Workflow for Panoramas

18 June 2011 11:44 | Comments: 0 | Categories:

A suggested workflow for handling panoramas in Lightroom and PTGui.

In Lightroom, create a folder for panoramas, and a subfolder for each one, named by the number of the first image in the panorama sequence. Move the images to the appropriate folder.

In PTGui, for each panorama set:

Load the images and create the panorama. (Or open existing project). Use Equirectangular setting, and use sliders in the editor to remove unwanted whitespace. Note the horizontal field of view for use when generating the dynamic panorama.

Save:

1. TIF file for use in creating dynamic panoramas. Say height 1024 pixels. 8 bit TIF.

2. JPG for loading to ZenPhoto album, say width 2048 pixels, 70-80% quality.

Save both in the same folder, and use the same folder for all panoramas.

Save as PTGui project.

To generate dynamic panorama, use tools > publish to website.

If doing one by one, set horizontal field of view as noted earlier, or if doing a batch set to a suitable common number (180?). Use Equirectangular projection, and leave files in the same folder as the source files.

Save again as PTGui project.

Now move the large JPG's generated earlier to an appropriate ZenPhoto Album and upload, and from ZenPhoto admin generate links to the .htm file for the each dynamic panorama.

Note that if adjustments are needed to the final panorama image, import the TIF into Lightroom and apply develop settings as required, and export, either overwriting the first TIF or generate a new copy.

You will then need to generate the JPG for Zenphoto either with other export, or using a Photo Editor (Irfan) to resize the TIF and Save As JPG.  The dynamic panorama will also need to be regenerated using this improved TIF.

Note from David R. "I would get rid of the black corners. You can clone them out, or use the Transform tool in Photoshop to pull the corners out. If you have Photoshop I can talk you through the process of stretching the canvas. Quite useful too when there are images that have distorted corners as occur quite often when using stitching software. You can literally stretch them straight."
