Using lens correction profiles in Adobe Photoshop

“

- Lens distortion comes into play particularly with wider angle lenses, but there are lots of other things that can pop up as well. Compensating for optics issues is pretty easy, but each tool takes a different approach. Let's start with Adobe Photoshop, which may seem surprising, but has a huge catalog of lenses. Once you open up a video file in Photoshop, you can bring up the timeline if you'd like so you can easily scrub through it to see the footage. Before you apply a filter, you need to right-click on the clip and convert it to a smart object, this allows filters to be applied to the entire clip. Now choose Filter, Lens Correction, you'll find in the popup list the ability to choose the camera that you shot with as well as the select the lens. Let's go here to Nikon Corporation, and you can choose the model of the camera and see different lenses that are supported by that camera, in this case, I was shooting on a longer lens, a 70 to 300 millimeter. So the correction is pretty minimal for that particular lens, but depending upon what you were shooting with, you can see different presets here to help compensate, and when you click OK, it's going to apply, and you can simply export this out using the Export command as a new video clip, but where this really comes in handy is that there are advanced options. Let's go ahead here and convert this to a smart object, and I will apply lens correction first, and this was shot on a Nikon, and I was shooting with a wider angle lens, so 24 millimeter zoom, and you see that that helps compensate for the lens issue. Now while we're at it, we can also apply camera raw as a filter, and this offers really cool controls under the Transform tab. I can click and draw straight lines on my image, and once I've placed two straight lines, it will go through and fix the overall image. You can also look for a strong vertical line, for example, I'll use this tabletop surface here and it will fix that issue of leveling the table and the ground plane, and I see this little area up here on the roof, same thing, and now the perspective has been corrected. Automatic, manual, and this allows you to compensate for not just lens issues, but also potentially any other distortion. And if you're really getting fancy, you can take a look at the Adaptive Wide Angle command, which will allow you to find curved lines caused by the footage or the lens and start to drag those lines there to snap things into perspective. Notice I can go here on the plane, and I can slightly pull those in, as needed, to better define the surface, and you can rotate those like so to compensate and fix any lines. Now if you do a lot of rotation here, you might need to scale the clip up slightly, but all of those tools working together allow for some truly amazing things, and with a double-click here, you can go right back in and continue to modify it. So I'm going to click right here along the building, and just tweak that slightly, there we go, and click OK, and we've now compensated for a wide range of issues within the shot. When you're all done, just choose File Export, and you can render out the new video.
