Lightroom simplifies color management by displaying colors using device-independent color spaces. This means that
all you need to do before working in Lightroom is to
Calibrate your monitor . Then, when you’re in Lightroom, choose
color settings or color profiles when you’re ready to output your photos.
How Lightroom manages color
Lightroom primarily uses the Adobe RGB color space to display colors. The Adobe RGB gamut includes most of the
colors that digital cameras can capture as well as some printable colors (cyans and blues, in particular) that can’t be
defined using the smaller, web-friendly sRGB color space.
Lightroom uses Adobe RGB:
• for previews in the Library, Map, Book, Slideshow, Print, and Web modules
• when printing in Draft mode
• in exported PDF slideshows and uploaded web galleries
• when you send a book to Blurb.com (If you export books as PDF or JPEG from the Book module, however, you can
choose sRGB or a different color profile.)
• for photos uploaded to Facebook and other photo-sharing sites using the Publish Services panel
In the Develop module, by default Lightroom displays previews using the ProPhoto RGB color space. ProPhoto RGB
contains all of the colors that digital cameras can capture, making it an excellent choice for editing images. In the
Develop module, you can also use the Soft Proofing panel to preview how color looks under various color-managed
printing conditions.
A Image is edited in the Develop module. B Image's color values are translated to the color space of chosen print conditions C Lightroom displays
proof profile's interpretation of the image's color values.
When you export or print photos from Lightroom, you can choose a profile or a color space to determine how the
colors you see in Lightroom will appear on the device you’re sending the photo to. For example, you can export using
sRGB if you’re going to share photos online. If you’re printing (other than Draft mode), you can choose a custom color
profile for your device.
See File Settings and Set print color management .
Calibrate your monitor
To help Lightroom display colors reliably and consistently, calibrate your monitor. When you calibrate your monitor,
you are adjusting it so that it conforms to a known specification. After your monitor is calibrated, you can optionally
save the settings as a color profile for your monitor.
1 If you are calibrating a CRT monitor, make sure it has been turned on for at least a half hour. This gives it sufficient
time to warm up and produce more consistent output.
2 Set the ambient lighting in your room to be consistent with the brightness and color of the lighting conditions that
you usually work under.
