Prisma is a very popular app that allows you to apply distinctive art style filters to a photo or other image. Prisma's effects can also be applied to a 360-degree photo. Here's how.
Ordinarily, a 360-degree photo is intended to be more realistic and immersive. However, there's nothing that says it can't also be used with more creative effects.
Here's how to use Prisma on a 360-degree photo:
1. Fit the equirectangular panorama to a square using an app such as Instafit.
2. Apply the desired Prisma filter.
3. Crop the image again to a 2:1 equirectangular panorama.
The image is now ready for viewing as a 360-degree image, but with a Prisma filter applied. Here is a sample:
Here is another example, with animation: https://instagram.com/p/BI3CQyGglmO/
When viewed on a VR headset, the effect is like stepping into a painting.
You can also use the Prisma effect on a little planet, rabbit hole, or a cropped version of the 360 photo.
