Optics
the optics panel is an important panel that you'll use occasionally. And sometimes people actually just leave it on all the time. They just turn it on every image. Um but it serves a very specific purpose. So let's look at this photo of this old rundown shed and I want you to see that when I zoom into it and I'm zooming in quite a bit. You can see that in the areas where there is a lot of contrast between something really bright and something really dark. There ends up these fringes, see that red and that green. Those can be taken care of in the optics panel by just removing the chromatic aberration. So if I click on that check box, do you see how it just neutralized those? It got rid of that red and green and it also got rid of some other areas up here. So pretty much it took care of everything and most of the time it's going to take care of those issues which usually show up on the edge of someone's black jacket or they show up at the edge of like a mountain, you can see it happening...
here on this mountain as well as we zoom in way close, you can see it happening right there and it's because this is really bright and this is really dark and so it just shows up on edges like that and so we can remove that chromatic aberration just by clicking on that little check box and it is gone magically. However, there are some times when that won't work, it'll clean up most of it, but there will be another fringe that shows up or they'll that fringe is still too big. And so when that happens, I'm gonna take you to another image here. Let's see. I'm gonna go to this image, let me zoom in really close on these leaves and you can see there's a fringe right here, that's kind of a magenta. And and I think this will actually be taken care of by the remove chromatic aberration option as well. Yeah, it is. But let's pretend it wasn't. If it didn't get taken care of you can go to the d fringe option and open that panel up and when you open it up, you can either choose the purple magenta range or the green range and when you do that, you're going to choose, what am I trying to clean up? I'm trying to clean up that magenta. And so I'm going to click on this little color dropper. When I click on it, I simply go over and find that particular color and make sure that it's centered on that color. And when I click on it, it's going to remove it. But the beauty is see how it's still there. A little bit. The beauty of this is that I can be a little bit more strategic about it. So I've chosen the general color and it created a general color, but I can expand that color and say, well I want you to bleed a little bit further out from that purple and see how now it's gone and I can also choose the amount of removal that's going to happen. And so I can really go overboard or I can do it under board. So I'm just going until I remove that completely. So it gives you more control over those items. I can also go to the green and I can look for there's a bit of a green fringe but see it couldn't find that green fringe. It was a little bit too small, a green fringe and quite frankly, I'm afraid that if I, if I click on this green fringe there, well that's pretty impressive. So it sees the green leaves but it sees the green fringes separate. And so I've just removed the green fringe, which I can then expand a little bit more on that green fringe and remove a little bit more of the green fringe. And it's kind of getting rid of that one on this side of that stem. So now I just back off. So let's just let's put this color dropper away zoom back out and now all of those green and magenta fringes have disappeared. So you have the ability to do it by automated. So remove chromatic aberration, just automates all of it. Or you can go in and different very specific areas. The other thing that you can do in the optics area is simply enable the lens correction and when you do that it actually changes not only the the bowing of the lens so every lens has a slight bow to it, especially wider lenses but it also takes out the natural vignette NG. And so you see that happening here where see how it's really dark on the edges of this photograph. But it's just the natural vignette NG of the lens. And as I enable that lens correction, it brightens up the area so if you see your image is quite dark especially around the edges, just go in here and click on that enable lens correction. And when you do that it will remove that natural vignette Ng and it'll remove the natural Boeing of that lens. The beauty is that you have this toggle to drop it down and you can actually choose to maintain the distortion. But remove the lens vignette or you could keep the distortion so I want these lines to be straight So I want the distortion to be removed. But I don't want the vignette ng to be removed so I can take the vignette ng down. So now I have the best of both worlds. I got rid of the Boeing but I kept the vignette ng or I can go like 50%. So I'm brightening it up just a little bit and I think I like that better. So that's a really good way to solve problems like Boeing of lenses vignette NG things of that nature and don't just think of it as a problem solving tool. Think of it as a way of increasing decreasing artistic effects.

Thoroughly enjoyed your class, have learned so much about how take my Ipad to another level, now can't wait to put it all into practise!

Sometimes it's hard to know what the instructor is pointing to so it's easy to get confused. Better job is needed in explaining what you are pointing to.
