- [Instructor] In the last movie,
we changed some of the external editing preferences,
in Lightroom Classic.
And we talked about how that would affect files
that are passed from Lightroom Classic in the photo shop,
and the files that come back from photo shop
in the Lightroom Classic.
So here are the custom settings that we chose,
file format PSD, color space sRGB,
bit depths 8 bits per channel, or per component,
and those settings are particularly useful
if you mostly prepare photos for use online.
And then we also came down,
and left stack with original, checked.
And we changed the default file naming template,
so that it now says, "edited by JFK."
So now let's see how that looks in practice.
Here in Lightroom Classic, I have a raw file.
And I'm going to take that into photo shop.
As we did throughout the course,
I chose photo, edit in, edit in adobe photo shop.
And the photo opens in photo shop,
and if you noticed the document tab,
says that this is still a DNG file, or raw file.
But photo shop can't really display raw files,
so actually under the hood,
as soon as this photo was was passed to photo shop,
it was rendered from a raw file, into a pixel based file.
But we don't see that in the document tab until we save it.
Now let's take a look at some of the information
down at the bottom of the document window.
I'm going to press and hold,
the arrow to the right of that information field,
and I'm going to choose "document profile."
And now we can see,
that the profile associated with this file, is sRGB,
and that the bit depth is 8 bits per channel.
And that's because of the way that we customized,
the external editing preferences.
Until I change those,
all of my files will be rendered with those same properties.
So I'll make a change here,
I'm going to go and add a hue saturation adjustment layer,
and I'm just going to increase the saturation a bit.
And then I'll go to the file menu, and I'll choose save.
Now let's go back to Lightroom,
and here you can see thumbnails of two images,
in the same folder.
I'll make those bigger so you can see them better.
The one that's selected,
is the one that we just saved from photo shop.
And as you can see, this is a PSD file,
because in the external editing preferences,
I switched from the default of TIFF, to PSD,
for files that are going through the roundtrip workflow.
And you can see that the file naming convention
is changed too, now it says, "edited by JFK."
Also, stemming from my customized
external editing preferences.
And then over on the right,
we just have the original DNG file.
And if you remember,
we left the preference for stacking, checked.
These two files are now together, in one stack.
And you can barely see that if you look over here,
there are couple of lines in the left,
and a couple of lines on the right.
If I right click on those lines, and I choose stacking,
you can see some of the things
that I can do with this stack.
I could un-group these, from this stack,
I could remove one of the photos from the stack,
I could split the stack into multiples,
I could collapse it, expand it, and so fourth.
And this is particularly helpful,
when you're looking for a file,
and for the related image,
that came back through the workflow.
And especially when you're looking at a lot of photos,
for example, in this sort of a view.
Now those two photos are right next to one another
in a stack, and I can collapse that, and make it smaller,
or expand it, and make it larger.
So that's how your external editing preferences
in Lightroom Classic affect files generated
during the Lightroom photo shop workflow.
