How to upscale old images to 4K With Gemini or ChatGPT

Old pictures often give you a sense of nostalgia. Their details may fade, but the memories remain. It would be great if you could restore the images and improve the details. Previously, it was not easy to restore old images without photo editing skills or expensive online tools. However, among many applications of AI image generation, this is definitely something that anyone can use. With platforms like ChatGPT or Gemini, you can also upscale your old images with a few simple steps.

What is AI Upscaling, and how do I do it with ChatGPT and Gemini?

A typical 4K image has a resolution of around 3840 x 2160 pixels. Since these tools generate images, they can also generate pixels in them. Although no new image is generated, the pixel count increases, along with improved lighting and increased texture detail. In simple words, these tools generate and create missing details. Let’s try upscaling an image on both tools.

Use ChatGPT

1. Open a new chat on ChatGPT and upload the image you want to upscale.

2. Just copy the prompt below and paste it into the chat. Hit Enter.

• query: Upscale the uploaded photo to 4K resolution at the same aspect ratio while preserving the original subject, features and composition. Enhance textures to look ultra-realistic, enhance cinema lighting, and ensure sharp focus throughout.

3. Wait until the image is processed and the new image is generated. Download the upscaled image after processing is complete.

Use Gemini

2. Use the same prompt as above and paste it. Hit Enter.

3. Wait until the image is processed and the new image is generated. Download the upscaled image when processing is complete.

ChatGPT vs Gemini: Which result is better?

If we compare the 2 results side by side, there is a noticeable difference. The ChatGPT result looks subtle and feels like a realistic upgrade, as the details are well maintained. The Gemini result has visible oversharpening and slight distortion. This may also be due to the requests. Since both operate on different algorithms. Furthermore, you can experiment further by trying a different prompt below in both tools.
