ACR and Lens Correction

So, we're gonna open up this number two transforming distortion in Adobe CameraRoll follow-along image. So, in Adobe CameraRoll, Adobe CameraRoll comes equipped with a lot of things, as we discussed before. And if I wanted to fix this lens correction in Adobe CameraRoll, there are a couple of different tools that I can use for that. If I come over here to Lens Corrections, this gives me the option to look at not just the make, the model of the lens and maybe the lens profile from that lens, and it'll give you the opportunity to either check my remove my chromatic aberrations or enable those profile corrections. By default, if you do not have this checked, these will be grayed out, meaning it's not doing any lens correction for you at all. So, if I click Enable Profile Corrections, you'll notice that it takes the warping that's happening from barrel distortion of the lens, and it starts to push it back into the back of the image. So, let me go and turn that off so you can see that again...

. Before, after. Now, you all also notice is that we had a vignette around here. We had a vignette around here because lens is naturally vignette. Where vignettes come from, vignettes come from what happens within the lens and how the light is gathered within the lens, and we add it later for effect. Now, if we press that Lens Correction button, it's gonna analyze the profile of this lens, and it's gonna go ahead and fix that as well. But what really want you to pay attention to is not the fact that it's getting lighter or darker because that lighter or darken thing then can be like why is my image getting lighter, especially after you make all of these corrections. If you do all these corrections over here in the Basic settings, and then you see your image just get lighter, I'm like, what's going on? That's the vignetting that's happening. What it's also doing is it's trying to fix the warp in the barrel distortion within the image. And it does a pretty good job of fixing the bowing that's happening in the middle of the photograph, where we might get some bowing kind of coming up along the top of here, look along this line right here, and when I change that Enable Profile Corrections, notice how that kind of bowing that was happening, that's the barrel distortion there is now getting straight. So that helps, but you notice that we still have our perspective kind of like this, it's still like a V shape there in the back, where lines should be vertical. There are some other corrections here where if you go into the correction amount, you can change the amount of distortion that's happening there, to make it more or less distortion, and you can see how that barrel is changing at the same time, if you want. If the profile didn't select exactly what you wanted to select to fix, you can do that there. And then, the vignetting, like I said before, we can make less vignetting or get that vignetting back, based on the settings that come by default. So let's just change this back to 100, and this back to 100. Because in here, we got into a point now, we look at this image, we did our lens corrections, and we're like, well, that really didn't fix our problem. So we don't have to jump into Photoshop at this point. There's still some things in Adobe CameraRoll that we can use to fix that warping, and that's up here under the Transform tool. Under the Transform tool, you're gonna see a couple of different settings here. The Hover over is gonna tell you exactly what's gonna happen here. If you press A, it's gonna try to automatically balance to photo out for you based on what it believes horizontal and vertical lines are. If you go with this one, it's gonna apply a level correction only. If you apply this, it's gonna be level and vertical correction. And if you try this, it's gonna be level, horizontal, and vertical correction all happening at the same time. And then, this guy right here is where you get to draw guides to tell it what those vertical and horizontal lines are. So let's go ahead and break those down for a minute. If we're to press A, for the Apply balanced perspective correction, what happens here is that it does a pretty good job of aligning our image up. We've had a really nice balance here, but you see here how, as we've talked about before, once things go out the scale of the image, you start to get those transparent spots around your photograph. Well, there are some things in Adobe CameraRoll that are smart enough to fill those in. This is, unfortunately, not one of those tools, so it can't fill that stuff in for us. So if we wanted to go with this balanced setting here, we'd have to come down to where it says Scale, and Scale is gonna basically be a zoom, to zoom us in and out of this photograph. So, if I were to zoom this over, it's gonna get us further into the picture, right there, and that looks a little bit better. Then we have the offset of X and the Y. If, after we zoom in, we still wanna see more of the top or the bottom, we can change the offset by moving this up or down to get it more in line of where we want it to be. If we wanted to change the offset to the left or to the right, we have the X-axis and the Y-axis. It even shows you little arrows there for us that might not be smart with graphs. I tend to like math, so I can get the offset of X and Y. The Aspect, if we move the aspect ratio, it's gonna either make the image fatter or thinner to try and get the aspect ratio to fit within what it is you're trying to do for that balance correction. We can change that back to zero. And then, Rotation would be, maybe you wanna line up one of those lines a little bit more and get it more straight. You could rotate this image without using something like the Straighten tool. This would be a manual version of straightening. Let's go ahead and change these back. So, by default, once we click that upright, it's gonna clip us in on the sides, we'd have to zoom into this. And when we do that, though, we're losing that shadow there, which is actually kind of cool. So, if I were to click just the level, it's just gonna try and level out the bottom of the photograph, or the back of the photograph, I should say. And if we go with vertical lines, it's gonna try to make an application. It's gonna make our vertical lines more straight. So it's pretty smart with it finds those things. So you're shooting with the wide-angle lens, sometimes you shoot with that, knowing that you're gonna lose something. And if you shoot with that, knowing that you're gonna lose something, and you're okay with scaling into this image, then this is perfectly acceptable. But there are also times, if we press this button, this is just gonna try and balance all of what we see right here, your straighten, your horizon, your verticals, and any perspective correction at the same time, too. I'm just gonna press the Cancel on this. This guy right here, this one is where you can draw guides to tell Adobe CameraRoll what the straight lines are in the image. So, this is a pretty cool feature. I'm gonna press Control and Spacebar, and click to zoom in here. If I know that this is a straight line, and I click right here, and I drag up, I can press the Alt or Option key and move that over. And what Alt or Option is gonna as I move it over, notice how if I just do this, it's flying, and it's getting really hard for me to get this perfect. If I press Alt or Option, it's gonna restrict my movement to a really slow movement. I'm moving this mouse pretty crazy to the left and to the right, and it's not getting me go out of the confines, basically, of where I want to make that straight line. So, if I put that line right here at the edge of this and unclick, and then I click over here to this side, maybe click right here, and drag this up, and then Alt, oops. It's flying all over on me. Ah, I never learned to fly. It's like that up-down thing when you are flying. (chuckles) Okay, stop, calm down, you're drunk. Press Alt or Option, and then just click right over here. Stop, there you go. And then, I'll just press Control and Spacebar, Fit in View, and again, you see what it's doing there is, I'm telling it what those vertical lines are, and then, if I wanted to get even more precise with this, I can come in to another area within the photograph, say right here, and tell it what I want. A horizontal line to be, press Alt or Option. There is the horizontal line, and then pick another horizontal line from here, Alt or Option to see what I'm doing, there we go. So that would be me telling Adobe CameraRoll, hey, these are the lines that are straight. I got a straight line over here, I got one over here, I got one over here, and then it's going to go ahead and take what I've given it, and it's gonna morph the image to the way it needs to be in order to fix that perspective. But again, we still have those areas that are cropped off on the sides. As we've talked about before, we don't have to be stuck with that. We know that we can use something like the Content-Aware Fill tool 'cause we've already talked about that. We've talked about how we could fill in areas that aren't necessarily there. So what I would do is something like this at that point, is then I just press Open Image, and I can open this up in Photoshop. And if I wanted to select those areas on the outsides, I could grab the Magic Wand tool, click outside here, and it's got both of them select because the Contiguous is unchecked. If I press Shift F5, to Content-Aware Fill, it's gonna do its best to try and fill something in. Look, it even made its own sculpture here. (chuckles) Look at that, like, whoa, yeah, that can definitely, it even looks like it fits. (chuckles) and then from there, I could clean things up a little bit, use parts of pieces on the other side and fix that up. That's basically using Adobe CameraRoll to fix basic lens corrections that you'd find with a wide-angle image.
