Masking in photography can sometimes be a time-consuming task in photo editing. Topaz Labs has created Mask AI to make the masking process faster. This Topaz Mask AI review will give you a quick run-through of the software.

My Topaz Mask AI Review and Thoughts

First of all, Topaz Labs had a similar masking application called Topaz ReMask. I feel Topaz ReMask and Mask AI are pretty much the same software. So, if you were planning to upgrade from ReMask to Mask AI, I don’t think it would be worth the upgrade.

Now getting back to the newer photography masking software.

How Mask AI Works

The masking process works by you using three different colored brushes:

Green – areas that you want to keep

Red – areas that you want to cut

Blue – areas you want Mask AI to calculate

With the green, red, and blue brushes, you tell Mask AI which parts of the image you want to keep and remove. You’ll be painting a trimap.

The way I brush the mask is by first using the blue brush and adjusting the brush to a size that makes painting along the edge of the required mask easy.

After I have a good blue brush size, I paint the parts of the image where I want Mask AI to compute the mask for me. In other words, the blue painted area is the difficult part of the image to create a precise mask, therefore making Mask AI do the artificial intelligence process when I’m done painting. The blue brush is used for edge detection.

After finishing with the blue brush, I’ll use the green and red brushes to paint the areas I want to keep and remove.

If there is a large area that requires all green or red paint, then you can use the green or red fill buckets. These are like brushes but with one click on the image it’ll paint everything the color you choose. It’ll stop at the edge of another brush color.

With the below image of the woman, I first used the blue brush to paint along her body and hair.

I then used the green and red fill buckets to quickly paint the inside of the blue outline green, and outside red.

For more complex masks, such as portraits with hair sticking out or trees with a sky view between the branches, you need to refine the mask by making small brush strokes/spots in areas you want to keep and cut.

I’m not sure how much artificial intelligence Topaz Mask AI has. The term AI is used loosely and comes off as a marketing strategy.

After painting with the tricolor brushes, you just press the compute mask button. Mask AI will now calculate the mask.

Once the mask is produced, you can further edit it with the brushes plus shift and harden (sharpen) the mask.

Mask AI edge details

I used a difficult image to mask: a girl with her hair flying out.

Below is the result of my mask without spending too much time on it. As you can see, Mask AI is not perfect. Even if I spend more time on the mask, it would have been counterproductive as hair is not easy to mask even with an automation software.

In order to do a better job at masking the above photo, you would need to take it into Photoshop and use the blend modes.

There is also an auto detect sky mask tool to make masking easier. It saves some time. On the other hand, if you really want to mask the sky and replace it with something else, then you should read about Luminar’s AI Sky Replacement and AI Augmented Sky technologies.

Internet connection is required to log into the software.

Amazingly, Mask AI did a pretty good job with the cat image below. You may not notice it because of the white background, but the whiskers were masked well. I didn’t even bother fine tuning the trimap in this example.

Topaz Mask AI will easily mask high-contrast images that don’t have multiple fine or thin details.

But the application is expensive considering it only accomplishes one process of the photography workflow. There’s more value in the Creator Bundle which sells for $149.99, and includes Topaz Studio 2, Adjust AI, and Mask AI.

You can read the Topaz Studio 2 summary or Adjust AI review for more information.

But I only recommend Mask AI if you don’t use Photoshop for masking. Interestingly, it can be used as a Photoshop plugin but not for Lightroom or Capture One.
