These are photographs that lead to spheres. As such, they are a sort of “portal” into another experience, in this case, one that reveals more about the location that the photograph was taken. Click the picture to see an active version of it. That is the port. Click again to enter the experience.

Photoportal of a waterfall, hanging on the wall. Entering the portal lets you see the rest of the canyon from the same location that this was taken. The waterfall also appears closer to what you would see if standing there, with the flowing water frozen in mid-fall.
Photoportal of a rose, hanging on the wall. Entering the portal lets you see the entire rose garden from the same location that this was taken. The rest of the flowerbed containing this plant becomes visible, as well as the extent of the rest of the garden.
This photoportal shows a cluster of flowers nestled in a bush. Entering the portal reveals the forest path along which this bush is growing.
This photoportal shows a boardwalk leading into a wetland forest. Entering this portal allows you to see where the boardwalk comes from, and what the scene would look like if you were standing there.
