- Earlier we talked about spherical projections
and cubical projections, and you might find that
you need to convert from one to another,
maybe to be delivered to a client,
maybe for post-processing.
So let me show you how to convert from
one projection type to another projection type.
In our post-processing video, we saw
one way of editing the nadir area.
Again, that's the area that usually contains a tripod.
But if working in Photoshop and taking that much time
doesn't fit into your workflow,
there are some other options.
For instance, PTGui has a way of converting
your equi-rectangular image into a cubical image.
And that's here under Tools, Convert to QTVR/Cubic.
QTVR is QuickTime Virtual Reality,
which we're not really using anymore.
Cubic is the type that we are looking for now.
So I can add a file, in this case I want to use
my image of the memorial steps that we just
tone mapped and details enhancer and
post processed with finishing touch.
So I open that one, down here in the Output section,
I want to choose Cube Faces with either
six separate files, or a strip.
So what that'll do is, as it says, give us six images
and those are the inside of the cube faces,
as if you're standing inside of a cube,
the images are actually projected
onto the inside of the cube.
So let's go ahead and use the strip this time,
so we have one image to edit only.
And we'll save to the Source Image folder, that's fine.
I like to leave Automatic if I'm using this Converter,
just so that it uses the full-size image.
Like everything else, that takes
a few moments to do the conversion.
Okay, let's go find our resulting image,
do that in the Finder.
Memorial steps,
and we're gonna see Cubic in the file name.
Let's make it a little bigger, here we go.
We see Cubic in the file name,
and that's going to show us,
make it a little bigger for ya,
that's actually six separate images
all in one strip to make up that 360.
The one we're interested in is
all the way here on the right.
So let's go ahead and open that in Photoshop
where we can do our cloning,
much like we did before in our post-processing video.
You see some advantages to this kind of projection, though.
There isn't the distortion that was happening before
where it was more warped, here you can see the lines
are much more straight, and that's going to make it
easier to do our editing.
I wanna open that in regular Photoshop, not in camera raw.
Zoom in here, just again, grab our clone stamp tool,
choose another intersection,
just use that same information.
The color's a little funny, so if we want to,
we can take some time to touch up.
Here I would recommend a Healing Brush, typically.
You can sample from here
and just kind of blend it in so it doesn't look as obvious.
Not bad for quick and dirty editing, hey?
All I have to do is save my image,
saving it as the same image and replacing it.
And now I've edited my nadir image.
You see here the logo for
a software application called Pano2VR.
I want to show the logo or icon here
because it's likely new to most people watching this video,
but it's my go-to application for converting panoramas,
and many of us panoramic photographers
consider it indispensable.
It does more than I'll show you now, but we'll go into
more depth in this application in a later video.
The first conversion we'll do in Pano2VR
is to start with our cubic strip that we just created
and edited, and we'll convert it back to equirectangular.
I'll click the input icon, and we'll choose
the cubic image that we just worked on.
It's here, click Open,
and we see an interactive preview in Pano2VR,
but all we need to do is go up here
and use this Convert Input button.
When I click the Convert Input button,
I can choose my Type, and by default
it's already equirectangular.
I can actually leave the width at the default setting
because it's using all the pixels.
Leaving it a TIFF format,
and these other items don't apply,
although we'll talk about the patches in a minute.
I'm continuing to use the default output file names,
so I don't need to change anything here,
and I just click on Convert.
As we've seen before, it takes a little bit of time
to remap the image, but in a moment, we'll see the converted
file below, where currently you can see the six images
in the shape of a cross, in a moment
we'll see the equirectangular image.
There it is.
We can also take a look to make sure that we have
our edited image by looking down below
to see that our tripod is gone.
If I go back to Bridge now, I can see that
my final image has been saved there already.
These file names are getting long, but they are descriptive.
So I have the file that I used the details enhancer,
used the finishing touch, and it's the final equi
for equirectangular, and if I zoom in on it,
I can see that it's the full image, no tripod.
