I've been using this process for a while to perform image enlargements in Photoshop, and I thought I should put it up on the blog.
After you've enlarged your image:
1. Use the Despeckle command.
This will help to soften the pixelation of the image from the enlargement.
2. Enlarge the image (again) by 200%, using the Bicubic option.
3. Use the Diffuse command, with Anisotropic option.
At 200%, this option works better to improve the edges.
4. Reduce the image by 50%.
5. Use the Unsharp Mask command.
Apply about 60-75%, using a 2px radius, and Threshold 2-4 levels.
And that's it!
The result isn't always perfect, but save this action in Photoshop, and you might just find yourself saving some time cleaning up an image enlargement.
