Considered taking the 4x5 with me on an upcoming European trip and made several contacts with Fed Ex and DHL concerning sending myself film overseas to avoid the airport hassle that has been discussed here ad nausium. What I found out rather set me back a bit. First it is very expensive. Two boxes of 4x5 sheet film (100 sheet box of FP4+ and a 50 sheet box of Velvia) would run about $80 for a three day delivery and about $72 for a week delivery (Colorado to Germany). Second, it is completely up to customs of the country you are sending it to as to the control of the screening that could take place. In other words, you take your chances with no guarantees on the receiving end.
Domestically, Fed Ex can tell you straight faced that they do not X Ray packages but it is out of everyone's hands in Europe. Labels on the outside or not it is a crap shoot at best. At least they are being straight about it.
My options as I see them are to suck it up and let them X Ray it at the airport and hope for the best, try to acquire film at my destination without getting killed on the price or purchase post cards and focus (no pun intended) on schnitzel and beer (not necessarily in that order). I do not see the courier options as viable and I have no expectations that I can talk my way through the airport with a hand check. Been there and tried that.
Any of you jet setters with LF cameras have any recommendations?
