A 360-degree photo can be used not only to capture a scene in 360 degrees, but also to present conventional photos as an immersive 360-degree photosphere. Here is a sample, where I used photos of our daughter growing up:

It's actually very easy. Here's how to do it.
1. Create a canvas that has a ratio of 2:1 (the width is exactly twice the height). It can be a blank canvas or you can fill it with a pattern*. Alternatively, you can open an existing 360-degree photo in equirectangular JPEG format.
*Note that if you use a pattern or other non-360 image, it will converge and be distorted at the top and bottom of the photosphere.
Here is the sample photo I used as my canvas:
2. Use any photo editor (e.g. Photoshop) to paste your photos onto the canvas but stay within the middle 1/3 or middle 1/5th band. If you paste it farther above or below that, the photo will look too distorted.
3. Upload or open the resulting photo in a 360-degree viewer or app. That's all!
Suppose you want to create a complete photosphere, with photos even at the top and at the bottom. That's possible too with the help of software such as Pano2VR, which I'll post about next time.
