Re: SPP @ 2X

I am using photozoom also.  I compared it to SPP, bicubic and stair interpolation and photozomm appeared to be the best.  However, as per a comment by Kendall, I cropped a Merrill image and printed it at 32x48 at 94dpi and at 300 dpi.  It was a very sharp flower shot by the 1770C.  I don't think you could tell the difference.  So for large prints, upsizing is questionable.  I used bicubic smoother.  If you have a decent printer you ca do it  yourself.  The size of the crop was about 5x8 and again the size of the full image was 32x48.  I have done other tests at 180 vs 300 and the results are similar.
