FAQs on Lecture 3 - Exposure Video Lecture - Exposing Digital Photography by Harvard Extension School

1. What is exposure photography?

Ans. Exposure photography refers to the technique of capturing an image by controlling the amount of light that reaches the camera's image sensor or film. It involves adjusting the camera settings, such as aperture, shutter speed, and ISO, to achieve the desired exposure for a well-balanced and properly lit photograph.

2. How can I adjust the exposure settings on my camera?

Ans. To adjust the exposure settings on your camera, you can use the following methods: - Aperture: Use a wider aperture (lower f-stop number) for a brighter exposure and a narrower aperture (higher f-stop number) for a darker exposure. - Shutter Speed: Increase the shutter speed to reduce the amount of light entering the camera, resulting in a darker exposure. Decrease the shutter speed for a brighter exposure. - ISO: Higher ISO values increase the camera's sensitivity to light, resulting in a brighter exposure. Lower ISO values reduce sensitivity, resulting in a darker exposure.

3. What is the "exposure triangle" in photography?

Ans. The exposure triangle is a concept that represents the relationship between three fundamental exposure settings: aperture, shutter speed, and ISO. These three elements work together to control the exposure of an image. By adjusting one of these settings, the other two must be adjusted to maintain a balanced exposure. Understanding the interplay between these settings is crucial for achieving the desired exposure in photography.

4. How can I avoid overexposure in my photos?

Ans. To avoid overexposure in your photos, you can try the following techniques: - Use a smaller aperture (higher f-stop number) to reduce the amount of light entering the camera. - Increase the shutter speed to limit the time the sensor is exposed to light. - Lower the ISO to reduce the camera's sensitivity to light. - Use exposure compensation to manually adjust the exposure level. - Make use of filters, such as a neutral density filter, to reduce the amount of light entering the lens.

5. What is the importance of proper exposure in photography?

Ans. Proper exposure is essential in photography because it directly affects the overall quality and impact of the image. Underexposed photos may appear too dark, lacking detail and definition, while overexposed photos may be washed out, losing highlight details. Proper exposure ensures that the subject is well-lit, colors are accurate, and shadows and highlights are well-balanced, resulting in a visually pleasing photograph. It also allows for greater flexibility in post-processing and editing.
