- [Instructor] Throughout this course
we've been using the default settings
for the edit in command
to pass photos from Lightroom Classic to Photoshop,
and back to Lightroom Classic.
In this chapter
you'll learn how to change the default settings
for the kind of file that you get back in Lightroom Classic
after it's been handled by both programs.
For example, you can choose to change the format
of that file to PSD rather than TIFF.
Or to change the naming convention for that file.
All of that
is done in Lightroom Classic's external editing preferences.
To see those on a Mac, go to Lightroom Classic
and choose preferences.
On Windows, go to edit and preferences.
In the preferences window, click external editing.
The section at the top of this tab,
the one titled edit in Adobe Photoshop
is where you'll make changes to the settings
for the file that you get at the end of a roundtrip workflow
from Lightroom to Photoshop.
At the top you'll see edit in,
followed by the name of the latest version
of Photoshop on your computer,
which Lightroom Classic automatically detects for you.
Now, a little background about what these fields do.
Keep in mind that although Lightroom is a RAW editor,
which means it can handle and display RAW files,
Photoshop cannot, because Photoshop is a pixel editor.
So when a RAW file is passed from Lightroom to Photoshop,
behind the scenes it's rendered from a RAW file
to a pixel based file
with qualities like those you see here.
File format, color space, bit depth and so on.
And the same is true when you pass a non RAW file,
like a JPEG from Lightroom to Photoshop,
when you use the edit a copy
with Lightroom adjustments option.
In both cases, when you're working with a RAW file,
or when you pass a non RAW file to Photoshop
using edit a copy with Lightroom adjustments,
the file is rendered and opened in Photoshop
as file format TIFF, with color space ProPhoto RGB,
bit depth 16 bits,
resolution 240 pixels per inch,
and compression ZIP.
So when you save from Photoshop,
the file you get back in Lightroom Classic
has those settings in it.
Now what if you don't want the format of the file
that you get back in Lightroom Classic to be a TIFF?
In that case, go to the file format field here,
and change it to PSD.
And yes, those are your only two options.
PSD, which is the native Photoshop file,
or the very similar TIFF file.
Both of these formats will retain layers
and other proprietary Photoshop features.
And both can be saved in either eight bits or 16 bits.
So if you want a smaller file,
you can change this to eight bits.
If you want a file with more quality,
leave it at 16 bits.
The main different between PSD and TIFF by the way,
is that TIFF is not a proprietary Adobe format.
So if you need to pass files off to another person
who is not an Adobe user,
then TIFF may be a safer bet for you.
The next option, color space, describes the color tag
that will be embedded in the image.
You can choose from only the ones that you see here.
ProPhoto RGB, Adobe RGB, Display P3,
and sRBG.
ProPhoto RGB and Adobe RGB are both good choices
for photos that are headed for print,
but if you mostly prepare files for online viewing
or for email, then sRGB is the best choice here.
Bit depth is the amount of information in the file.
And I usually leave this set to 16 bits,
so that I have the greatest number of tones in the image,
and therefor the largest editing headroom in Photoshop.
But if I'm preparing files for just online viewing
or for email, and I want the files to be smaller,
again, I can change this from 16 bits to eight bits.
When you're preparing an image for print
then the resolution is important.
And between 240 to 300
is an adequate number of pixels per inch
for photos destined for an inkjet printer,
like the kind you might have at home.
If you mostly prepare photos for use online,
then the resolution really doesn't matter,
because resolution has to do with
number of pixels per printed inch.
If you're not printing, then as I said,
the resolution isn't critical.
And finally, when file format was set to TIFF,
we saw that there was a compression menu here.
And I'll usually just leave that at the default.
But actually I'm going to put this back to PSD.
So notice that I now have a completely different setup
than when we started.
Instead of TIFFs, we'll be creating PSDs.
The color space is now sRGB,
and the bit depth eight bits,
which both are more suited
for photos destined for online use than for print.
And the good news is
that you can come back in here at any time
and tweak your choices.
