Luminar 4 is only days from being released, and Skylum is gradually revealing the AI-powered features it’s going to offer. After automatic sky replacement and smart background enhancement, Skylum is now showing off the automatic Skin Enhancer & Portrait Enhancer. They’re made to assist your retouching process and make it faster than ever before.
What I like about Photoshop is that there often several ways to get the result you want. Nathaniel Dodson of Tutvid shares some of his favorite techniques for performing different kinds of enhancements, from converting photos to black and white to cleaning up skin. In this video, you’ll see plenty of useful and quick techniques to add to your bag of tricks.
We’ve seen some of the algorithms that can enhance low-quality photos. The researchers from Oxford University and the Skolkovo Institute of Science and Technology in Moscow have developed a new approach for restoring damaged or low-quality images. Instead of training the neural network with thousands of photos, their system called Deep Image Prior works everything out from the original image. And without any previous learning, it turns a pixelated or damaged photo into a hi-res one.
The scientists of Max Planck Institute for Intelligent Systems in Germany have developed a new algorithm. It enhances low-res images so that they miraculously become hi-res and sharp. It only needs a single low-resolution input, and it will increase its resolution while retaining the realistic textures and details.
Even the magical light of the golden hour requires some enhancement in post-processing. There are a few ways to do it, and Denny Tang of Denny’s Tips suggest one of the simplest I’ve seen so far. He uses a single adjustment layer, and it’s the Channel Mixer. The whole editing process is pretty fast, yet gives natural-looking results on the photos taken during sunset (or sunrise).
RAISR stands for Rapid and Accurate Image Super-Resolution. It’s Google’s prototype software which utilises machine learning to provide better quality upsampling of low resolution images. They first showed off the technology in November last year, but now Google have announced that RAISR has been implemented into Google+ for Android.
The point of the technology is to save bandwidth. Many mobile users have fairly limited bandwidth. Either they have low limits, or it’s just slow. Google see RAISR as an option to save bandwidth. The idea is to scale down the images before sending out. This means they’re smaller and easier to send. Then RAISR blows them back up to their original size on the receiving end. And it wants to do this with the minimal of impacts on quality.
