4.9 … create spherical QTVR panoramas (continued)
4.9.3 Post production on spherical QTVR panoramas
Please note that for software versions 3.2 and higher the blending of a 360° panorama
can be done automatically in tab “Camera parameters/blending 360°”. This section
explains how to do the blending manually.
In certain situations QTVRs will not match at the beginning and the end of the
panorama, or in other words, there will be a seam. This is due to changing light
conditions at the beginning and the end of the scan (for example a cloud passing in
front of the sun). To overcome this issue we recommend retouching the image in
Photoshop according to the following procedure:
1. Capture the panorama at 400°
For a smooth blending the original image should be more than 360°. Typically 400° will
give good results.

Please note that the lens-specific mapping function and image correction is only
applied in the Seitz Roundshot D3 software. These parameters are saved with the DNG
file metadata and are then reloaded when converting the raw file into RGB in the Seitz
Roundshot D3 software or the Seitz raw converter. For more information on post
production please refer to chapter 5 “Post production”.
The spherical QTVR panoramas must be converted from dng into RGB
(TIFF, JPEG) in the Seitz Roundshot D3 software or in the Seitz raw
converter. Converting them in another raw converter (camera raw,
Lightroom) will not allow calibrated results.

2. Open the panorama in Photoshop
and extend its canvas
Increase the canvas size to obtain a white
background to the left of the image. The
extension size should exceed area above
360° (in this example > 40°).
