recommendPart 1: What Is Resolution

Resolution is the fineness with which we can see an image or photograph. The higher the resolution, the better the picture quality, and vice versa. If a photo has a low resolution, it will appear blurry, pixelated, and generally unappealing. If a photo has a high resolution, it will be crisp and clear, and will look amazing! The resolution of a photo is determined by the number of pixels it has. The more pixels, the better the resolution, and vice versa. There are two types of image resolution: ‘Pixel’ and ‘Dot’. Pixel is the number of pixels in a single image. Dot is the number of pixels per inch. A photo may have a high number of pixels, but if it is printed at a low resolution, the final image will still seem pixelated, low-quality, and blurry.
