Adding a darkening vignette effect

Now that we know quite a bit about the Lens Corrections Panel, I want to dig even deeper. I want to focus in on how we can work with a jpg file and also how we can add an Effect to this picture. Because so far, we've looked at how we can correct our photographs, but let's say that what we want to do here is we want to darken up the edges. All right let's start off in the Profile Tab and in the Profile tab if we click on Enable Lens Profile Corrections, we notice that Camera Raw can't figure out how this image was captured, that's because this is a jpg file and the Metadata isn't embedded in this particular jpg.

So if ever you encounter this with your files, just go ahead and select this pull down menu here and try to make a choice. As you do that you can see that it will try to figure things out. In this case it did a great job, it figured out that I used this 70 to 200 mm lens, and here we can see our before and after. Alright, well, now that we seen how we can make Custom Selections from our Lens Profile menus, let's go to the Manual Tab. Here underneath the Manual tab what I want to do is darken those edges. So I'll click and drag this to left, and I'll also click and drag my midpoint slider to left.

And so now I have this darkening effect. Here is my overall before, and now my after. And really in this brief movie, I just wanted to highlight how we can use these controls to correct our images and also to apply Effects, like this Lens Vignetting Effect, which we've applied to our photograph here.
