Don't use a smart phone camera for it a decent dedicated digital camera will correct for that optically in the lense, but you are right that is an issue for smart phone cameras due to the physical lense size.

No it would not produce parallax that the is the point of using a photo copy stand. That is how Profesional photographers have been copying photographs without the negatives since the beginning of photography it's a rig designed to prevent exactly that.Now the down side is a good photo copy

On the first update of a newly installed system, there is SL signing keys that have to be installed. Yum prompts for confirmation. Is there a way to install the keys before the first yum update? Are they in an rpm somewhere? Thanks.
