Post Crop Vignetting in Lightroom
Vignetting, I'm gonna show you some tricks with. Vignetting is the process of darkening the edges of your picture. There's two different places where you'll find it. The first is under Lens Corrections. Under Lens Corrections you're gonna find a choice down here called Lens Vignetting. And if you were to move the amount slider, you would either brighten or darken the corners of your image. This is not where I darken my image. This is designed to compensate for a lens. If a lens delivered not enough light to the corners of an image, which is not uncommon, you could bring this up to compensate until the corners look just as bright as the center. The problem with that is, if I choose to grab the crop tool, and I crop in on my image so that it's not using the original framing, instead it's using my new framing. I might wanna do that after doing basic lens corrections because I can see some curvature in this image. So I'm gonna turn on that, and I might wanna do some rotation. Let's grab ou...
r little, right here and rotate. Alright. But now, if I do vignetting underneath Lens Corrections then look at where it's going to happen. It's gonna happen based on the original framing of the image. And so it will darken up here in this corner, that corner even though its outside of my framing. Does that make sense? So instead, what we need to do is, on the right side, get away from Lens Corrections and go to Effects. And under Effects there is a choice there, and it's called Post-Crop Vignetting. Whereas pre-crop vignetting means use the original framing of the shot. And so that makes sense, I hope, why we're here. And here are the tricks I wanna show you. When you do this you can darken the edges. And I often do darken the edges because then your attention is drawn to the colorful and bright middle. I would say, with these sliders it's sometimes hard to figure out exactly where they should go because they seem to do subtle things. But if you hold down the option key, Alt in Windows, there's a hidden feature. And that is when you hold down the option key it's gonna act as if your amount slider was turned all the way as low as it can go. Which means that when I click on this I'll see much more dramatic version of what I'm getting. And it makes it easier to judge what setting I might wanna use. And that works for all the sliders that are below amount. But it's not readily apparent that that's the case unless somebody tells you about it. And then I might finally adjust my amount. Let's decide exactly how dark. When you do that be careful though. If you have any bright areas near the corners of your picture it's gonna look artificial. As you are darkening up those corners in, if there was that much light coming through, it shouldn't darken that up. So there is a slider here called "Highlights", and it means if there are any bright areas near those corners keep 'em bright. You bring this up to determine how much are you gonna do that. So watch the bright areas above his head as I bring this up. You see the highlights getting brighter again. So I can decide exactly how bright does that need to be to make it look natural. And so post-crop vignetting is one of the things that I like to do to help get the focus on my image, being towards the middle. And what I would say is, the more complex the image is, the more I can get away with vignetting. The simpler the image is the more obvious vignetting is. If I just have a blue sky, some ocean at the bottom, and that's the picture. If I vignette it it'll be so obvious that I'm vignetting it because there's no detail to compete with the vignetting. But if it's an overly busy and detailed image, like one of those street market scenes, you can darken the corners a lot and nobody's gonna notice because there's so much other detail going on in that scene that it's hard to tell that there's that slight darkening on the edge. So just be a little bit conscience of what kind of image you're applying it to.
