What is a Digital Camera?

• A digital camera is a device that enables us to capture and store photos and videos.
• Inside a digital camera, there is a small computer that helps in the process of capturing and saving images and videos.
• One of the key components of a digital camera is the lens, which functions similar to the human eye, allowing light to create a picture inside the camera.
• Additionally, there is a sensor inside the camera that captures the image produced by the lens, which is then saved with the assistance of the internal computer.

Taking a Digital Photo

• When we want to capture a photo using a digital camera, we "take" a photo by pressing a button known as the shutter.
• The shutter button, whether physical or on the screen, initiates the process of capturing an image.
• Similar to how our eyes blink, pressing the shutter causes the camera lens to open and close, capturing whatever is in front of it at that moment.
• The image captured by the lens is then converted into a digital photo by the sensor and stored in the camera's memory.
• For instance, taking a photo of oneself using a digital camera is commonly known as a "selfie."
