SUMMARY
AI upscaling technology has advanced to the point where 11-megapixel files can be enlarged for fine art prints with surprisingly good results. Keith Cooper's examination shows that while upscaled images appear "plausible" and the distinction between real and synthesized detail is minimal at viewing distance, the quality of the input file is crucial. Pre-processing the raw file, for instance with DxO PureRAW, results in a sharper input for the upscaler, leading to a more detailed output. Cooper finds AI upscaling acceptable for landscapes but draws a line at extending image frames and warns of unsettling results with distant crowds.
TAKEAWAYS
AI upscaling allows large prints from low-resolution files, making detail "plausible" at viewing distance.
Input file quality is critical; upscaling amplifies existing detail, not corrects softness.
Pre-processing raw files significantly impacts upscaling results.
AI upscaling is suitable for landscapes but has limitations for image extension and distant crowds.
