![]() If you started with a lower-quality JPEG, exporting it as High or Maximum won’t magically make it more detailed-the original fidelity is lost. ![]() ![]() ![]() (Many image-editing packages provide an interactive export dialog that previews an image as you adjust settings for quality and resolution, including the estimated resulting file size in bytes.) You can have an image with enough resolution to make a billboard from, but the quality could be so low that a lot of detail is lost. Quality determines how crisp or authentic to the original the exported file appears. Quality is distinct from resolution: Resolution describes how much information was captured in the image it’s a description of the level of detail. The lower quality you choose, the blurrier and more pixellated an image appears when you’re looking at an image at 100 percent. With JPEG, however, you can pick an option in JPEG Quality that reduces file size by having less perfect fidelity to the original image. With PNG and TIFF exports, all the detail of the original is preserved, and there’s no option for lower quality. No matter what format the image was in when imported, you may select among PNG, JPEG, and TIFF in the Photo Kind menu.
