Final answer:
To create a black background, use the backlighting technique that makes the subject appear as a silhouette by positioning the light source behind the subject. The camera should expose for the bright background, causing the subject to be underexposed and thus creating the black background effect.
Step-by-step explanation:
To create a black background in the project section, one approach is to use backlighting. This technique involves lighting the subject from behind. As you have learned in the lesson on 'Distracting Backgrounds', when light comes from behind the subject, the subject itself blocks the light and appears as a black shape against a lighter background, creating a silhouette. This effect is particularly useful for emphasizing the shape of the subject and eliminating distractions in the background.
To achieve such an effect, you need to position your light source, such as a lamp or the sun, behind the subject of your photograph. Make sure that the subject is between the light source and your camera. The camera should expose for the bright background, which will cause the subject to be underexposed and appear black or in silhouette.
Remember, the avoidance of distracting backgrounds and the focus on the subject can be crucial for a well-composed photograph. To master this technique, review the resources provided in the 'Explore' section and practice with various subjects and light sources in the 'Build Your Skills' section. By practicing, you can learn how to use backlighting effectively to create striking images with black backgrounds.
