 Welcome to Getting Started, the Sikonic Light Meter. There are many light meters available nowadays, but the Analog Sikonic is still a preferred quality light meter used by photographers and cinematographers around the world. This light meter makes it easy to get accurate exposure in any ambient light situation by helping you find the f-stop you should set your lens aperture to. A low f-stop, like f2.8, means the aperture is wide open because what you are filming is dimly lit. A high f-stop, like f11, means the aperture is closed down because what you are filming is extremely bright. How it works. It does not need a battery or even to be plugged in. This light meter uses an amorphous photocell that generates enough electricity to power the device. Just take it out of the case and it's ready to use. It makes light measurements using a simple meter needle. The measurements are then transferred to a computer dial for exposure settings. Before making readings, press and turn the silver stopper button in the center of the dial until the dot is top dead center and the button pops up when you lift your finger off of it. To do an ambient light meter reading, first set the ISO on the light meter. Check the ISO of the film stock you are using. Set the ISO by placing your finger on the raised pattern near the silver stop button and moving the dial until you see the corresponding number in the ISO window. The Lumisphere is the round white part of the meter and is made that way to simulate a three-dimensional face. Reset the light meter by covering the Lumisphere with your hand and pressing the button. For incident readings in normal indoor situations, point the Lumisphere in the direction of the camera from the subject's position. Press the silver stopper button to allow the meter needle to move to indicate the amount of light present. Release pressure on the silver stopper button when the needle stops to trap the needle in place. Now grasp the outside of the dial so the red marker lines up with the meter needle. Next, turn the black dial ring so that the black pointer on the computer dial lines up with the same foot candle value that is indicated by the needle. You are going to be using this meter for motion picture, so refer to the orange numbers near the center of the dial next to the word Cine. These represent cinema camera frame rates. The aperture number on the outer dial that is directly below the frame rate number is the proper F-stop for that frame rate. Now set the F-stop on your lens and you are ready to shoot. Let's recap. First, match the ISO settings on the light meter to the stock of your film. Second, point the Lumisphere in the direction of the camera from the subject's position. Third, press in the silver button and release to take a reading. Fourth, turn the dial on the light meter to match the foot candle measurement. Last, match your desired frame rate to the meter's recommended aperture settings and set your camera according to the number on the meter. When measuring light in bright outdoor conditions, insert the high slide. The high slide is found on the back of the light meter and is slid into the top by the Lumisphere. Match the red H-arrow to the needle. Thanks for watching Getting Started.
