Alien Skin Software's BlowUp is a ultra-high-quality and pretty handy nondestructive image zooming tool released as Adobe Photoshop/Lightroom's filter plugin and standalone application. Its powerful features even leave many similar software (such as BenVista PhotoZoom Pro, Reshade Image Enlarger, Inpixio Photo Maximizer Pro...) in the dust!
In some cases, we may need to enlarge an image in order to see its more details. For high-definition pictures, if just zoom in several times, its quality can still make users satisfied; But when you need to enlarge it to more than ten times or even dozens of times, that must cause a sudden drop on quality and the appearance of jagged image (also called Mosaic). As to low-resolution images, the situation is even worse.
Reshade Image Enlarger (alias: Reshade Image Resizer) is a picture magnifier application, which provides the high-quality image enlargement effect. That's you can change the picture size yet avoid the usual fuzzy, serrated edge, intensification and other issues at the same time.
If you often need to capture screen images, and wonder what kind of software is good, so, PicPick is certainly worth a try.
