2.1.2 General Merge to HDR Options
After the bracketed images are selected, you can customize the steps performed before merging the images,
such as aligning the images or removing 'ghosts'� Refer to the following list for a description of the options
when merging bracketed images:
Alignment Options
The Align source images option is checked by default�
It corrects misalignment problems when the camera
moves slightly between the bracketed frames� Hand- held
photographs have camera movement but even images
shot on a tripod may have some slight camera movement
as well, such as movement caused by wind, for example�
• taken on tripod: Select this alignment method
when you used a tripod to take automatic bracketed
photos� This method is fast, but corrects only for
horizontal and vertical camera movement, and not
for rotation or other types of motion�
(Note: This method was named 'by correcting shifts'
in Photomatix Pro version 4 and earlier�)
• hand-held: Select this method when you did not
use a tripod or when the images are dicult to align�
The 'hand-held' method corrects for several types
of camera movement, including horizontal and
vertical motion, rotation, and forward and backward
movement� When the 'include perspective' option is
selected, it corrects for every kind of minor camera
movement�
(Note: This method was named 'by matching features'
in Photomatix Pro version 4 and earlier�)
• Include perspective correction: This option requests
that the 'hand-held' alignment method corrects for
all types of camera movement, including rotation in
all three dimensions, as well as horizontal, vertical,
forward, and backward motion�
• Crop aligned images: This option removes the unneeded
borders resulting from alignment adjustments� Unchecking it
disables this, so that the resulting image has exactly the same width and height as the source images, but
may have white areas around the edges��
• Maximum shift: Sets the maximum mis-registration shift that the alignment attempts to correct for,
expressed as a percentage of the image dimensions� This setting does not need adjustment in most
cases� A situation when adjusting this setting may be useful is when the camera barely moved between
the bracketed shots� In this case, setting a maximum shift lower than 12% will restrict the number of
alignment corrections searched, thereby reducing the risk of selecting an improper alignment correction�
The Align source images option should not
be checked when your source images are
stitched panoramas or when they are "fake
exposures" derived from a single RAW le.
