Image resolution, size and compression

Resolution refers to the sharpness and clarity of an image. When saving your pictures you want to decide what you will use them for. Usually you will be printing them or sending them in emails. To keep good resolution of your pictures you will need to decide on what size to save them, usually 200-300 pixels high might work. You would reduce your file size by compressing the image. When you have higher compression of your image it might be come pixelated. Formats such as BMP or TIF files do not compress the image. Using JPG compression you can keep the physical size of image, but reduce disk space by not sacrificing the quality.

Resolution also plays a part in your monitor. The larger the monitor the larger your screen resolution will be.
