Smart Backdrops in Curvy is a method to line up several photos of a single object ready to sculpt from them as references.

Smart Backdrop Tutorial
Ideally you would sculpt from exact Front/Side/Top references but sometimes these are not available, and instead you have a group of photos from various angles and distances.
Using smart backdrops you mark the photos with image targets, and try and find matching 3D targets in your scene.
On the Backdrops panel, below the buttons, is a list of images you have loaded. Just click to select which you want to activate.
The active image is rendered in the special "Backdrop View" which you can choose from the "3D View" menu in the top right of a viewport.
Load
Loads a new Backdrop from an image on disk.
Reset
Moves the Backdrop image back to the centre. Useful if it is badly distorted by accident.
Locate
Uses image and 3D targets to try and locate the best position for the backdrop in space, to match the targets.
7.1. Targets
3D targets are placed by pressing F1 to F9 with the mouse in the right location on a 3D view.
Image targets are placed after selecting a backdrop, by pressing 1 to 9 keys with th emouse in location over the image.
Once placed image and 3D targets are linked with a line to show their connection.
Free
Select "Free Targets" to place. These are single points anywhere in space.
Centre
Select "Centre Targets" to place. These targets are forced to lie on the centre line - useful when you know your reference has a strong symmetry about the middle.
Left
Select "Left Targets" to place. These are paired with a "Right Target", and forced to be symmetrical. Again useful if you know your reference has symmetries.
Right
As for "Left" but controls the flip side of the symmetry.
