Megapixels: The number of megapixels determines the resolution or quality of the image captured by a digital camera.
Shutter Speed: Shutter speed refers to how quickly the camera's shutter opens and closes, affecting the amount of light that enters and how motion is captured in a photograph.
ISO: ISO measures the sensitivity of your camera's image sensor. Higher ISO settings are used in low-light situations to capture brighter images, but they can also introduce more noise or graininess into the photo.
