Enlarge your old photos with open-source artificial intelligence Upscayl

I have always been interested in photography since I was a kid with my dad's Kodak 620 camera. I use it to photograph the flora and fauna in our neighborhood. My love for photography led me to purchase an Instamatic camera in high school and eventually in the late 1990s a digital camera which was just entering the market. Early digital cameras were portable, capable of quickly capturing images and easily sharing them over the Internet. But they are inferior in quality and sophistication to the best film photography. Of course, digital cameras have improved a lot since then. But my digital photos from all these years look a little, well, smaller on modern devices. Until recently, my go-to tool for enhancing digital images has been

GIMP

. A few years ago I experimented with using GIMP to enlarge a "small" image my father took in the mid-1940s. But despite zooming in, the photo lacked the detail, depth, and clarity I wanted. Everything has changed since I learned about

Upscayl

. This is a free and open source program that uses Open Source Artificial Intelligenceopen source artificial intelligenceUpscayl

After installation, you can use it to enlarge images. The GUI software is very easy to use. This software makes old photos look like they were taken yesterday, and the image resolution is much higher than the original image. In addition, you can also increase the size of the entire folder and photo album at the same time.

The left panel of Upscayl provides clear guidance on the 4 steps required to upscale an image.

Launch the software and click "Select Image" button. Find the image or image folder you want to enlarge.

After loading the image, select the type of enlargement you want to try. The default is Real-ESRGAN, which is a good starting point. There are six options to choose from, including digital art options:

It’s time to try Upscayl for your images

Upscayl is one of my favorite enlargement apps. Its operation depends heavily on your GPU, so it may not run on older computers or computers with particularly poor graphics cards. But there’s no harm in giving it a try. So download and try it out. I think you'll be impressed with the results.
