Have you gotten to the point of being sick and bored with capturing (and seeing) the same old photography, time and time again? You've been told that "chroma key" could be the path to go, except you do not really understand it or even know much about it? Here's all you'll want to be familiar with to apply it as a photography background!
Are you sick and tired of capturing (and viewing) the identical old photos,
over and over again? You've heard rumors that "blue screen" is the way to go, except you don't truly understand it or even know a great deal about it? This is everything you must know to apply it as a photography background!
Firstly…What exactly is it?
You'll hear the labels "green screen", "blue screen", and "chroma key" tossed about and used to mean the same thing.
Chroma key simply means using a backdrop that is one solid, evenly lit color. The blue and green tend to be the most frequently used hues. Actually, you could potentially work with ANY color - however green and blue are best. I am going to explain why that's the case in a minute.
Chroma key strategies can be used within both video and still photos. You photograph someone in front of the green screen then we later (or at the same time working with high quality video cameras) you remove the solid color and replace it with anything you need!
That's the way the local meteorologist does the weather report. They're in front of a green screen and the camera digitally deletes it and replaces it with the local weather map. They are looking at themselves using a television monitor to find out where to point and so on. It really is confusing and more difficult than you may think to be a weatherman/woman!
Second…Why use blue or green?
Usually we tend to utilize green and blue since they are the furthest from the colors found in skin tones. The procedure was at first accomplished by blue, although as the quality of cameras improves, green tends to work more efficiently. It is less difficult to strip from the background, thus nearly all studios are switching to green. Nevertheless it does not do any harm to possess both.
Another beneficial point for green is that it results in less apparel conflicts.
Considering that color is automatically deleted and substituted, if the subject is wearing a shade of that color (blue) as part of their clothing…it will be replaced. You can often see shirts and ties that develop into humorous appearing holes in the subject - showing through to the brand new background.
It's even happened among blue eyes!
Green tends to bring about less of a apparel conflict, it is less difficult for your cameras to work with also it's easier to light evenly.
Uniform light is essential because shadows on the backdrop will appear in the end product. This could ruin the realistic effect of the photography background. And more, employing irregular lights, you'll create altered shades of the color…a few of which might not get removed correctly.
The three chief sorts of blue screen backgrounds are: paper, fabric and paint.
Paint is good if you have a studio which includes a cove and you do all your shooting there…you'll find it of no use if you ever ever would like to shoot on location.
Paper can be purchased in huge rolls, but is easily torn and frequently needs replacing. This may get pricey in a hurry.
Fabric tends to stay fresh best and is portable. And fabric is simple to clean (unclean chroma key backgrounds do not work well).
Any fabric store can offer some cloth that can accomplish the job. Obtain some and do some experimenting with your photography background, any photo editing program can strip out the color. Experiment with it, you will enjoy it!
