What should we wear?
Try to coordinate what colors your family will be wearing along with what type of background you will be using. Also do not wear clothes that have a lot of detail in them because this can distract from the portrait.

What do I need to supply?
Depends on the location but typically just your smiles.

What do you mean by on-site viewing?
After we take a few pictures we can sit down with the laptop and get a rough idea of what your pictures look like.
