Harvard Engineers' Lens Camera & # 39; Metacorrector & # 39; They have invented the General Annoyances Repair of a photo



Chromatic aberration is a livelier in photography. A combination of high-quality gear – especially lens – and user skills can minimize purple stripes. But what would happen to a single layer of your lens to get rid of CA? Enter a group of researchers from Harvard School of Engineering and Applied Sciences (SEAS), who have done this specifically.

He has been nominated as a "countermeasure", consisting of the "single layer of nanostructure surface" coverage, according to a press conference of the SEAS.

The structure can be seen in the figure below.

Structures, or "nanopilots", change the speed of the light when it reaches the focus point to reduce or eliminate chromatic aberration:

"You can turn on the light in different packages that are distributed at different nanomaterials that are deployed. We have designed Nano-enabled devices simultaneously and spread the focus at the same time," said Wei Ting Chen, Associate of Applied Physics Research at SEAS and the first author of paper.

Here is another picture, without taking pictures (left) and right (metacorrector). As you can see, inequality is crucial.

I know we are here more than photographer solutions, but it has a lot of technology applications, for example, in high-resolution microscopes, because lightness is very important.

And while "exploring Harvard" [commercialisation] options, "I think before we strain some time before plebs to us.


How to Quickly Fix Chromatic Aberration in Photoshop

Chromatic aberration on the edge of your photos is that sometimes the colors that you notice are unwanted distortions. Because light colors have different wavelengths, this means that the camera lens is somewhat different from the reference. Here's a quick solution to Photoshop compensation.
