Viewed at 100%, things shift in favor of Gigapixel AI. I do not have a problem with the noise and actually believe it adds more to the photos. I actually like the results from Luminar 4 better because they preserve more detail.

JPEG upscaled to 2500 px and exported from Luminar 4Ģx output from Gigapixel AI with the best settings (Art, 100 deblur, 0 noise reduction)Īt normal viewing size, all images look close to each other. The crops do not match exactly but it doesn't bother me.ġ:1 crop of the 16MP RAW file, processed in Luminar 4 I also used the Art setting because the default Standard setting introduced weird artefacts, as did the others. The blur reduction improved sharpness and I wanted to keep noise to preserve detail as far as possible.

A 4x upscale in Gigapixel AI with the same settings as 3.For me, that meant using the 'Art' algorithm with 100 blur reduction and 0 noise reduction A 1:1 crop of the original RAW, scaled up 2x in Gigapixel AI to best results.The same JPEG as above, scaled up to 2500 px on the long edge in Luminar 4.A 1:1 crop of the original RAW, processed in Luminar 4.

The birds are rufous tree-pies (Indian corvids). I downloaded Topaz Labs' Gigapixel AI and ran a quick test to see how it compares to my Luminar 4 software.įor this test, I took a 1:1 crop from a photo taken with my Canon FD 300mm f2.8L lens and my E-M5 (mark 1).
