How to add mandatory Photo Sphere meta data to an equirectangular image (Photoshop CC 2014)

Preface

Last year Google added a new feature to their set of web based applications. Publishing geo located spherical panoramas (aka Photo Spheres) on Views.

In another article, Markus already described the complete workflow which is needed to publish a panoramic image on Views and embed it into your website.

I already described different methods of adding mandatory Photo Sphere meta data to an equirectangular image in a second article. One of the methods described a custom meta data panel which could be used within Photoshop CS6 and Photoshop CC to read and write the photosphere meta data.

As Adobe changed their specification for creating meta data panels for Photoshop CC 2014, I redid the description…

Note for downloading the XML files

Depending on your browser it could be the best option to click the XML download link and use the context menu to save the link as XML to your local computer!

Custom photo sphere meta data panel for Photoshop CC 2014

First you have to identify the proper location for the File Panels. On a Windows system running PS CC 2014 the files are located in

C:\Users\[Username]\AppData\Roaming\Adobe\XMP\Metadata Extensions

or directly using the appropriate environment variable:

%USERPROFILE%\AppData\Roaming\Adobe\XMP\Metadata Extensions

PS CC 2014 running on Mac OS uses the following location

[Username]/Library/Application Support/Adobe/XMP/Metadata Extensions

Navigate to the location and create a sub directory named

Photosphere

with two subdirectories named

schema

and

view

Change to the newly created directory ‘Photosphere’ and create a file named

manifest.xml

with the following content (or download the file here):

The properties ‘SourcePhotosCount’, ‘FirstPhotoDate’ and ‘LastPhotoDate’ are optional values for a photosphere.

Then open the file info dialog of Photoshop CC 2014. When all the meta data is missing, the new panel looks like this on a german installation:

And the following screenshot shows the panel, when the meta data fields are already populated.

Bayernpark in November

This panorama has been shot from a 6m high pole using the innovative Sony ILCE-QX1 ‘camera’. I took on e image in each cardinal direction and an extra shot to get rid of my shadow. For a more detailed description of the camera and lens setup see this post from PanoTwin Jürgen.

Court House Courtyard

This panorama has been shot handheld with the innovative Sony ILCE-QX1 ‘camera’. I took one image in each cardinal direction and an extra shot for zenith and nadir. I held the camera obove my head to reach a higher view point and released using my smart phone. For a more detailed description of the setup see this post from PanoTwin Jürgen.

The maximum equirectangular panorama size of this setup is about 10000×5000 pixel according to PTGui. However the one you see below has been downsized to 6000×3000 pixel before publishing it on Google Views.

Colonnade at new portal of main cemetery

The new portal of the main cemetery of Frankfurt am Main was built 1908. It incorporates a chapel, a crematorium, a morgue and a hall to host funeral services.

Technique
The panorama was taken with my double monopod construction which was extended to a height of approx. 2.5 meter (appx. 8.2 ft). Stitched from four images taken with a Walimex (Samyang) 8mm fish eye lens on a Sony A7. I took four images around and an additional shot for the floor.
