4.1 Exposure Bracketing to Capture HDR images
When your panorama has areas with significantly different
amounts of light, such as shadows, neutral colored rock,
and blue skies, a single exposure will not yield all of the
detail that you can see with your own eyes. This is
especially true for panoramas that cover a large field of view.
You can improve the overall exposure by capturing multiple
photographs with different exposures for each position. You
do this by using the EPIC Pro 'Brackets' setting and the 'EV
Step Size' setting. The panorama shown above is a good
example because it has a very large horizontal field of view
with areas that have shadows.
