Join Richard Harrington for an in-depth discussion in this video Lens issues: Distortion, part of Learning Tiffen Dfx.
- Besides things like chromatic aberration,…or control over depth to field,…many lenses introduce artifacts or distortion…based on the style of lens.…This is particularly true with…wide angle footage, and Tiffen has…a wide range of corrections…for wide angle distortion.…Let's bring in a couple of shots.…We'll start here with a GoPro clip.…In this case, Tiffen has two filters…that really come in handy.…
From my filter browser here…I'll go to the lens category,…and start with the lens distortion filter.…This one makes it really easy to adjust curvature.…Let's twirl these down so there's…some sliders that are easy to access,…and bump up the distortion amount.…Look at how I can unwrap that image.…
Either emphasizing the wide angle,…or bending it the other way,…so those lines actually start to go straight.…Using the curvature slider,…you can really push that even further.…Now, this has gone too far,…but you see how it's bending the image along the y-axis.…I'll take that back closer to the middle,…but those two values working together…
