How to resize an image using Lightroom
In Lightroom you don't really resize an image,
you export a copy of your original
at a particular size
leaving your original untouched.
Right now you're looking at the Library module
in Lightroom
and I have some thumbnails up.
I'm going to select some images by holding down COMMAND
if you have a PC you hold down CONTROL.
I'm going to select these 4 images\
just to show you I can select
non-contiguous images
and I can also resize verticals and horizontals
in the same action.
Once I have them selected I come down here\
to the EXPORT button on the lower left.
I click that.
And I pay attention to the dialog box
from top to bottom.
EXPORT LOCATION? Where do I want to put these?
It's going to the desktop, I can create
a new folder right now through Lightroom
and I'll just call this DEMO.
I can rename the files.
Right now they have my own filing system
tile names.
But I can rename this
and I can go in to edit the custom settings
I'll just take this out so we
can start from scratch.
Let's say I want to name these
with my last name, an underscore,
my first name, and then an underscore.
I can just type those things in and
each file name will get that at it's beginning
and then I can go to SEQUENCE AND DATE
and I can choose a 2-digit sequence
and I can just click INSERT.
Oops, I already had it there. Sorry.
I can highlight that and delete it.
So there I have mueller_paul_ and a 2-digit
sequence.
And I'm done with that.
FILE SETTINGS
This is where I decide if I want to export
as a a jpg, as a Photoshop file (psd),
a TIFF, a Camera RAW.
For now I'm exporting JPGs and this is how
you will export your images for assignments.
This is also a good way to export images
you want to email somebody or
put on your website.
COLOR SPACE sRGB is a good color space.
And now I want to resize in IMAGE SIZING
You'll notice it doesn't say "resize"
I keep saying that, but...
We're going to size it to 1000 pixels on the long side.
You have these choices to resize by the width
& height,
by the dimension,
by the long edge,
by the short edge,
or by the megapixels.
If I select LONG EDGE
and I type in a value here,
in this case I've typed in 1000 pixels,
my images will all be resized so that the longest
of the edges is 1000 pixels.
If it's a square image it will be 1000 by
1000 pixels,
if it's a vertical image it'll be 1000 by whatever the short edge is.
If it's a horizontal it will be 1000 wide
by whatever the height is.
So this won't turn a rectangular picture into a square picture.
72 pixels per inch is a good screen resolution.
The only other thing I want to pay attention to here is
\ \
WATERMARKING
Please don't watermark your images for this
class.
After export I can have it do nothing,
or I can have the images open in Photoshop,
or in Mail or in something else but for now
I'm doing nothing.
I click EXPORT and you can see up here
there's a progress bar that says
"Exporting 4 files"
and we'll let that complete.
I can see on my desktop that
Lightroom has created a folder on my desktop
called "demo" and I'm going to open that now
Demo - and here are the 4 images
and each one is properly sized to be
1000 pixels on the long side.
Thank you.
