Understanding Image Resolution
Image resolution refers to the amount of detail an image holds. Higher resolution means more detail and clarity, while lower resolution can result in blurry or pixelated images. When you increase the resolution of an image, you are essentially enhancing its quality, making it suitable for various uses, such as printing, web design, or social media sharing.
