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. Alan |

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! More discussion on this technique can be found here: http://www.stevesforums.com/phpBB2/v...3d6fe6661aba88 |
