You can choose one of the pre-defined scale values or enter your own. Resize by scale lets you multiply the resolution of your image anywhere from 0.5 to 6 times the input size. There are three distinct ways to resize your image in ‘Gigapixel AI’: resize by scale, by width or by height. This can be a handy feature, but depending on the processing needed, it can take a long time. This feature will automatically render the preview after every change made. The ‘Auto-update preview’ checkbox is the first thing you should notice. You can find all the settings on your right-hand side. The before/after preview window dominates the interface. This is necessary to have a good understanding of the amount of enhancement. The navigator allows you to select which part of your image will be magnified.
But Topaz labs now have Video Enhance AI that can process them automatically. You can also process video in this way by first exporting all frames of that video and importing them in ‘Gigapixel AI’. You ‘select all’ to apply the same settings to all images or uncheck ‘select all’ and choose one image, or a handful of images, and apply different settings to each image. You also have is also a batch processing function. You can also drag-and-drop images from the desktop or a folder. You can click open and import a single image, or multiple images into ‘Gigapixel AI’. Time to look at the ‘Gigapixel AI’ interface and learn more about the functions available. This is a continuous process, and every software update the engine gets better. Over time, the software learns what is missing or different and learns how to recreate or enhance these missing bits. This is a lengthy process of feeding the application thousands of images with normal and downscale resolutions. With Topaz ‘Gigapixel AI’, this also involved machine learning. Up-scaling engines like this have evolved in the past few years. Take a gander at this letter ‘W’ that I processed so you can understand what ‘Gigapixel AI’ does at a most basic level. The software does this by filling in the blanks, so to say. In comes ‘Gigapixel AI’ to upscale that crop up to 6 times. Details looks fine at first, but when you zoom in you see that it looks blurry. You cropped the hell out of that 16 MP sensor image and now you’re left with a 1,2 MP cutout. Say you’ve gotten a fantastic image of a bird-in-flight, but your tele-zoom just wasn’t long enough. Since printing images is more or less going out of fashion, maybe a better, more modern use case would be up-scaling a cropped image. It’s always possible to export an image to a larger size in an application like Lightroom, but you’ll notice a loss in sharpness and overall quality. You can use it to enlarge full-sized images to print them larger or to upscale your low resolution images.
Topaz ‘Gigapixel AI’ is an application made for photo enlargement.
