Explanation of how camera sensors capture light and create images

Cameras capture light and create images by transforming it into electrical signals. These signals then become digital data to store as an image file. It starts with the lens, which gathers light and directs it onto the sensor. The sensor contains millions of tiny, photosensitive elements called pixels. Each pixel detects the intensity of the light and generates a signal. These signals form a complete image.

The size of the camera sensor is important for capturing accurate light and making high-quality images. Bigger sensors allow more surface area to catch light. This gives better image quality, more dynamic range, and less noise. It also means more detail and sharpness in images. Small sensors have little surface area, which can cause poorer image quality and lower performance in low-light conditions.

Plus, larger sensors give more control over depth of field and higher resolution. They let photographers create artistic effects with shallow depth of field. Smaller sensors are found in compact cameras and smartphones due to their small size and lower cost. They may not be as good as bigger sensors but still do well for everyday photography.
