It is a much better alternative than a seperate noise reduction after Gigapixel processing! For scaling I have only used the 2x setting, Labs: more AI, please! If the blur is stronger, Gigapixel will not sharpen it, else it will! If the original piece of film was curved or wavy (a typical problem for digitising), you might need the highest setting! Simply try! The "Suppress Noise" setting is very effective. In my opinion the "Remove Blur" setting defines a kind of threshold value for blur. The screenshot on the right shows the ones I used for the image of Siglufjörður. Gigapixel AI only has very few settings options. I will wait for the next version of Sharpen AI. Moreover, the processing times are even longer. But I didn't get results as good as those from Gigapixel AI.

The results of traditional unsharp masking are not comparable with the results of Gigapixel AI! I also downloaded a trial of Topaz Labs' Sharpen AI. I bought a regular version of Gigapixel AI and I am happy that a lot of my slides are really back in the game now!

Examples are most of my slides from the 80s on ISO 400 Fujichrome RH film. But there is one restriction: for very noisy images the output of Gigapixel doesn't really look good. Of course, I tried many digitised images of different ages and different subjects - see some examples below. What can I say - the result has blown me away! Compare the 100% crops below for yourself: The processing time was around six minutes. Now, processing took around 10 minutes! Then I compared the result at 50% with the original at 100% - again, just minor improvements! Last try: I downpixelled the original image by a factor of 2 in Photoshop Elements! Then I put Gigapixel into service with an upscaling of 2x.
But the result disappointed me - it was just a slight improvement, like a standard sharpening. Gigapixel just needed one second for processing. My first approach was to use a custom scaling of 1x. Moreover there is an option for custom scaling in the range from 0.5x to 6x. Gigapixel allows a scaling of 0.5x, 2x, 4x or 6x. I downloaded a trial version and tried to improve the image above. Topaz Labs has just introduced version 4.0 of Gigapixel AI. The output of your DSLR contains more details and is sharper! If you view this image fullscreen on a typical 24" 1920x1200 monitor, it looks a bit soft all over. That is enough pixels for me, but in fact the image is only usable for prints up to about 30x20cm. Such images have about 3600x2400 pixels, due to the optical resolution of my scanner of a bit more than 100 pixels per mm. 12 years later, I scanned the slide with my Nikon Coolscan III. In June 1989 I captured this image on ISO 100 Fujichrome RD slide film.
It shows the little fishing village of Siglufjörður in northern Iceland. However, I found Gigapixel to be a great and easy-to-use tool for improving digitised images.īelow, you can see a typical digitised image of mine. If your image doesn't contain enough pixels for printing/viewing it in the size you want, Topaz Labs recommends the usage of Gigapixel AI. Here, AI-driven means the additional pixels are not just interpolated, they are set by the neural network of Gigapixel AI that has learned its job through thousands of real-world images! Gigapixel AI from Topaz Labs is a stand-alone postprocessing tool that offers AI-driven image upsampling. Photography is no exception - think of the face detection in your camera for example. More and more, our daily life is surrounded by AI helpers. Topaz Labs Gigapixel AI 4.0 - artificial intelligence for digitising!
