Superfish Distortion Correction
One of our newest features is the ability to apply Distortion Correction to photos captured with the Superfish lens. Before diving in to learn how to use this feature, let's go over what this feature is all about.
If you've used our Superfish Lens before, you've probably noticed that "fish-eye" or "barrel" effect in your images, with lines being curved towards the edges. In basic terms, lens distortion is when a lens sees curvy lines when there should be straight lines.
While different types of lenses have different amounts and types of distortion, generally you get more distortion the wider a lens is. This happens because the lens is trying to squeeze a really wide field of view onto a sensor that doesn't quite match that size. With wide lenses, you get what is called Barrel Distortion where the lines curve outwards.
Examples of distortion with the Superfish Lens:
Is Lens Distortion bad?
Straight lines appearing as curved lines through the lens isn't necessarily a bad thing. In fact, the photographers who took those images above chose to leave the lines curved. It creates a distinct and unique feel that the images wouldn't have without the distortion. Some people may say that using the Superfish Lens for portraits is a no-no because it distorts a person's face or body -- again, there is no right or wrong answer this because art and creativity is limitless! You should experiment with and see what suits your personal taste.
If you find that you'd prefer to have minimal distortion in your images, you can apply Distortion Correction.
What is Distortion Correction?
Distortion Correction is an adjustment that alters the pixels of the image to straighten out lines and reduce the "fish-eye" or "barrel" effect in the image. In basic terms, you can say that it is flattening out the image to have less of a dynamic effect. Usually you would do something like this after capturing your image in a photo editor such as Lightroom. Don't worry about having to do that anymore, since we've decided to bring Distortion Correction for the Moment Superfish Lens to the Moment app!
