Qimage creates the best version with a cleaner, sharper and less pixalated image. Enlarged with Gimp Enlarged with Photoshop – Bicubic sharper Qimage – Hybrid enlarged Lets see the results, you are looking at a small area in the print at 200% resolution or zoom in Gimp. I started out with the native resolution Sigma file and enlarged them in Gimp, Photoshop and Qimage. How well will the open source Gimp performe up against Photoshop CS2 and Qimage (version. But what if I wanted to make a print 63x42cm? Enlarging a digital SD-14 file from 2640×1760 pixels (4.6mp) to 7500×5000 pixels (36mp) is no problem for Foveon but I need a program to enlarge the print. The Sigma Foveon digital files do enlarge extremely well and outperform other cameras with higher Megapixels count. Most of the time I am not enlarging my prints by that much but since I am using the Sigma Sd-14 Digital camera with the Foveon censor and it only has 4.6MP I have to enlarge most of my prints by some degree for printing. Unlike with traditional film which you can scan on a flatbed scanner and get incredible resolution for printing, I have to use Gimp or Photoshop to enlarge my prints for the final print size. One thing I have to do more often then not is enlarge my digital prints for printing.

It just no longer is an issue.Hér er ein grein sem ég skrifaði á gamla bloggið mitt, reyndar á ensku en læt flakka hér. Now I have no longer a need to get Qimage to work on Ubuntu via Wine. If you want to redo this test you can download the original Sigma file in it’s native resolution. The Gimp and Qimage prints are very close and I see no need to use Qimage over Gimp for enlarging photos.

I also did a print test on photographic paper via Epson 1270 printer and from a normal viewing distance it was hard to tell them apart but there is a small difference. But why bother when Gimp can produce excellent result with Sinc interpolation almost rivaling the result from Qimage. Have in mind I am using PS cs2 which is a rather old program and the new Photoshop version probably has something new when it comes to enlarging. The final output from Gimp using Sinc looks almost identical to the Photoshop version using Bicubic smoother. Qimage still has the edge but by so little. But Gimp using Sinc (Laczos3) interpolation is pretty darn close.

Qimage still creates the best version with a cleaner, sharper and less pixalated image.
