Fringing and lens profiles

“

- [Instructor] Let's take a look at another image. In this case, I see that a built-in lens profile was applied. Some lenses have lens profiles automatically attached to the camera itself. In this case, I see that the Sony camera recognized the Sony brand lens, and it read the profile. This is more common in mirrorless cameras than it is in DSLRs, but it does help, and I see that the raw file had a built-in profile to clean up the chromatic aberration. Now, this is useful, and you really can't disable this. It's going to be applied because the manufacturer recommends it. But we can still enable lens correction, and in this case, you see a huge fix. Look at the line here that's bowing along the edges. Now, when we apply that, we get a straight edge, which is quite useful. If it's not exactly right, we can also apply additional distortion correction and you see that it continues to stretch the image. In this case, I'm going to do just a little bit of that to clean up that edge, and what I'm looking for are some of these lines. Because the camera was a little bit closer to the subject, the distortion was emphasized a bit more. The vignetting is the lightening or darkening at the edges, not a traditional vignette that you apply as an effect, but more actually caused by the lens itself. So if you're seeing unwanted dark or light pixels, this can brighten or darken those edges. And that worked quite nicely. This shot shouldn't need chromatic aberration, because it was already applied, but let's go ahead and apply an auto-adjustment for exposure. That definitely helped, and I'm going to back down the global exposure a little bit with more of a lift to shadows and let's take a look at the color itself. We'll do a custom white balance here. And that definitely helped. I'll just back that off slightly. And now, we've got nice sunlight with more accurate color in the scene and a definite change to the lens. Notice all of that distortion is pulled out and it looks tremendously more natural.
