Comprehending The Blue Screen - Photography Background!
Are you sick and uninterested in capturing (and seeing) the identical old photos
, over and over again? You've heard rumors that "green screen" is a path to go, but you do not really understand it or even know much about it? Here is all you have to understand to utilize it as a photography background!
FirstlyWhat is it?
You'll hear the terms "green screen", "blue screen", and "chroma key" tossed about and used to mean the same thing.
Chroma key only could be defined as having a background that's one unpatterned, evenly illuminated color. The blue and green tend to be the most frequently used colors. In fact, you can actually employ ANY color - but blue and green tend to be best. I will make clear why that's the situation in a minute.
Green screen techniques can be utilized within both video and still work. You shoot someone in front of the blue screen and then later (or simultaneously working with high end video cameras) you do away with the solid color and trade it with any type of backdrop you desire!
This is how your local meteorologist does the weather report. They're just standing in front of a blue screen and the camera digitally replaces it and puts in your local weather map. They are looking at themselves using a monitor to find out where to point and so on. That's perplexing and harder than you might imagine in order to be a weatherman/woman!
SecondlyWhy green or blue?
Normally we have a tendency to use blue and green because they are the farthest away from the colors present in skin tones. The procedure was originally accomplished by blue, but as the quality of cameras improves, green seems to work more efficiently. It is a lot easier to strip from the backdrop, therefore most studios are switching to green. However it does not hurt to own them both.
An added beneficial advantage for green is that it produces fewer apparel conflicts.
Since color is automatically stripped out and replaced, if the model is wearing a shade of that color (blue) in their apparelit will be changed. You can frequently see shirts and ties that develop into curious looking holes in the subject - showing through to the new background.
It's even happened with blue eyes!
Green tends to make less of a clothing conflict, it can be less difficult for the cameras to work with and it's simpler to light evenly.
Even light is essential because shadows on the backdrop will appear in the final product. This can ruin the realism of the photography background. And, working with uneven illumination, you would get several shades of the colora number of which might not get deleted properly.
The 3 primary kinds of green screen backgrounds are: paper, fabric and paint.
Paint is nice if you have a studio that has a cove and you do all your work thereyou'll find it worthless if you ever ever have to shoot on location.
Paper can be purchased in large rolls, but is easily torn and frequently needs to be replaced. This can get pricey in a hurry.
Fabric tends to keep going best and is portable. Plus material is simple to clean (unclean blue screen backgrounds do not work well).
Any material supplier can provide some material that should accomplish the task. Obtain some and do some playing around with your photography background, any photo editing program is able to strip out the color. Take a crack at it, you'll like it!
