The New CS6 Feature I’ll Never Use

Photoshop, Tools Apr 20 , Episode 281

Adaptive Wide Angle Filter

This tool is basically meant to correct lens distortion issues on photos shot with a wide angle lens. In this episode I’ll show you how its meant to be used with horizontal and vertical reference lines. I spent about an hour today trying to figure out how to apply this tool in a way that would help my image, and in the end it didn’t do much at all. It did, however, work with a fisheye photo but usually the reason people shoot with those is for the bowed effect.

0:30- Why it didn’t work for me
1:45- Using it with a photo shot at 16mm
2:35- Starting with straight lines
5:00- Explaining why it doesn’t look as good as the original
6:30- Fisheye photo
9:00- Let me know if you have had any success with this tool!

This is probably better used in architectural photography where photographers will often use a tilt-shift lens to keep the vertical lines vertical whilst framing the right elements.

Could it be used to fix distortion from a panorama?

Tried out a bunch of photos with a wide angel distortion. The only one where it performed perfectly was in a landscape to straighten out the horizon, which was bending slightly upward at the sides. Looks to be the perfect tool for landscape photographers.

I have seen till 4:44 so if there is anything deny my comments in the late half please let me know.

In the video, the tool is somehow misused. First, you don’t have to make a constraint “vertical” or “horizontal” exactly. You are allowed to make them in “arbitrary” orientation. Your photo is shot with the lens pointing upward very much, so make too many exact vertical constraints will make the result wired, that’s true. That’s not the problem of constraints, that the problem of applying exact “vertical” constraints on a photo shot that way.

Second, you put three vertical constraints on the ceiling. That’s pointless because there is no obvious straight lines on the ceiling. The whole point of the tool is to put as less constraints as possible. Especially you don’t put constraints on the places where there is no obvious straight lines, or you lose the “adaptive” nature of the tool.
