When you press the shutter button on a digital camera, light enters through the camera’s lens and is focused onto an image sensor. The image sensor consists of millions of tiny photosensitive cells called pixels, which detect and measure the intensity of light that reaches them.

Once the image sensor has captured the light, it converts the data into electrical signals. These signals are then processed by a digital signal processor (DSP) inside the camera. The DSP applies algorithms to the raw data, enhancing and optimizing the image quality.

After the data has been processed, it is stored on a memory card inside the camera. The memory card acts as the camera’s digital film, allowing for the storage and retrieval of multiple images. The size of the memory card determines how many photos can be stored.

To view the photos, the data is transferred to a computer or displayed on the camera’s LCD screen. On a computer, specialized software can be used to edit and manipulate the images further.

In conclusion, digital cameras work by capturing light through a lens and converting it into electronic data. This data is then processed and stored, allowing for the creation and sharing of digital photographs.
