More about Topaz Photo AI:

Topaz Photo AI will help photographers maximize image quality faster and more accurately than ever. It will automatically detect and fix some of the most common—and important—issues that could negatively impact the overall image quality of your photos right from within your existing post-processing workflow. Topaz Photo AI accomplishes this by pairing our extensively trained AI models and deep learning capabilities with a brand new Autopilot inspector.

In many cases, Topaz Photo AI can detect and address issues that your camera, or even your own eyes, could easily miss, such as soft-focus subjects and distracting luminance noise. Topaz Photo AI’s Autopilot will not only show you the issues it has detected, but it will also automatically apply the most appropriate types and strength of repairs to maximize detail, and clarity.

The problem with improving image quality so far.

Every photographer strives to improve the objective and creative image quality with their photos. And while we know that the creative side of post-processing is where you want to spend your time, it’s equally important to ensure that your photos don’t suffer from common issues that can take your viewer’s attention away from enjoying your work.

Until now, identifying and addressing those issues—such as excessive noise or soft focus—has been manual, slow, and error-prone. If you didn’t zoom in to 1000%, you might not have noticed that your subject is slightly out of focus or that there is noise throughout the image. And fixing those issues has been a manual effort that requires you to constantly compare the effects of sliders and models on an image-by-image basis, which takes time and energy away from the creative side of post-processing. It also often requires you to hop between several applications, create (and compare) multiple versioned files of the same photo, and hope that your slider and tool selections will deliver optimal results.

That’s where Topaz Photo AI comes in.

Now, it’s as simple as loading your images into Topaz Photo AI, and that’s it! You can be confident that the files you get back will be intelligently edited to the best starting place possible, allowing you to get to the creative editing process quicker, which is what all photographers look forward to in the first place!

What is the Topaz Photo AI Autopilot?

Until now, we’ve offered three individual applications to address different image quality issues: DeNoise AI for removing noise, Sharpen AI for de-blurring soft-focus images, and Gigapixel AI for upscaling low-resolution images. While each of these apps provides remarkable results within their unique purviews, the reality is that any single image could suffer from multiple image quality issues. You may also not be completely sure which of our applications would serve you best as you try to remedy those image quality issues. After all, Sharpen AI does have some noise reduction capabilities, and DeNoise AI has some sharpening capabilities. And supporting multiple AI models in our applications makes things even more complicated, requiring you to run through different models in different applications to come up with the best results.

Wouldn’t it be outstanding if you had an intelligent system that can detect specific problems within your image and use the right tools to solve them? In Photo AI, we want to make the entire process of identifying those core image quality issues and applying the most appropriate remedies automatic and transparent. That is what we set out to build for Topaz Photo AI, and we call it “Autopilot.”
