to find out where to point and so on. It is perplexing and more difficult than you might envision in order to be a weatherman/woman!
Secondly…Why the colors blue or green?
Normally we tend to make use of blue and green since they are the furthest away from the colors found in skin coloration. The technique was initially done with blue, however as the standard of cameras changes, green seems to work better. It is a lot easier to strip out of the backdrop, therefore almost all studios are switching to green. Nevertheless it doesn’t do any harm to have them both.
An added good advantage for green is that it creates fewer apparel conflicts.
Since the color is mechanically deleted and substituted, if the subject has on a hue of that color (blue) in their outfit…it’s substituted. You’ll time and again see shirts and ties that become curious looking holes in the subject - showing through to the brand new background.
It’s even occurred among blue eyes!
Green tends to produce not as much of a apparel conflict, it happens to be less complicated for your cameras to work with and it’s easier to light uniformly.
Flat light is vital since shadows on the backdrop will show in the end result. This tends to damage the realistic effect of the photography background. And also, employing irregular illumination, you’ll create various shades of the color…several of which might not get removed correctly.
The three major sorts of blue screen backgrounds are: paint, fabric and paper.
Paint is nice if you have a studio using a cove and you do all your photography there…it can be useless in case you ever need to shoot on location.
Paper is available in big rolls, but is easily torn and regularly needs replacing. This can get expensive in a hurry.
Material tends to last ideal and is movable. And fabric is easy to clean (unclean blue screen backgrounds won’t work well).
Any fabric supplier can offer some material that could accomplish the work. Obtain some and do some testing with your photography background, any photo editing program can take out the color. Take a crack at it, you’ll enjoy it!
