Every time a new lens is announced, the optical makeup is always listed. This many elements in that many groups and a certain amount of them are “aspherical”. But what exactly does that mean? Is it just nonsensical jargon that doesn’t actually mean anything? Well, in this video from Michael the Maven, you’ll find out exactly what they are, how they do what they do and why they’re a big deal.
Action cameras have become part of many a filmmaker and photographer arsenal. Even if they’re not our primary camera, they’re great for grabbing behind the scenes clips or putting in higher risk situations. And then, sometimes, they are the primary camera, capturing the action. But most of them come with a pretty severe fisheye effect.
Some can deal with this natively in-camera, but often you get the best results in post. But how can you deal with it effectively? In this super short 20 second video from YouTuber Aidin Robbins, we see just how easy it is to fix. Aidin uses Hitfilm Express for this video, but the principle is the same in other editing applications.
Remember the animation showing how focal length impacts the portrait? When you shoot with different focal lengths and your subject takes the same space in the frame, you’ll get a certain amount of distortion. As a matter of fact, this is one of the reasons why camera “adds ten pounds”. In this video, Koldunov Brothers demonstrate how geometry of the face and body depends on the distance from the camera. So, what is it that looks so strange when shooting up close with a wide angle lens?
Wide angle lenses let you pack a lot of action into the frame, but they also present a problem: distortion. Fortunately, if you know what to expect and some of the different ways you can work with it, distortion isn’t a deal breaker. In the quick video clip below, John Greengo shares some examples of the way distortion affects photographs at different focal lengths. He also shares some advice on how to you can work with distortion and use it to your advantage.
