FAQs

Question: What is the role of Aperture in photography?
Answer: Aperture controls the amount of light entering the camera and affects the depth of field.

Question: How does Shutter Speed impact motion in images?
Answer: Shutter Speed determines how long the camera's sensor is exposed to light, affecting the sharpness of moving subjects.

Question: Why is ISO important in photography?
Answer: ISO measures the sensitivity of the camera's sensor to light, allowing for better performance in various lighting conditions.
