In this lesson I'm going to show you how to use this lens corrections tab.
I'm using Photoshop five dot air w the practice file if you want to follow along so if you go to this
tab you'll have two options down here profile or manual under profile you get sort of an automated way
to fix a lens quote unquote fix because what it's doing is it's going to try to remove any warp in veneer
adding that might come naturally from the lens you use.
Typically if you're using a wider lens then you'll have more of a warp around the edges which we were
using for this photo right here.
The Sony 16 to 35 all the way on 16 millimeters so it was very wide on the full frame camera.
So first if we'd check enabled profile corrections look what happens.
This is the before and then after it becomes a little bit brighter around the edges and then it feels
a little bit like it might be warped.
But what's happening is it's actually UN warping it to make everything look a little bit more natural
as if you were actually there you'll notice that Photoshop already knows what camera what model lens
and what profile we were using.
And this is all automated and it's built into the metadata of this camera.
If you don't have a smart camera if you're using a manual camera or an old camera or a lens that doesn't
match with the camera itself in terms of manual camera I meant and meant like an old lens or something.
You might not have this information so you can go in and actually find the specific lens and model that
you are using and it will adjust accordingly.
You can also manually adjust a little bit more or less with this distortion and vignette ing options.
So dragging the vignette left to right will increase or decrease the sort of vignette fix that it has
applied.
Say you want to get rid of the door Stalin but you still like the bin yet we can add back the vignette
that the lens naturally has the distortion on the other hand will again bring you back to how it was
shot to how it was a fixed in the middle or if you drag to the right it will sort of flatten it out
as even more so you can adjust this to your liking.
Now these corrections are only if you don't like the look of your lens if you like the look of your
lens then there's no real reason to adjust these things.
Now what about chromatic aberration.
I don't know if I'll be all to see it in this image but sometimes depending on the setting and situation
you can kind of see it right here.
You'll get these sort of purple and green lines on the edges of things checking on Remove Chromatic
aberration we'll get rid of those lines and make it more of the natural color which you can see here.
If I turn it on and off it makes this line more blue which is probably what it more naturally look like.
This photo has a lot of blue.
I'm not seeing really much green or purple.
If we turn this off.
So this is a good example of a lens and a camera that doesn't shoot with a lot of chromatic aberration.
But I just wanted to point that out.
If you are in a setting where you are looking at your camera and you see like some weird purple hazy
lines on the edges of things or green that's what chromatic aberration is.
And by checking this on or off you can sort of remove that.
Now the manual tab right here basically allows us to do what is done here on our own.
So let me go down here say fit to view so we can see our whole image which is important when doing these
types of corrections.
And so here we can basically do whatever we want.
We can make it bulge which actually gives it an interesting effect if you want that or stretch it the
opposite way.
If you do stretch it like this you'll want to go in and crop so that you don't see these edges.
And if you see this sort of grid behind your photo that means the background is going to be transparent
so you don't want to see that when you're saving your file so you would want to crop in if you do that
sort of distortion and then same with the D fringe if you have a specific color.
So let's zoom in here really quick.
So this has that sort of purple fringe fringe on this line.
This is the chromatic aberration that if we increase the purple amount and then adjusts or the hue angle
you can choose more or less it will get rid of that.
So see if I go to before or after.
See how it got rid of that sort of purple line.
This allows you to pinpoint either a specific green or purple to get rid of in terms of the fringing
which is what that chromatic aberration is.
Let's zoom out one more time.
And lastly you have been getting.
So this is sort of a way to decrease the vignette and also choose a midpoint which is happening for
the entire image itself.
It's not like this effects that we added before which is a post crop in the adding this is just fixing
the entire image when you're zoomed out and on cropped doing what is happening here in the profile but
in a manual way cool so this is the lens corrections tab another sort of advanced feature not one I
necessarily play around with too much because typically I like the way my lenses look.
Sometimes when I shoot on a very wide lens though you do get some of that distortion around the edges
that I don't like and using this enabled profile corrections button tends to help with that.
If you have any questions let me know.
Otherwise we'll see you in another lesson.
