Вот фото, но оно не очень хорошего качества. Повыс...

Scaling and processing image

I’m planning to resize the image to a max width of around 2000-3000 px, computing the scale factor based on the width. If it’s in grayscale, I’ll leave it as it is. Then I’ll apply some quality-enhancing filters like an unsharp mask, ImageFilter.DETAIL, and possibly SMOOTH, sticking to PIL for compatibility.

Upscaling & processing image

To upscale, I’m choosing a target width of 3000 px or 3x the original width, depending on the image size. For denoising, I’ll use a median filter, then sharpen with an unsharp mask. I’ll save the image in PNG or WEBP format to keep the quality intact, as the user wants high quality.

Saving and presenting image files

The user wants the image quality preserved, so I’ll save it in PNG. Since the environment requires links to the created files, I’ll save both PNG and JPG versions and provide download links. I’ll also add a side-by-side preview to show the results—though that might not be essential.
