Photo Restoration: Adventures in Upscaling - Part 1

After finishing my big photo restoration for Katrina's family I was organizing my files and noticed a scan I missed.

The scan was fairly low resolution and the photos were only 400x700 pixels.

But I was bored and restoring photos helps me relax, so I decided to fix them up anyway—even if they did not have great fidelity.

I did my thing, and it worked pretty well.

But I have been interested in a set of photo tools made by Topaz Labs. They are known for their noise removal and upscaling apps and are praised by many photographers I follow.

Before I jumped into this A.I. suite of tools I wanted to make sure it was trained ethically with licensed images—same as how Adobe operates.

So that made me feel better about that aspect. Plus I feel this is exactly the kind of thing A.I. is great for. A tool to help artists rather than displace them.

I have used a few upscalers in the past and have had varying degrees of success. Typically they just implore various sharpening tools and try to control the chunky artifacts with denoising tools—trying to find the best balance between the two.

Two opposites trying to reach a compromise.

But I was not expecting the results I got. This is way beyond anything I have ever tried before and I had no idea the technology had improved this much.

Here are the results...

All photos will be displayed in order of original, my edit, Topaz upscale followed by extremely zoomed in crops to help you better see the effects.

Crops...

Topaz has a specific "face recovery" algorithm and I was curious if these results were only because of that.

But then I looked at this little guy and he seemed pretty sharp as well.

I was stunned at how well this was working. I was able to upscale these photos so they could be printed as an 8x10 with 300ppi resolution.

Maybe that first photo was just a fluke, so I proceeded with the others.

Santa's face was mostly obscured, but it was still able to work its magic despite that.

Crops...

At this point I felt like I was a caveman discovering fire for the first time.

This next photo is interesting because it has a very creepy clown clearly plotting to kill baby Katrina. And the clown has on full makeup, which could confuse the face recovery.

Crops...

The clown face looked great, but there were two interesting artifacts involving text.

First, there was not nearly enough information on the clown's button. So the A.I. did its thing and rendered nonsense. I found a smiley face button and just did some classic compositing.

There was also a bottle of Elmer's glue on the table and even though I felt there was enough detail to make out the words, the A.I. still struggled. So I found a bottle of vintage glue with the same label and replaced it.

And it kinda feels nice that A.I. can't do everything yet and I still have to use my problem solving skills to make the best photo possible.

On to part 2!
