Increases definition and detail, though very high values can result in images with an artificial appearance or blotches.
(Advanced) Increasing this value will make the generation more closely resemble the original image, but very high values can result in blotches or a dirtier look. Lower values give more freedom to the generation at the cost of moving further away from the original image.
(Advanced) Control the strength of your prompt and intricacy per square pixel:
- Lower Fractality: less detail, but typically resulting in fewer glitches. If vertical bands appear in your image, reducing Fractality might resolve it.
- Higher Fractality: amplifies your prompt in increasingly smaller areas of your overall image. E.g., if your image is a rose and you use "A photograph of a rose" as your prompt with a high Fractality value, smaller rose-like details may emerge within the main rose. A bit crazy, but this can be useful sometimes for artistic purposes. For intricate images, like fantasy maps, high Fractality at resolutions up to 10k can generate astonishing details like rivers, mountains, and cities suggested in your prompt.
• Illusio: better for illustrations, landscapes, and nature. The smoother one. Also good for the first pass of several upscales. Removes JPEG artifacts.
• Sharpy: better for realistic images like photographs. It provides the sharpest and most detailed images! However, it doesn't remove JPEG artifacts and can sometimes even create "fake JPEG artifacts".
•Sparkle: also good for realistic images. It's a middle ground between Illusio and Sharpy. Removes JPEG artifacts.
For multiple upscales, you can experiment: start, for example, with Illusio and finish with Sharpy to find the "sweet spot" for the style of your images.

I think this is the beginning of a beautiful friendship 🙂 Use the controls to upscale your first image!
