Greetings,

A very industrious person has compared all the major competitors in this arena, including Lanczos interpolation, and made the visual results available here:

This is the best comparison I have discoverred anywhere.

Hope this helps.

It is great, I have been using it since May 2001. I have the original one from Altamira Group. I was shooting with A Nikon 990 and croping and printing up to 13 X 19 with no problems using this program. I believe they probably even improved it over the last few years. I would not see how though.
I don't use it much anymore because I now use a Nikon 8700 or My D-100 and I have enough camera resolution to do what I need to do.
It is there when I need it though.

If you have Photoshop it is easy to set up an action for stair interpolation. I like it at least as well as GF and it is free. Fred Miranda has a more sophisticated action for accomplishing it that is very inexpensive, but I haven't compared it to the simple SI.

I use 5% increments for SI. I have an action that runs five 5% increments and one that combines four of the basic actions. I can hit pretty near where I need to be with the combination.

Here is an upsample with SI compared to bicubic one step I made a couple years ago. It is only about 5% of the total image so it is grainy. But I needed something low resolution to test the effect.
