"When making a portrait, my approach is quite the same as when I am portraying a rock. I do not wish to impose my personality upon the sitter, but, keeping myself open to receive reactions from his own special ego, record this with nothing added: except of course when I am working professionally, when money enters in,—then for a price, I become a liar..."
— Edward Weston, Daybooks, Vol. II, February 2, 1932
I am pretty sure that a parcel from Canada would have to go to the US via Seattle so I don't think it would make a difference.
I order from Beau Photo a lot, they are awesome to deal with. If you are ever really stuck for something I can probably get it for you and drop it off at the Skagway post office. Although who knows, that might get sent to you via Seattle as well.
