Topaz Gigapixel AI 5.2 Released – Review
Gigapixel AI 5.2 What’s new?
Topaz are now producing incremental updates rather than going for the big annual release. The advantage of this is that, for those with a support contract, you get a steady stream of enhancements rather than having to wait a year for the next big release.
This latest release features:
- A new Crop tool to crop your image without leaving Gigapixel AI
- A new “Compressed” AI processing model trained to enlarge photos with artifacts and compressed images downloaded from the internet
- A UI overhaul to give Gigapixel AI a new aesthetic and more consistency
- Faster previewing and saving of images
This posts focuses on the second feature – the ability to upsize a compressed or noisy image. I took one of my noise test photos, downsized it to 2048 x 1366 pixels and then:
1) Upsized it to 4096 x 2732 in Affinity Photo
2) Used Photo Ninja (one of the best non-AI noise reduction programs) to remove the noise and then upsized it to 4096 x 2732 in Affinity Photo
3) Opened the picture in Gigapixel AI v 5.s and upscaled it to 4096 x 2732 using the new noise reduction mode.
In all cases, I saved the result as a TIF file to prevent introducing JPEG artefacts into the result.
You can see how I did this in the following video:
Topaz AI Gigapixel 5.2 Test
It is no surprise that the result of step 1) is terrible – after all, upscaling a noisy image can only make things worse.
Noise Ninja’s results, on the right, demonstrate the best ‘ordinary’ noise reduction + upscaling. Compared to the original, noisy, image it is certainly a big improvement.
Let’s see what Gigapixel AI 5.2 can do (Gigapixel’s results on the left, compared to Ninja + Affinity on the right)
Gigapixel AI v 5.2 has produced a fine result – the noise has gone and there is far more detail in the image. It has removed the obvious chroma noise speckles without removing too much colour. The image is not a smooth as the Photo Ninja one, but the extra detail more than compensates for this.
Gigapixel AI 5.2 Conclusion
This is only a brief test of what Gigapixel AI 5.2 can do – for a more in-depth look at it see these previous blog posts:
Topaz keep on enhancing Gigapixel AI. V5.2 is another fine update that makes this tool indispensable to me. Gigapixel AI is the best tool that I have tested for upscaling an image. Even relatively small enlargements benefit from the Gigapixel treatment. It is the only tool I would consider for massive enlargements.
