Enlarging photos appears to be a simple and mundane task for the average user. But as a pro, you understand the ramifications of firing up Photoshop and just using the Image Size dialog box, or worse yet, just stretching an image in your page layout application. Blow Up 2, from Alien Skin Software, is a Photoshop plugin that produces high-quality image enlargements by using an algorithm which temporarily converts pixels in your photo to vectors. The results are a sharper, more detailed enlargement. Read my full review of Blow Up 2 at Macworld. Blow Up 2 isn’t for everyone, but if you do a lot of image enlargements from low resolution or small high resolution images, Alien Skin has a pretty good solution with Blow Up.
