Again, I appreciate the response.
Although natural lighting is theoretically possible I wouldn't be able to book the 'shoots' when I want to-it would be time & day to suit the client. Therefor lighting would be necessary.
I think 'cold' light would be better but having never used iether I'm open to suggestions.
My initial thought was flash with umbrellas but the link to Clive seems to indicate constant light (lightbox?) being preferred.

Lense question.
With the limitations of room length (and the tripod will take some of that up) what is maximum wide angle you think I can use for portraits/families etc.
