With the newest PhotoAI release, v 1.4.0, and now v 1.4.2 today, there is an option called Preserve Text. I had struggled with understanding how to use it, but now that I see how it works, it makes perfect sense.

When text is resized by AI software, it tends to suffer, and the purpose of this tool is to undo the damage caused by this resizing.

For an example, I am going to go back in time and use a picture taken with a 7M pixel camera of a display at a location that has elephant seals and the text on the display is talking about the moulting process these seals go through each year. The location for those interested was near Hearst Castle in San Simeon, CA.

Image #1 is the original

Image #2 shows that it has been upscaled by 2x, and some noise removal was added, but Preserving text is turned off. You can see that the text is not perfect and there are artifacts left over from the resizing.

Image #3 shows what it becomes after Preserving Text is turned on, and the text selections are made and applied. Notice that the text is much better looking and the self induced artifacts are gone.

Viewing the downloads, then clicking the +, we can see that the smear of back disappears, the letters are sharp using Preserve Text. I have never had occasion the use this sub tool in Topaz Photo-AI. To be honest, I have always used just the quick auto feature.

What is Preserve Text effect on a color image?

Here is Pacific Bell Park in 2002, home of the San Francisco Giants. Park is now known as Oracle Park.

This picture was taken with a 1M pixel camera in the very early days of digital cameras, and in Topaz's PhotoAI, it was upscaled by 3.1x.

You can see that color has no adverse effect on it. And in fact, it even works on handwriting and even on Chinese/Japanese characters.

The very last image is a side-by-side comparison of just the scoreboard. On the left is the original blown up to the same size as the resized with Preserved Text on the right. I had forgotten who was playing the Giants that day and was able to look up Melvin Mora and see that he played for the Baltimore Orioles in 2002.
