I also agree that airport security guys most probably can not "crank up" the intensity of the X scanners - I would say simply because of safety reasons. Now - if they would be able to change the speed under which is the luggage passing the scanner - then they could achieve the same result - more exposure of the luggage.
My own experience from flying to New Zealand abd nack - my films (only ISO 100) were scanned 9 (!) times (at EVERY airport .. hard to understand) but had no problems at all.
But once this is a "travel kit" thread - here is my travel kit to the above mentioned New Zealand trip.
- Olympus Xa
- Rolleiflex T
- Tachihara 4x5 + 75/4.5, 125/5.6, 240/9 and 400/8
- carbon tripod + small alu table to tripod (Manfrotto)
- Digisix light meter
- changing tent
- film holders, all posible acc.
- film 😉
most of the above was in carry-on ...
It was great actually - though the 4x5 was too slow at times and uncomfortable in non optimal weather (a small "field" monorail with more sturdy standards could be faster to use, but would be heavier).
I may go with a 35 RF and MF RF next time (GSW690 could be an option).
Actually - I think people could comment not only WHAT they used but also HOW it worked for them ...
