Which is the best upsizing method is discussed over and over again in many news groups. We launch this upsizing contest to learn from the shared experience of all our readers.

To share experience it is not enough just to show the results. We need precise step-by-step descriptions of all image editing operations that had been performed. That is why we need to limit the used tools to the ones that are available at Digital Outback Photo (and they have to be available for PC and Mac):

  • Photoshop (this is the standard image editor we use)
  • Genuine Fractals
  • Fred Miranda's stair interpolation
  • PowerRetouche Sharpening
  • Nik Sharpener Pro
  • PhotoKit sharpening tools
  • Other tools (if the tool author provides a free full working copy to Digital Outback Photo)
 
Here is the original photo used (handheld with the Canon EOS 1Ds + 24-70mm f/2.8 lens and converted with the Canon Fileviewer Utility with no sharpening)
 


Purple Victorian in Los Gatos

 


Crop 1 (not sharpened)

Crop 2 (not sharpened)

 
Here you can download the crops (16 bit TIFF in a ZIP file).
 
We will finally vote for a winner. Besides getting into the contest hall of fame the winner will receive also a free copy of ThumbsPlus 5.
 
Contest Rules
 
  • Download original crops (1 = 250x150 pixels, 2 = 150x100 pixels)
  • Upsize crop 1 to 500x300 pixels and crop 2 to 300 x 200 pixels with the ssame method
  • Perform sharpening (same sharpening for both crops)
  • Converted to 8-bit
  • Email us back in a ZIP file
    • A JPG of the upsized crop (just for our info)
    • Detailed instructions of your work (using only above mentioned tools)
    • Your name, email/web address (both optional)
  • Contest ends 2/15/2003

We then will publish on this page your results.
