Post Description

Plugin Blow Up for Adobe Photoshop offers the highest quality image resizing available, better than bicubic interpolation 
and any other third party solution. 
Blow Up makes advanced image scaling easy, preserves smooth, crisp edges and lines, and creates four times 
(1600% area) enlargements from any image without jagged artifacts or halos. In some cases, 
Blow Up can enlarge up to six times (3600% area) without obvious artifacts.
