Understanding Camera Functions Exposure Exposure or lightness and darkness in the picture is a combination of the f-stop, which is the size of the hole in the lens, and the shutter speed, which is the length of time that the shutter is open. So, if you leave the shutter open longer, you’re getting more light to the film or more light to the digital sensor, and the picture gets brighter, or lighter. If you shorten the exposure (give less light to the film or to the digital sensor), the exposure gets darker. Longer shutter speed: more exposure, more light; shorter shutter speed: less exposure, less light.
18% Grey If we have a surface which 100 particles of light fall on to and 18 are reflected off, then that surface will be a grey colour, referred to as 18% grey or middle grey. The reflective light meter in our camera tells us how to make the thing it’s pointed at to record as an 18% grey value. The reason is because it’s a constant – our meters behave in the same consistent way, regardless of lighting conditions. If we point our meter at a bride in a really white dress against a white backgroud and we point our meter at the dress… what will we get? Yes, we get GREY. Knowing this we can open the f-stop (the hole in our lens) to let in more light and capture the white wedding dress we see in front of us. Therefore, creating a proper exposure.
White Balance White balance defines what the color white looks like in specific lighting conditions, which also affects the hue of all other colors.
Shooting Photos with the BigShot 3 Modes of Shooting The BigShot has 3 shooting modes to choose from: 1. Regular 2. Panoramic 3. Stereo/3D
How Stereo/3D works Since your eyes are about two inches apart, they see the same picture from slightly different angles. Your brain then correlates these two images in order to gauge distance. This is called binocular vision. A stereoscopic motion or still picture creates two images; the right image (red) is superimposed on the offset left image (blue). This produces a three-dimensional effect when viewed through correspondingly colored filters in the3D glasses. The colored filters (red and blue) separate the two different images so each image only enters one eye. Your brain puts the two pictures back together and the image become 3D!
