Working with single-channel grayscale images
Grayscale mode images from Photoshop have no color data, but you can make tonal adjustments to them in
Lightroom using the tone adjustments in the Basic panel or Tone Curve panel. You can also apply color toning effects
using the options in the Split Toning panel. Lightroom handles the photo as an RGB image and exports it as RGB.
Retouching and correcting flaws
Rotate or flip a photo image in the Develop module
•
To rotate a photo image in 90 degree increments, choose Photo > Rotate Left or Rotate Right. To rotate a photo to
less than 90 degrees, see “Crop and straighten a photo” on page 81. The photo rotates in a clockwise or counter-
clockwise direction around its center point.
•
To flip a photo image horizontally from front to back so that you’re looking at a mirror image, choose Photo > Flip
Horizontal. Objects that appeared on the left side appear on the right side, and vice versa. Text in the image will
show in reversed mirror image.
•
To flip a photo image vertically from front to back so that you’re looking at a mirror image upside down, choose
Photo > Flip Vertical.
Crop and straighten a photo
The toolbar in the Develop module contains tools and controls for cropping and straightening photos. Lightroom
crop and straighten controls work by first setting a crop boundary, and then moving and rotating the image in
relation to the crop boundary. Or, you can use more traditional crop and straighten tools and drag directly in the
photo.
As you adjust the crop overlay or move the image, Lightroom displays a grid of thirds within the outline to help you
compose your final image. As you rotate an image, a finer grid appears to help you align to the straight lines in the
image.
