A megapixel is equivalent to one million pixels and is a common measure of a digital camera sensor's resolution. The higher the number of megapixels, the greater the potential image detail and quality, allowing for larger prints and more flexibility in cropping.
Understanding megapixels is important for photographers and digital imaging professionals who want to evaluate camera performance and image clarity. While higher megapixels can improve resolution, overall image quality also depends on factors such as sensor size, lens quality, and image processing technology.
