Images can contain embedded data, providing additional information
about the image. This is called metadata. By default PTGui will copy
certain metadata from the source images to the generated panorama:
- The shooting date of the panorama: PTGui will use the earliest
timestamp found in all source images of the panorama.
- Exposure data: exposure time, aperture and ISO sensitivity.
This data will only be embedded if all images have identical
exposure. If separate HDR blend planes are output, the blend
planes will have the exposure data of the source images used for
that blend plane.
- ICC color profile: the color profile will be copied from the
source images, but only if all images have the same profile.
- GPS location: if available, the camera GPS coordinates are
copied from the source images. If the source images have
different coordinates, the average is taken.
- Image orientation: if the shooting direction (compass angle)
is available in one or more of the source images, this will be
embedded in the panorama. PTGui will correct for the yaw offset
of each source image, so the image direction metadata refers to
viewing direction of the center of the panorama.
- For rectilinear panoramas PTGui will embed the FocalLength and
- For equirectangular panoramas PTGui embeds the Photo Sphere
XMP Metadata, as defined by Google.
PTGui currently only writes metadata to JPEG and TIFF files.
The following settings can be overridden or added in the Metadata
window. This is accessed by clicking on the Metadata button in the
Create Panorama tab:
Camera Location: the GPS coordinates of the camera. If Use
EXIF data of source images is selected, the coordinates are
copied from the EXIF data of the source images, if available.
Otherwise coordinates can be entered.
The location should always be entered as the latitude followed by
the longitude, separated by a comma. Negative coordinates are used
for the southern hemisphere and for eastern longitudes. All common
coordinate formats are supported: coordinates can be entered as
fractional degrees, as degrees and fractional minutes, or as
degrees, minutes and seconds. A period (.) should be used as the
decimal separator. The symbols ° ' " are used to separate degrees,
minutes and seconds.
For example, the following coordinates are valid and all refer to
the same location:
Orientation: enter the viewing direction of the center of the
panorama. 0 degrees is north, 90 degrees is east, etc. Or choose
Use EXIF data of source images to copy this data from the GPS
Image direction of the source images (if available).
Resolution: this is the resolution value (in pixels per inch)
that is inserted in the metdata. The resolution value is just an
indicative value suggesting the number of pixels to be printed in
one inch. It does not change the actual size or level of detail in
the resulting image, but it can be useful in workflows where the
physical dimensions of the resulting printed image need to be
