The upscaling works really well on images with good intrinsic detail and not too much processing – such as those from a DSLR or mirrorless camera. The Upscale and Enhance Resolution tools will often be used together.

There is a ‘processed’ look about the results, but it’s still an effective tool for rescuing or enhancing unrepeatable people shots. It works surprisingly well on people who are just out of focus or not quite sharp. The Recover Faces tool kicks in when the software recognizes faces in the frame and thinks they need fixing. Shots that were just slightly soft underwent a pretty dramatic transformation, and shots with poor focusing had variable outcomes – often with obviously processed edge detail and ‘filling in’ of the sort you see with over-processed phone images. I found that shots on the wrong side of its ‘fixability’ threshold were made worse – including any kind of double-image blur from camera shake. The Sharpen process can be spectacular or bad, depending on the image. I wouldn’t put this in the same league as DxO’s DeepPRIME XD processing. I found myself pushing the Detail slider up to maximum and the Strength slider down to zero to get results that looked smooth and crisp. The noise removal is very effective but quite aggressive by default. The results vary, depending on the quality of the image you’re starting from and its particular issues.

The recovered detail in the rocks and the leaves, top right, is pretty remarkable. This is the most spectacular outcome, though the Autopilot didn't think this needed sharpening it all, so it was done manually.
