- [Instructor] We all have photos like this one
that came out more crooked than we intended.
The transform panel is where you go
to correct distorted perspective
like we see here in this photo of a staircase with columns.
Lightroom's transform tools,
are also referred to as upright perspective correction.
You'll find this photo in our Chapter 7 > 07_06
I have the transform panel here, open in the develop module.
Let's take a look at the options here.
At the top we have a bunch of buttons.
These buttons offer different automatic options
to correct the perspective.
Sometimes one of them will work perfectly
to fix an image.
So I usually try all of them.
If we click on Level, it's going to attempt
to level out those stairs.
And if we click on Vertical, it's going to attempt
to straighten out the columns.
Full, we'll do a combination of both of those.
And it's really similar to Auto.
I'm going to reset this and take a look at these sliders
that are below here.
These are ways to manually try
and correct the correction.
So for example, we'll take the vertical slider
and we'll move it to the left and using
that grid overlay and see it stretching those columns out.
And I'm trying to find a place
where they look more straight.
And when you use one of these sliders, you'll need to turn
on the constraint crop,
because what happens is we get these white areas
on the side as the image gets tilted.
So I'll click that and we'll see that crops it away.
It didn't do a very good job though.
So I'm going to reset it.
I want to show you the guided upright,
because that's my favorite and it's going
to give you the most control.
So we have the button
guided here and we have an icon here and they do exactly
the same thing.
If I click on the icon, it picked the button.
Now with the guided ,you lay down guides
on what is supposed to be straight.
So I'll come over to the left edge
of the top stair here and using
that loop view,
which is like a zoomed in view with a cursor
in the middle.
I can place the guide.
I'll start it by clicking on that end,
right at the top of the stairs.
And then I'll drag over to this side
and using my loop view,
I'll make sure the cursor is right on the top of the stairs.
So this is telling light room, make that level.
Nothing happened yet,
because the guided upright requires two guides
and we only have one.
So let's add one to the left edge.
I'll put it right along the left edge of this column.
And that's starting to straighten
this out a lot,
but now the right edge is still leaning in.
So let's come over and add another guide
and we'll pull this down and line it up
with the edge of that wall.
And now the vertical lines are perfectly squared up
and they look great.
Overall, the image is looking pretty fantastic,
but if we look really close,
notice that the bottom of the stairs
are kind of running downhill.
So let's add one guide down here.
So I'll align this to the top of the stair,
pull this out,
align it on this end,
and then remove as soon as I take my finger
off the mouse button, it applies that guide
and now our images perfectly squared up.
It's amazing how well this works.
I want to show you a couple
of the options down here in the tool bar too.
Notice that the show loop is turned on and that's extremely
helpful to get the exact precise location
of your guide.
So you'll want to turn that on.
And then if you hover over
the show grid here, it'll show a grid overlay.
And that's a really helpful way to check
and make sure that what you've done
has actually straightened the image out.
You could always come back to these guides and click
on them and move them around
to restrain it out.
But I'm pretty happy with this so I'll leave it.
When you're done and you're happy with how it looks,
you can click the done or hit the enter key
to apply that.
Try the upright perspective correction
and the transform panel
on your cricket, architectural images,
you know you have some.
I bet you'll be amazed at how much better they'll look
with a little straightening up.
