Transforming and Retouching
To adjust the perspective of a composition:
Select the Use Perspective option.
1
Select the vanishing point tool (
2
on an image in the work area to make it the
vanishing point image.
The vanishing point image is used to correct the
perspective for the entire composition and has a
light blue border when it is selected (as opposed to
a red border). By default, the first image you drag
into the work area is the vanishing point image. In
an automatically assembled composition, the
middle image is the default vanishing point image.
There can only be one vanishing point image per
composition.
If necessary, adjust the position of the non-
3
vanishing point images. A non-vanishing point
image has a red border when it is selected (as
opposed to a blue border).
When you apply perspective correction to a
composition, the non-vanishing point images are
linked to the vanishing point image. You can break
this link by separating the images in the work area
or by dragging the vanishing point image back to
the lightbox. Once the link is broken, images
return to their original shapes.
The perspective correction only works up to
approximately a 120° angle of view. For a wider
angle of view, the Use Perspective option should be
), and click
deselected.
To change the perspective of a composition,
select the vanishing point tool, and click on a
non-vanishing point image in the work area. Notice
how the perspective of the composition changes
depending on which image is the vanishing
point image.
To rotate an image in the work area:
Select the select image tool ( ), and click on the
1
image you want to rotate.
Select the rotate tool ( ).
2
Click near the edge of the image and drag in a
3
circular motion around the center of the image.
Hold down Shift to constrain the rotation to
45° increments.
To clear a composition:
Hold down Alt (Windows) or Option (Mac OS),
and click New. All images in the work area are
returned to the lightbox.
Previewing a Photomerge composition
The Cylindrical Mapping and Advanced Blending
options are used to process the final image. The
results of applying these options are visible only in
Preview mode or in the final, generated image.
