Selfies are everywhere, but they change the way we perceive our own faces. There are a few reasons that happens.

In a recent study, researchers have developed a compound metalens that enables distortion-free imaging. The study, published ...

(b) A compound metalens effectively eliminates the barrel distortion. (c, d) Ray-tracing modeling of the (c) singlet and (d) compound metalens. The light incident angles (in air) vary between 0 ...

(a) A singlet metalens suffers from large barrel distortion. (b) A compound metalens effectively eliminates the barrel distortion. (c, d) Ray-tracing modeling of the (c) singlet and (d) compound ...

Plan on using external lighting for any macro shots with the Lumix LX3. JPEG: Barrel distortion at 24mm is 0.6% JPEG: Barrel distortion at 60mm is 0.1% JPEG: The Panasonic LX3's 0.6% barrel ...

It showed average amounts of barrel and pincushion distortion (not bad for a long-ratio zoom lens), but much better than average corner sharpness and chromatic aberration than we normally find in ...

Theia’s patented Linear Optical Technology® lenses provide an ultra-wide field of view, correcting barrel distortion optically, without the use of software. Theia’s compact, 5mpx and 4K resolution ...

The super-wide, super-fast and super-distorted 7Artisans 10mm f/2.8 II ultra-wide prime is equally brilliant for astro and creative photography – and if that wasn't enough, it glows in the dark!

In a recent study, researchers have developed a compound metalens that enables distortion-free imaging. The study, published in Engineering, presents ...
