Applying Image Effects 75
For good results, it's important to bear the following points in mind:
• Many modern cameras offer auto-bracketing which automatically
takes several shots at different exposure levels. A two-EV spacing is
considered to be optimum for most occasions. Alternatively, shoot
with manual exposure set.
• Always shoot the same scene! Your output is based on a composite of
the same scene.
• Take as many shots as is needed to cover your required dynamic
range.
• Use a tripod for optimum camera stability. Also avoid photographing
objects affected by windy conditions (e.g., moving tree branches).
• Ensure Aperture priority is set on your camera (see your camera's
operating manual for more details).
The HDR merge is a two-stage process, firstly to select the source files (JPG or
raw) for merging, and then performing the merge itself after having adjusted
merge settings to optimize the output. The process can be carried out directly on
source files without loading them into your project in advance.
PhotoPlus lets you optionally save the merged HDR image to one of several
formats (namely OpenEXR, HDR and HD Photo), which can be opened at a
later date, saving you from having to align and merge your original images
again.
