Using the Image 80 to Light a Blue Screen
Blue screen compositing is better executed with a perfect photography setup using Image 80 to lighten the set. That’s why you need the best lights that are sensitive to the blue screen.
Step 1: Decide on the Theme of the Shoot
You need to finalize your theme, as it would be very important to distinguish which light set up would be perfect for it. Once you have the scene in mind, you can go ahead and setup your blue screen room. The reason that blue is used for keying is that blue is the least hue that is found in the human skin tone. The human skin tone is usually red and green, with just measly bits of blue. However, certain themes may require different setups.
For example, if you are wanting to shoot warmly lit scene, then it might separate better if you use a blue screen, but if let’s say you are shooting a bunch of people dressed as soldiers in camouflage, then blue will be perfect as the overall green in the subject could be affected if you use green.
Step 2: Decide on Whether a Blue or Green Screen Would Be best
Let us look at the technical considerations of the activity. In every clip shot using film, the finest grain structure is found in the greens. On NTSC videos, we can say that the green channel has the sampling rate that exceeds the other use. This means that if you are shooting with film, having a green screen is better because it is less grainy than blue, which means that when you edit it later, you will have fewer problems in separating the subject from the background.
Step 3: Set the Lighting How You Need It
Once you are ready to take shots, you have to mount your lights where it needs to be--it depends on how you designed your theme earlier. The Image 80 can easily be operated manually with the Manual Lamp Selector dial. This allows you to choose whether to set the inside lamps first or the outer tubes on.
The intensity of each light can also be controlled by using the DMX address switches, which determines which lamps or tubes will turn on or not. While manual controls are set to off by default, you can always set the address to “000” for manual control, which takes a 5 second delay to switch between modes.
Step 4: Final Touches to the Setup
Now that you are familiar with the manipulation of the Image 80, you can move on to the Fixture Lamp Mode which is most suitable for lighting blue or green screens. A great example would be to setup a row of fixtures set on the same address, and when the fader on the dimmer board is switched up or down, all the lamps will simultaneously turn on (enabling the flat light to cover the entire scene while the subject stands out with its unique tones from either green or blue).
Now you have setup your blue screen with the Kino Image 80, and you can now make great photographs.
