[QUOTE="pforsell, post: 677633, member: 7240"] I shot an image with an ancient Nikon D1H. The original image is 2.7 mpix. Then I tried the Photoshop CC "Preserve Details 2.0", OnOne Raw 2018 Resize (nee Genuine Fractals) and finally AI Gigapixel. I increased the image size 200% to 10.5 mpix. What is obvious is that none of the resizing tools is able to extract any real details - see the text on the battery, it is illegible. The upsizing methods invent fake details either by using fractals or a neural network with a huge image library, but the fakeness is obvious. The final line is: there's no substitute for more pixels. Better to either use another camera or do multi-image stitching. I'll save my monies and pass these utilities. It's disappointing the "neural net" AI Gigapixel didn't recognize the Varta Battery and replace the mushy text with a sharp copy from the allegedly "huge image library." If it had managed to provide readable sharp text, I'd given my 100 bucks. But as it is, sorry, no go. None of the images looks like a real 10.5 mpix photo to me. The positive thing is all the uprezzing methods were quick at this small size, about 2 seconds to go from 2.7 to 10.5 mpix.
