Ok, a ton of guides already exists and I do not plan to do another one but I want to leave you with my experiences as I do not want to use the Dji Go 4 app for stitching the sphere – I work with the SD full image files.
The tool that I use for stitching is Hugin which is open source. I bet there are easier and better alternatives but as I just do it more for fun I won’t pay a $100 for a license. Hugin can be downloaded here http://hugin.sourceforge.net/ and is available for many operating systems.
This is the guide that I used to familiarize myself with the Hugin software
- I did not create a Stereographic projection but I used an Equirectangular output from Hugin
- I exported it as an JPG file
- Post export I imported it into GIMP to make sure that it follows the required 2:1 dimension and consequently resized the canvas by modifying the height to be half the width. Expand at the top of the image
- Use an EXIF editor to modify the adjusted JPG. I’m using an online editor https://www.thexifer.net/ to do this
- Make sure that the following values are adjusted
- CroppedAreaImageHeightPixels = new full height
- CroppedAreaImageWidthPixels = new full width
- CroppedAreaLeftPixels = 0
- CroppedAreaTopPixels = 0
- FullPanoHeightPixels = new full height
- FullPanoWidthPixels = new full width
- ProjectionType = equirectangular
- UsePanoramaViewer = true
Now you are done and ready to upload it to Facebook or Google Photos to be shared with your friends.
Note: I had some challenges to update the fields in the EXIF online tool but it worked if I first cleared the file of the EXIF metadata prior to inputing the new values.
I’m showing an example in the post below. Click image to view it in full screen.
