Miracle Enlarger

A Photoshop Action: $15 US. I've used it and it is amazing. It is an automation of the 10% increase in image size explained below. It is called Stair Interpolation. Think of the possibilities of using low-res low-cost images for print media. Or using a lower res camera and getting high res results. I can't praise this action enough.

The incremental 10% enlargement which is also used in the "Stair Interpolation" actions from Fred Miranda was rated as good as Lazcos interpolation in an article which tested several of these methods. But it is said to be less effective than S-Spline and Genuine Fractals.

Everyone can easily create an action in Photoshop that does these 10% enlargements. For example for a 200% enlargement, you need seven 10% enlargements and one 2.6% enlargement.

S-Spline is incredible! I'm always amazed at how crisp and sharp the images come out. ~Hail Thyself~ :evil:

Interpolation can work very well, up to a point. Now, go all the way down to a one-pixel image and try to enlarge from that. See what I mean? It's what Kodak used to call "false enlargement". The information just does not exist.

I am no expert on this, I generally use Irfanview or Genuine Fractals to resize, however an Overview of Seam Carving see
http://www.seamcarving.com/ caught my eye and I found Resizor, a free program at http://www.peterw.000webhost.com/resizor/
which among other techniques uses Seam Carving.
I have not had a chance to really try out the program, so cannot at this time comment with any authority.

Apologies, Resizor only uses Seam Carving to reduce image size
