Xray and tmax 400 am I in trouble?

Tmax 400, Neopan 400, and Neopan 1600 all survived the X-Ray machine upon entrance to Cuba. Oddly, they did not insist on scanning when I was leaving. Guess they are only concerned about what is being brought into the country.

Film is incredibly durable. No need to worry.

 

I took the last of some film stock that expired in 2005 through several airport scanners last week. During its lifetime, each roll has probably been through x-rays around six times, not including my recent trip. Plus it was five years out of date.

 

I developed it myself in chemicals that were also out of date. Shelf life was rated as 4 weeks, and I mixed it 8 weeks ago.

 

The results were lovely. Sharp, great colours, perfect density.

 

This is an example image, taken with a 1961 Rolleiflex with inaccurate shutter speeds, an uncoated lens and guesswork metering. Sometimes, the more imperfection you introduce, the more surprised you can be at the quality.

I have.

There was a bloke taking photos of 'the wall'.

The israelis knew he was doing it and when he went to leave town they ran his entire kit through the xray twenty of thirty times. That was back in the old days when you could turn up the xray equipment and do some damage.

These days with oh and s the modern equipment even the dentists dont always retreat behind the screen.

Why is it that no one points out that the advances have been in the record and the digital display side and that the rontgens have gone through the floor?

The comment above is so true, security line X-Ray is no big deal (under 800asa) but never check your film in your luggage. The baggage is checked with a far stronger x-ray device.

 

I always try to get my film developed immediately after it's shot abroad, just in case.

I have been in the position where I will have had 4 CT scans (plus a PET scan) in the space of the past 12 - 13 months. The CT scans are roughly the equivalent of 400 chest x-rays, which means that in total I must be looking at 2,000 chest x-ray equivalents in this period.

 

I haven't faded away yet, nor have I gone foggy :).

 

If you put your film into one of the clear security bags that airports like you to put your toothpaste in these days, and place the film in the plastic x-ray tray, it will get the minimal dose of x-ray that it can be given.

I have just returned from a business trip to Taiwan, my Tri-X 400 went through Heathrow, Bangkok, on the stopover, and Taipei airport scanners with no ill effects. These were the carry on scanners I would agree with others on the post never put film in the hold luggage it does get a much stronger dose of x-ray. Phil UK

Interesting comments, but has anybody actually had film damaged by putting it through check in baggage?

I used to religiously carry mine through until I got fed up. As a test, I tossed a few in my luggage for check in, came back the same way and I exposed them at home. All seemed fine. Film was colour Fuji or Kodak print film and Ilford XP2 and all no higher than 800asa. Now I just put unexposed and exposed film in check luggage. Perhaps something wrong with my vision? :confused:

Airports were UK and across Europe. Not tried the States or Far East.

I read somwhere that not all checked luggage is x-rayed. We've travelled with things like a lathe motor (with wires hanging out) and a full power saw kit complete with venomous-looking blades. Going into the country with the saw kit the x-ray operator said to me "you got coffee in that bag?". I did, but not a word from anyone about the saw...

There was someone here a few years ago who put the wrong bag into the hold flying back from a shoot in Las Vegas. A large proportion of the film was ruined.

Never. Some of mine has done aus bangkok laos laos domestic bangkok china mongolia cnina bangkok sydney in one trip, sydney new zealand, plenty of hongkong shanghai hongkong sydney in the hold and no problems at all.

There have been plenty of people showing up in the forums over the years blaming all manner of problems from light leaks to mass processing stipple roller marks on the xray.

The other good one is people refering to the written lit from Kodak that referred to cinema film reels returning from location that were worth Brad Pitt, cast, crew and location costs.

Time these xray questions went into the flouride in the water made my daughter pregnant folder.

There's damage and damage.

 

  1. Just enough fogging to be detectable by comparing the density of unexposed areas of films that have and have not been been x-rayed.
  2. Enough fogging to be just visible to the naked eye as increased density in the unexposed areas of the film (between frames, along the edges).
  3. Enough fogging to make a significant difference to print quality - which means quite a lot. With a high contrast image a bit of fog might even make it easier to print (same effect as the 'low contrast' lenses some people treasure.

Film manufacturers and serious cinematographers want less than (1), especially if the reels are worth tens of millions. Pro stills work wants less than (2). More than (3) spoils holiday snaps.

They will just turn up the x-ray strength until they can see into it...

 

A modern myth. The operators can put the film through the scanner multiple times but I don't believe they have any option to alter the strength of the x-ray.

Even if it is a modern myth, as soon as they see an impenetrable lump of solid metal on the scanner, you're in for an interesting half an hour that you could more usefully be spending in Costa Coffee or reading the Daily Mail in Smiths...

 

Coming back from Orlando a few years ago, my wife had a plastic bag with US coins in to hand in on the plane for charity. It showed up as a solid lump. We had all our hand baggage tipped out, I had the PoweBook swabbed for explosives, cameras, everything. Putting the coins in the bag in a tray would have avoided all of that and saved us time and them money. Give these people every opportunity to do their jib efficiently, and everyone is better off.
