Enlarge Images With Maximum Quality With Alien Skin Blow Up

SHARE THIS ARTICLE

To change image size in Photoshop, you can use an interpolation method such as Bicubic Smoother or Bicubic Sharper for resampling the pixels. Resized images often lose image quality, most noticeably when enlarged. They can display a stair step or halo around some edges, often referred to as fringe artifacts.

Alien Skin Blow Up 2 is a plug-in for enlarging images to extreme print sizes. The plug-in uses an interpolation method which increases the size of the image while maintaining smooth, sharp edges. You can enlarge 8, 16, or 32 bit images in almost any color space, including CMYK, Lab and Duotone, making this plug-in perfect for both amateur and professional photographers as well as graphic designers. You can automatically create a duplicate of the image before resizing and even control the amount of photo grain that appears in the enlarged image. Blow Up 2 includes over 100 presets for preparing photos for print, saving you time and numerous calculations of the dpi and aspect ratio involved in resizing images for print.

Alien’s Skin Blow Up 2 can resize up to the limit of 300K pixels per side. You can download a demo version of Blow Up 2 at Alien Skin.

Note: When using Blow Up’s Sharpen Edges slider be careful and try to avoid making the enlarged photo appear too smooth. You can also sharpen the original first with Photoshop’s Sharpen filters.

You can use Blow Up’s Add Grain slider to visually restore overly smooth details by applying artificial film grain. For extreme enlargements, however, you may need to use Alien Skin’s more powerful Exposure plug-in to add the correct amount of grain.
