General Green Screen / Chroma key Information
Chroma key compositing, or chroma keying, is a visual effects/post-production technique for compositing (layering) two images or video streams together based on colour hues (chroma range). The technique has been used in many fields to remove a background from the subject of a photo or video – particularly the newscasting, motion picture, and video game industries. A colour range in the foreground footage is made transparent, allowing separately filmed background footage or a static image to be inserted into the scene. The chroma keying technique is commonly used in video production and post-production. This technique is also referred to as colour keying, colour-separation overlay (CSO; primarily by the BBC), or by various terms for specific colour-related variants such as green screen, blue screen and magic pink; chroma keying can be done with backgrounds of any colour that are uniform and distinct, but green and blue backgrounds are more commonly used because they differ most distinctly in hue from human skin colours. No part of the subject being filmed or photographed may duplicate the colour used as the backing, otherwise, the part may be erroneously identified as part of the backing.
It is commonly used for weather forecast broadcasts, wherein a news presenter is usually seen standing in front of a large CGI map during live television newscasts, though in actuality it is a large blue or green background. When using a blue screen, different weather maps are added on the parts of the image where the colour is blue. If the news presenter wears blue clothes, his or her clothes will also be replaced with the background video. Chroma keying is also common in the entertainment industry for visual effects in movies and video games. Rotoscopy may instead be carried out on subjects that aren't in front of a green (or blue) screen. Motion tracking can also be used in conjunction with chroma keying, for example to move the background as the subject moves.

Looking after your camera
Use a Camera Bag
A camera bag does more than just protect the camera against scratches and dust: It keeps it safe from rain because many are waterproof on the outside.
Be Very Careful Around the LCD Screen and Camera Lens
Use only special equipment to clean your camera’s LCD screen and camera lens. Buy a special cleaning kit that includes liquid solutions, microfiber cloths and brushes that have been specially designed to clean your camera lens.
Never Leave Your Batteries in Your Camera for Too Long
Many camera batteries are now alkaline or lithium formats. If you keep your camera with the batteries inside of it in a moist area, then the batteries can get corrosive. So if you’re thinking about just putting your camera on the shelf for several months, do yourself a favor and remove them.
Turn Your Camera Off Prior to Doing Anything
Before you do anything to your camera, always keep in mind that it should be turned off first. No matter what it is—swapping lenses, changing memory cards or disconnecting or attaching cables—your camera should be turned off.
Cold and Wet Weather Can Wreak Havoc on Your Camera Body
Take your camera out only in a waterproof bag. If the weather’s unusually cold, just wrap your camera in a plastic bag that has silica desiccant packets for the reduction of moisture. It’s also a smart idea to have a soft towel with you to wipe off any moisture, just in case it should get on your camera.
Good Memory Card Care Is Good Camera Care
Only transport your memory cards inside of a protective caseMake sure the memory cards stay dust-free at all times. When removing memory cards, make sure you do so indoors or in non-dusty situations.
Make sure that you keep memory cards only in cool places. Never keep them in places where they may heat up, like dashboards or glove compartments.
Never place your memory cards close to magnetic sources. Examples of magnetic sources are things such as audio speakers, TV monitors and actual magnets.
Use a Filter to Protect Your Camera Lens
The lens of your camera is naturally fragile. As such, it’s susceptible to scratches, cracks, dents…you name it. A UV filter will not only will you give your lens a fighting chance, but you’ll also enhance the quality of your pictures.
Condensation Can Be Controlled
Condensation normally happens when you move your camera between different temperatures.
Allow your camera a chance to naturally get used to the hotter environment. Don’t place it inside a closed plastic bag when transporting it between different temperatures! Just let the camera sit in the humid temperature for a while, until condensation disappears.
If this still doesn’t get rid of all of it, you can utilize a soft cloth to wipe away any remaining moisture and marks left behind from the condensation.
