This dinosaur image was generated by me using Gemini, with an original resolution of only 1344 x 768px. On the right side, there are five upscaling models suited for different purposes. Below is the magnification scale; the free version lets you choose 1x, 2x, or 4x:
- Photo: Images of people, nature, architecture, etc. captured with a phone or digital camera. Compared to the standard model, the results are softer.
- Anime: Suitable for AI art, illustrations, painting, animation, and cartoons. Can apply painting effects to photos.
- Standard: For landscapes, city skylines, and other snapshots.
- Iris: Emphasizes high-contrast details in eyes, fur, hair, feathers, and similar features.
- Business: Makes text, real estate images, digital art, and product photos clearer. Longer processing time.
