Only then can we make the image look high quality-with a high-quality source image at the correct size without scaling. The image quality for a small image cannot be improved unless we have the original high resolution version to work with. The user is understandably frustrated and wonders if maybe Bluewave could work some magic on the image to fix it. The result is almost invariably blurry because there just aren’t enough pixel data in the tiny photo to look good at a larger size. What happened?
