I use adobe lightroom. It has an enhanced algorithm that really does a very good job at upscaling images. You might also try https://imglarger.com/. Source: over 1 year ago

I don't, but try imglarger.com, it's A.I. That scales up an image, I always get amazing results. Source: almost 2 years ago

Hey, this picture looks so cooool!! I save your original image and upload it to imglarger.com to sharpen it. Here is the result. I am not sure if it is what you want. But I think the the color and contrast is better after the image is sharpened by imglarger. Source: about 2 years ago

Image was upscaled with imglarger.com as Dall.E's output images are way too small. Source: almost 2 years ago

If you'd still like a face for your character (and maybe for them to resemble you), why not try an AI facegen like generated.photos? They have a lot of readymade shots, and you can also create your own or even get an 'AI version' of your own face. Source: 12 months ago

I think this could work wonderfully with an online anonymiser though, like this one. I've always wanted to use that site, but can we really trust that they aren't using our uploads for purposes we don't want? Passing an image through Fawkes before services like these could be a neat way to combat some of the limitations. Source: about 1 year ago

Used this resource https://generated.photos/anonymizer to upload a photo of Ripley and select from AI generated faces that are supposed to be "similar to". Source: almost 2 years ago
