- [Instructor] The lens corrections panel
is where you find camera lens profiles
and an option to remove chromatic aberration.
I'm viewing the Chapter seven 07_05 folder
And I have the lens corrections panel already open
in the develop module.
Lightroom includes numerous lens profiles.
By checking the Enable Profile Corrections,
it should find the correct lens profile for the image.
It does this by reading the image metadata,
and we can see here in the lens profile
that it found the make, model, and profile for this photo.
If I turn this on and off,
we can get a before and after of what this is doing.
The profile corrects for barrel
and pin cushion geometric distortions,
and most lens profiles also correct for vignette.
We see a little bit of vignette removed in this image.
The amount of change you see will depend on the camera lens.
There's also the option here to remove chromatic aberration
and I always turn this on,
but before I do, let's zoom in
so that I can explain to you what it is.
I'm going to click in the upper left corner
where this window is.
There's some chromatic aberration around this window.
Let's zoom in a lot further so that we can really see it.
Now we should be able to see some purple colors
on the right and some green colors on the left,
and that is the chromatic aberration.
Sometimes it's referred to as color fringing.
Chromatic aberration happens when the wavelengths
or colors of light are bent by the lens
causing a type of misregistration.
You'll notice it most around hard edges in an image,
especially high contrast areas
that are captured with a lot of backlight.
And this image isn't particularly high contrast,
but we do see some chromatic aberration
and see how easy this will be removed
just by turning this on.
So I'll do an on and off and you'll see how much better
that image is improved by turning this on.
I apply lens correction and remove the chromatic aberration
to all of my photos
because I have never found any harm in doing so.
So get in the habit of applying them to your images too.
