Make sure the vertical FOV on your Epic 100 is set to one of the values available in this calculator when you set up for a panorama. No intermediate values will work. You must record it for later use in this calculator. Set the Epic 100 FOV as you normally would except before clicking “OK” to the measurement, reduce it to the next lower value available in the calculator (e.g., if you measure 27 degrees, move the head so it reads 25 degrees and write it down).

Also, when setting up a panorama, just before setting the lower right hand corner make sure that the camera is at the midpoint of the last image by doing the following;

  1. Record the indicated number of columns and rows. Pan the camera to the left so that the number of columns just changes to one less than the original indicated number and identify a landmark on the right edge of the image.
  2. Pan the camera to the right so that the number of columns just changes to one more than the original indicated number and identify a second landmark on the right edge of the image.
  3. Pan the camera back to the left until the right edge is at the midpoint between the two landmarks you identified.
  4. Pan the camera up so that the number of rows just changes to one less than the original indicated number and identify a landmark on the bottom edge of the image.
  5. Pan the camera down so that the number of rows just changes to one more than the original indicated number and identify a second landmark on the bottom edge of the image.
  6. Pan the camera back up until the bottom edge is at the midpoint between the two landmarks you identified.
  7. Click "OK" to finish defining the panorama range.

Explanation of the data fields:

GPS - Insert the GPS coordinates of your panorama here. This is passed straight through to the XML output and is not used by the calculator.

Pano Start and End Time - Use this format to enter the times the first and last photos were taken. This is passed straight through to the XML output and is not used by the calculator. The start time is also used for the timestamp for each image in the XML.

Columns and Rows - If you didn't write these down when you took the panorama you will need to figure them out from your photos. This is critical information used by the XML calculator. An integer number.

Crop Factor - The ratio of the size of your camera's CCD compared to a full frame camera. This value is 1.0 for a full frame camera, 1.2 for an APS camera, etc. The Canon S100 ratio is 4.5543806. This is passed straight through to the XML output and is not used by the calculator.

Aspect Ratio - The aspect ratio of your camera, the ratio of horizontal pixels to vertical pixels. This is critical information used by the XML calculator.

Focal Length - The lens focal length in the image Exif data. This is passed straight through to the XML output and is not used by the calculator.

Vertical Field of View (FOV) - Recorded from the Epic 100 at the time the panorama is made. This is the most critical information used by the XML calculator. The amount the head moves between photos is determined by the Vertical FOV. It is not a linear or continouous function, however, so careful measurements were made and a lookup table created for 16 different FOV values using an Epic 100, firmware version F020100130.

Time/Picture - The pause time for each photo. This is passed straight through to the XML output and is not used by the calculator.

Bracketing # Images - If you are capturing multiple images at each location (e.g., HDR pano), enter the number of images taken at each location. If not, enter 1. This is critical information used by the XML calculator.

Pano Type - The panorama type selected on the Epic 100. This is critical information used by the XML calculator.

Horizon Row - The calculator will set the angle of the horizon row at 0 degrees. This information used by the XML calculator but you can leave it at the default and adjust it in the stitching software if needed.

Orientation - Only lanscape is supported at this time.

Picture Ordering - The picture ordering option selected on the Epic 100. This is critical information used by the XML calculator.
