Afterall Photo lines up your "after" photo with your "before": the earlier shot sits on the live camera as a see-through ghost, so you can find the same spot again.

Version 1.2 adds spots. One project can now hold every room of a refurbishment or every corner of a garden, each with its own before, after and ghost, and the Reveal plays them in turn. Every export now ends on the result, a repeat dial plays the change up to four times, and the Afterall mark can sit in any corner.
