Blind Lens

Bought myself a MacBook, camera etc yesterday so thought I would try infinity photo. Despite following the instructions in the first tutorial nothing I do seems to work. I am completely baffled by the jargon and there seems nowhere where an explanation can be obtained that is written or spoken in plain English. Looks like the time is nigh to consider the purchase to be an error and delete it from the system. By the way this is the first time I have ever used a computer or digital camera
