K|Lens provides this first images from the prototype objective: And the generated depth map: As first I made a small animation with http://depthy.me (The link no longer works.): And then I had some fun with GIMP/g'mic: 1. Focus to the background. 2. Focus to the foreground: For the two images above I simply used the depth map as mask. here is how it looks in GIMP:

This two images are again more then 200 years old and now we can view them in VR. The first image is “A Circular View from the Balloon at its greatest Elevation”, featured in Thomas Baldwin’s Airopaidia (1786). https://archive.org/details/Airopaidia00Bald/page/n74 You can read more about this image here: https://publicdomainreview.org/2016/07/20/for-the-sake-of-the-prospect-experiencing-the-world-from-above-in-the-late-18th-century/ The 360x180° panorama created with Hugin and GIMP (I made the sky bigger.) Use this link to view the panorama with the DayDream: https://photos.app.goo.gl/zYjsLDvNJF4cGNzd8 The second image is on of 31 illustrations Marc-Théodore Bourrit made between 1779 and 1796. http://www2.unil.ch/viatimages/index.php?lang=en&projet=viaticalpes&module=image&action=detail&IDImage=129 The 360x180° panorama created with Hugin and GIMP (I rotated the text and filled the sky.) Again here the link to view the panorama with the

 I used my last tutorial but this time I took an recent photo from inside the Dresden Frauenkirche I found here: https://www.flickr.com/photos/w-b-r/37537092641 (Werner Reutemann CC BY-NC-SA) The image converted to an 360x180° panorama: And now you are able so stand inside the dome of the Dresden Frauenkirche : https://photos.app.goo.gl/AkzLWgz4UH1ZNzzk7

After I have created panoramas that I can view with a DayDream VR headset, I have now added sound to the image. CC BY Maurizio Pesce  How to create the panoramas: Tutorial: Dresden 1824 - Inside an image from Carl August Richter Update: Dresden 1824 - A 195 Year old image as 3D Wireframe in VR Tutorial: Dresden 1824 - Inside an image from Carl August Richter - Improved I used the sound from this video I found in Wikipedia: https://commons.wikimedia.org/wiki/File:Stadt_Wehlen_in_der_S%C3%A4chsischen_Schweiz.webm Then I used the Transmageddon Video Converter to extract the sound from the video and directly convert it to MPEG-4 AAC. I used this setting: MPEG4 Sound: MPEG-4 AAC Video: No Video Then I renamed my images to Dreden_left.jpg and Dresden_right.jpg and dropped all three files into used this online tool: https://cctoolkit.vectorcult.com/# And this is the result (You can only hear the sound with the headset, not in the browser): https://photos.app.goo.gl/

Thanks to this posts on twitter from Bruno Postle i have now a method how to results from the last tutorial : The first and the last steps are the same. Center the image. (Alternative you can measure the centre an enter the values in Hugin). The new thing is to use Hugin instead of the "Little Planet" plug-in in Gimp Start Hugin Change to the expert mode. (Interface->Expert) Add the image via drag and drop or this button:  Cancel this dialogue: Double click on the image: Change pitch to -90: Change the "degrees of view (v)" to 212: Here you can even the image centre shift, if you have not centred the image before in GIMP. Now go into the Preview mode: Now change the preview mode to " Stereographic":  And in the "projection" tab the "Field of View" to 360x180 Equirectangular: The preview should now look like this: Now you can go back to the "Assistnt" tab and hit the "3.
