I was told this trick ages ago.

If you want to get a higher res picture, try doubling the resolution and then subtract 1. For some reason, it makes the picture come out much better. I have no idea why (maybe someone can help?) but it seems to work.

So, for example, to interpolate a 1600 x 1200 - try setting PSP (or Photoshop if that does it) to 3199 - let PSP set the other value.

Another very popular trick is to upscale in small (e.g., 10%), iterated increments. So to double the size using repeated 10% increases would take 7 to 8 iterations.

I haven't read the technical reason behind why this iterative process works, ..but it does!
