Adobe Photoshop has a new AI feature that can quadruple the pixel count in your photos.
The tool, called Super Resolution, is now available in Camera Raw 13.2 and will soon be available in Lightroom and Lightroom Classic.
The feature uses a machine learning model trained on millions of photos to enlarge the images while preserving their sharp edges and fine details.
Programmer Eric Chan said it was very easy to use:
Press a button and watch your 10 megapixel photo transform into a 40 megapixel photo. It’s kind of like how Mario eats a mushroom and suddenly spreads in Super Mario, but without the nifty sound effects.

This feature could breathe new life into photos taken with older cameras.
While this is usually not as convenient for modern high-resolution cameras, it could still prove useful for certain tasks, like working with well-cropped images.
Adobe developed the functionality by training the model on millions of pairs of low and high resolution image fixes.
These patches are cultures of detailed regions of real photos, such as flowers and fabrics. When the model receives enough examples of different subjects, it learns to scale low-resolution images while retaining detail.
To use super resolution in Photoshop, right click on a photo and select “Enhance …” from the context menu.
The system will then spit out an enhanced negative digital file (DNG) which can be edited like any other image.
While super resolution works best on raw files straight from a camera, it can improve other formats as well, such as JPEGs, PNGs, and GIFs.
Functionality is currently limited to images below 500 megapixels, but that should be more than enough for anything but huge panoramas.
