I got an email notifying me of the release of Topaz Sharpen AI, a program that enhance details and fix out-of-focus/blurred shots. I initially expected that it was something similar to Adobe Enhance Details, which slightly enhanced the details of some specific shots and didn’t work for many other images. Topaz provided a demo fully-functional for 30 days, so I decided to give it a try. Honestly speaking, I didn’t expect much. AI is the buzz word these days. Every company claims that their products feature wonderful AI but usually such AIs underperform my expectations. I tell you the conclusion first so that you don’t have to waste your time. I was very very impressed with Topaz Labs’ technology. It doesn’t work perfectly well with all images and it has some drawbacks, but the overall technology is really AMAZING. Let me show you some images I processed using this software. The first example is a landscape photograph I took during my travels in Australia. It was a typical situation for travel photographers: I had to take this photo with my 28-300mm utility zoom lens. There’s no problem with the focus or camera shake, but it was simply that the lens was soft particularly at the edges. Before/after at center Before/after at edge I was blown away. The following settings were applied. If you feel it’s a little too sharp at the center, turn Remove Blur down to, say, 0.40 and blend them together in PhotoShop using the circular gradation tool on a layer mask. As soon as I started using this software I noticed something unusual — It is really slow! This program is extremely CPU/GPU intensive, so you need to run it on a fast PC. My 27″ Retina iMac is not too slow (Core i7 7700K 4.2GHz with Radeon Pro 8GB and 40GB of RAM), but it runs really slow on my computer. If you turn off Automatically Update Preview switch at the right bottom of the window, it runs smoothly but you need to check out the preview to make appropriate settings. The workaround I found was to keep the preview size as small as possible — then it ran a little faster. Still slow but somewhat bearable. OK let’s move on to the next example. This photo was again taken with a utility zoom lens. I took this shot when I lived near the building (Tokyo Metropolitan Government Building) several years ago. The original image was slightly out of focus. Perhaps I should’ve fixed the purple fringe in Lightroom in advance. But the Sharpen AI enhanced the details dramatically and also removed the purple fringe to some degree. original size before/after at the center original size before/after at the edge So far this program is really amazing. But it doesn’t always work perfectly well. This shot was taken with the SIGMA ART 50mm F1.4, so it’s actually very sharp and doesn’t really require any further sharpening ,but I tested it, too. Before/after around the center Before/after at trees in the shadows (brightened a little to make them more visible) The AI successfully sharpened the image except for the trees hidden in the shadows. The original was much better in this particular area. So you need to know how to blend two images using a layer mask in Photoshop to fully appreciate this software. How does it work on photos with a shallow depth of field? I tested the AI with the above example shot. Before/after around the center Before/after in the defocused area To my surprise, it sharpened the focused part and also smoothened (or reduced the noise at) the defocused part. The focused and defocused areas were easily distinguishable in the above example. Let’s try it with another sample in which the amount of bokeh varies within a single subject. You might wonder why I couldn’t focus on a cat who stayed still. Well I manually focused using an old lens… It’s a shame to show you such a badly taken photo but it is a good example for the review. This settings couldn’t fix the focus. So let’s try another algorithm. A little better. But not very natural. Maybe you can blend it with the original to make it look as if the focus is on the nose of the cat. I need to test more photographs to draw a conclusion but I guess that the AI is not very good at handling this sort of photographs, that is, the amount of bokeh varies dramatically within a single subject. The last example is a photo of an eagle I took in Australia with the 28-300mm utility zoom. I spotted an eagle while driving in the outback. I quickly pulled over the car and took this shot but unfortunately the camera couldn’t AF well. Wow! I was utterly gobsmacked at the result. It’s magic! isn’t it? But it also sharpened defocused areas in an unnatural way as well. So I’d need to blend the sharpened image with the original in Photoshop. I don’t explain how to blend them in Photoshop in this article, as it is already too long and I want to focus on the AI. BOTTOM LINE: This product doesn’t work perfectly for every photo but works wonders on many photos. I highly recommend Topaz Sharpen AI if you have a fast computer. I bought it. I would be delighted if I could use PayPal though.
You’d need a fast computer to use this software.
