Additional GigaPan Stitch Options
To access these additional stitching options click on the 'Options' button on the left
side of the stitching software.
Image shooting order
Your options are columns - right, columns - left, rows - down, or rows - up.
The GigaPan Stitch default is columns - right; remember to change it in the stitching
software if you change your shooting order with the EPIC Pro.
Combine images in draft mode
Draft mode causes seams between images to be visible, but speeds up stitching some.
This option removes the blending step of the process, which speeds up stitching and
could be useful for quickly checking what your image will look like.
Build panorama at 50% scale
Using 50% mode will cause a loss of detail, but speeds up stitching and results in a
gigapan with 1/4 as many pixels as normal. This could be useful for larger images
that you may be printing instead of zooming into, so the extra detail isn't necessary;
or when you know that your input images are a little blurry; or if you'd like to save
upload time. Keep the 50 megapixel minimum limit on uploads in mind, however. For
example: if normal stitching would have yielded a 160 megapixel panorama, the '50%
scale' option would generate a 40 megapixel panorama, which would be too small to
upload to GigaPan.com.
Use larger blending region
A larger blending region is useful if transitions between images appear too hard-edged
and abrupt.
Mercator projection instead of spherical/equirectangular
The mercator projection doesn't distort objects above or below the horizon, but
cannot be used in Google Earth.
