There are many resolution settings in Photoshop, but here are some of the most popular ones: • Default: The default resolution setting is “Original.” This means that Photoshop uses the original image size and quality. This can be good for photos that were taken on a small screen or for photos that were taken with older software. However, it can also cause problems with photos that are large or have high resolution. If you want to use a higher resolution setting, you’ll need to set one of the other options in the “Resolution” section of the " Photoshop Preferences" dialog box. • High DPI: This setting affects how sharp images appear when they’re displayed on screens. It can be set to “High,” which makes images look more like they’re made out of glass, or “Low,” which makes them look more like they’re made out of paper. If you use this setting, make sure your computer has enough storage space to store all of your images at high resolutions. • Normal: The default resolution setting is “Original.” This means that Photoshop uses the original image size and quality. It’s good for photos that were taken on a small screen or for photos that were taken with older software. However, it can also cause problems with photos that are large or have high resolution because it doesn’t take into account how big or small your computer’s monitor is. If you want to use a higher resolution setting, you’ll need to set one of the other options in the “Resolution” section of the " Photoshop Preferences" dialog box.
