Perhaps this trick may be useful to someone: sometimes an image you like has poor pixel resolution, and even printing it on A4 paper won’t produce a clear, beautiful picture. This is where AI services for upscaling resolution come to our aid—they can literally work wonders. You can essentially create a huge image, even one suitable for a poster covering half a wall. Type “upscaler” into a search engine and give one a try. It’s free if you download it and use your computer’s resources; if you don’t want to download anything, there are paid online services where you upload the image and wait for it to be processed. I did this with a picture of Vishnu: it was a very beautiful image, but the quality was unusable.
