In this article I will share my experiences with this technique, scribble together some things I found out and I will add a couple of links to help you get more out of it.
Selecting a Panorama or Photo for Your Planet
When selecting a photo to start with you should keep the following things in mind:
* Select a panorama photo or a cropped landscape photo (aspect ratio at least 2:1, which means the width should be at least two times the height).
* The bottom area (bottom 25% or so) of the photo in most cases should have only very little detail (e.g. sand, asphalt, water). This area will later be in the middle of the picture and will also be distorted the most.
* The upper area (upper 25%) should also have only little detail, most preferably just one color (e.g. blue sky, night sky etc.).
* The left and the right border of the photo should neatly fit into each other (which is always the case for a stitched 360° panorama).
