How to do HDR:Could you detail how you stitched the panoramas shown on your samples page?
The panoramas shown on the examples page of this site have been stitched with Panorama Tools (also known as PanoTools).
In order to produce identically stitched panoramas per exposure, we did the following:
1. Loaded the images shot at the middle exposure into PTGui
2. Set the control point and stitched a first panorama for the middle exposure
3. Saved the project file (.pts)
4. Then for each one of the other exposure sets:
– Loaded the images belonging to the same exposure into PTGui.
– Selected Apply Template and chose as template the project file created for the middle exposure.
This gave us one panorama at each exposure level. We then processed the differently exposed panoramas in Photomatix Pro.
Important note: the Align Images option should always be unchecked when processing panoramas that have been rendered at different exposures, that is when processing in Photomatix already stitched panoramas, one panorama per exposure.
For the two panoramas processed with the Tone Mapping tool, we also used Enblend, applying it to the differently exposed panoramas. Enblend was particularly useful in this case as it removed the stitching seams that the tone mapping tool would otherwise have enhanced as local details.
One note about using Enblend with Photomatix. The TIFF file produced by Enblend should be flattened before processing it in Photomatix. If you intend to use the tone mapping tool, then it is recommended to ensure that the transparent background becomes black (i.e. pixel values at 0) and not white when flattening the image, or even better to crop the panorama.
