Chromatic aberration is just a way of life in the case of photography. In particular, the combination of high-quality gears and the user's ability to minimize the expressive purple edge. But what if a simple layer on your lens can everyone remove CA's? Enter the Harvard Technical College (SEAS) scientists who have done exactly that.
It is called "metacorrector", the coating consists of a "one-layer surface of nanostructures" from the SEAS press release.
The structures are shown in the picture below.
Structures or "nanopillas" change the speed at which light reaches the center, by reducing or eliminating the chromatic aberration:
"You can imagine light, because different packages are delivered at different speeds as it grows in nanopillas." "We have designed nanopillars so that all these packets arrive at the same time and at the same time," said Wei Ting Chen, Applied Physics Researcher at SEAS and Paper First author.
Here is another image showing photographs taken without (left) and meta corrector (right). As you can see, the difference is considerable.
I know that everyone here dies over the views of photographers, but technology has many applications – for example, high-resolution microscopes where clarity is paramount.
And though Harvard "is investigating [commercialisation] opportunities ", I think it will take some time before it filters us into plebs.
How to quickly correct the chromatic aberration in Photoshop
Chromatic aberration is the color you sometimes notice at the edges of your photos, unwanted colors. It happens because the colors of the light are at different wavelengths, which means that the camera lens weakens them a little differently. Here is a quick fix that compensates for Photoshop.
