Shutter Speed: The Camera Setting that Controls Sensor Exposure Time

Think of shutter speed as how long the camera’s “eyelid” stays open when you take a photo. The shutter opens, light reaches the sensor, and then it closes again. Shutter speed is measured in seconds or fractions of a second, such as 1/1000, 1/250, 1/60, 1 second or longer. In general, a faster shutter speed …

Aperture: The Camera Setting That Controls Light and Background Blur

Think of aperture as the camera’s “pupil”: an opening inside the lens that widens or narrows to control how much light reaches the sensor. Aperture size is described using f-numbers (like f/1.8, f/5.6, f/16). Here’s the part that often feels backwards at first: The diagram below shows how the opening changes as the f-number changes. …
