Assume I have a traditional panorama. I use a spherize technique (e.g., in Photoshop) to produce a spherical image. Some time later, I want to take the spherical image and get back the landscape (ideally via Photoshop).
Assume I don't have the .pst that was used to create it, only the spherical image file.
Any recommendations on a Photoshop step-by-step to achieve this? Thanks.
