Over het upsampelen van foto’s is veel geschreven. Ik geef hieronder een aantal links aan die je wellicht verder kunnen helpen met het vergroten van je afbeelding naar het gewenste formaat.


Bij de laatste link staat de volgende tekst, het gaat over Stair Interpolation:
The (dark) art of upsampling
That being said, (lowers voice to a whisper) there is a very special technique for squeezing pixels into an image without losing too much quality, but one should only use it in the direst of deadline or Extreme Large Format Printing (i.e., billboard) situations. The trick is to pop open the Image Size dialog, leave Resample Image checked and choose Bicubic Smoother from the pop-up menu to its right. Next, change the document dimension pop-ups to Percent and enter anywhere from 105–110%, then click OK. Do this as many times as necessary until you get the desired pixel dimensions. This will indeed add pixels to the image with surprisingly little quality loss, and at super large sizes, no noticeable quality loss at all. With such power comes the need for great restraint, however, so do resist the urge to increase more than 5–10% at a time.

Another alternative is to download software specific to this task. Take a peek at PhotoZoom Pro 2 by BenVista or Genuine Fractals by onOne Software . Both of these applications perform some pretty amazing image enlargement voodoo.

That’s all for now, and I hope this article has helped to clear up whatever resolution confusion you might have had. Until next time, may the creative force be with you all!
