I talked about this earlier in “How to upsize an image“. I went a bit further now and took a 100×100 pixels detail of a Roos Van Acker picture by Filip Naudts and enlarged it five times: to 500×500. The tool I use, Irfanview, has 6 algorithms to do resize: [...] […] If you take a low-res picture, and you want to blow it up to a higher size, there are different algorithms to do the calculation of all those new pixels.

When you take steps of 110, the interpolation is best and quality loss minimum. Don't ask me why, it probably had something to do with the algorytm. But it was something everybody did when working for a pressagency. *110 *110 *110 ... There was one good plugin for photoshop.
