OH, now I'm clearer on this...

This relatively fast, unexposed film was X-rayed 8 times prior to being
exposed.  That would place it at considerable risk of being damaged.

 Hand baggage, but it was checked about 8 times. I did not expose the
 film on the trip. I was exposed when I returned to Jamaica.

The last time I was in the states, about a year ago, I left from an
airport in Syracuse NY.  When I asked for hand inspection of my camera
bag and film, the two elderly gents, who looked like they were retired
FBI to me, said they wanted to have the equipment chemically sniffed. 
They took some pads of white clothlike disks, looking a bit like the
cotton cosmetic pads some use for makeup removal, and wiped down some of
the film canisters, the camera body, the bag, and parts of lenses.  They
then took these pads and placed them into some sort of device that
apparently sniffed these cloth disks for residue from nitrates or
other potential explosive components. 

Luckily, I'm not much one to get into fireworks of any kind, so I guess
my camera equipment was clean and they let me through.  They seemed to
enjoy playing with their toys, however, and I told them how much safer I
felt knowing they were being so careful.

 It may (or may not) be worth mentioning that smugglers have been using film
 canisters for quite some time. Occasionally, there's going to be an
 overzealous customs inspector, especially when you travel from country to
 country (and Norman listed 3 US Ports of Call--Miami, Puerto Rico, and The
 Virgin Islands). If he carries a Jamaican passport, that would make him an
 automatic suspect (albeit unfairly).  This doesn't deal with the problem at
 hand, though, which is the salvage of Norman's underwater pictures.

Norman,
  I curious, is the edge of the film (by the holes) darkened?  I'm making
the assumption that the photo-sensitive emulsion is even over the width of
the film, even the portion not normally exposed.  If the film edge is clear,
then overexposure is likely the problem.  If not, then xrays are the
culprit.

FWIW X-ray exposure is completely cumulative, there is no reciprocity

if below the baseline exposure required to produce any image at all.

Correct.

 Film must never be left in checked baggage these days, the X-ray machines
 they use for that are guaranteed to fog your film.

It's a pity they don't warn anyone!  Reminds me - when checking my luggage
in Hong Kong I was asked to look at the Xray machine and explain what one
of the items in my bag was; it was clearly a 35mm SLR.  Beats me why the
guy operating the machine couldn't tell!  Maybe nobody ever puts cameras
in their checkin luggage so it was unexpected.  At that point I was on my

home and the camera was empty.

Re: filmscanners: fogged film

2001-07-15 Thread Arthur Entlich

The FAA has a regulation for the US (which is also usually honored in
Canada) that is a traveler requests hand inspection of camera and
film, that the carry-on luggage X-Ray security person is supposed to
grant you your request.  That usually does not require opening the
camera back.

Sometime the person will try to ignore you request, but you can always
ask to speak to a supervisor, who usually know the regulation.

Keep in mind that most airport security people who run the X-ray
machines are hired by the airlines, and have minimal training, and since
the salaries aren't great, this is not usually a career position and
there is a lot of change over.  I found sometimes the employee is new
and unaware of the FAA ruling.  So be firm.

Most North American X-ray machines will do minimal to no fogging of low
ISO films, but the effect is cumulative, so if the film goes through
numerous machines it will get fogged even if it is a slower film.

Lastly, once again, do not put undeveloped film into checked in luggage
as the new machines they use on checked in luggage can do great damage
to unprocessed film.

 OK, this is only a side comment and suggestion, since I'm not a pro, but
 since the shots were gotten at considerable effort, I'd strongly consider
 having them duplicated before I did anything drastic. And that would
 probably mean Kingston, or even Miami.
 
 I'm surprised that there was X-ray fogging, unless the camera went through
 the machine with exposed film in it. I've only gotten X-ray fog once, and
 those were the circumstances. It didn't seem to affect the unexposed frames
 that remained in the canister. Since then, I either unload the film or keep
 the camera out of the X-ray machine. If they say they have to open the
 camera, then you'll wind the film back into the can, anyway...hopefully.

 Older machines in some airports are notoriously bad, but most current 
machines in  North American and European airports are new enough that
they should not create problems, even with multiple exposures.

I just scanned ahead and see you had 8-10 exposures and some were out 
of NA and you were using medium-high speed films.  This probably 
explains it.  I always request hand inspection.  The best way to do 
this is to use clear film canisters like Fuji supplies with the film 
out of box, obviously, and put them flat in a heavy clear zip-lock 
type bag, so they can see right through.  Usually they won't even both 
to open the canisters, although sometimes they will.

Now that the new X-Ray scanner is being used on checked in luggage, you 
have more reason to demand hand inspection, since you are really given 
no choice anymore (they used to tell me to put my film in checked in 
luggage...)

Is there enough visible image, Norman, that you can pull some of it out in

your point this way, or (with a heckuva lot of work), you may be able to 
reconstitute the colors to a semblance of what you saw while you were 
diving. This, unfortunately, will diminish the legal credibility of the 
photo (which any digital manipulation would do, anyway), but it might 
provide enough evidence to get a second documentary attempt started, or even 
financed.

I feel for you, man. That was a piece of really rotten luck. But I think the 
comments it elicited from the List members will give you a better shot on a 
second attempt, if you can manage it.

If the worst comes to the worst, duping onto slide stock may work, using

I'd guess this could make the problem worse since taking the photos was

 I imagine there would be more image surviving the experience if the Xrays
were overexposing film with an existing latent image?

Forget about the HP Photosmart, the way to do is with the Nikon and Vuescan, and
use the multiscan feature (experiment with number of passes). Output your files
in 48bit tif mode so that Photoshop has a chance of adjusting the levels..
expect some noise (grain) in the shadows. Adjust the brightness setting in
Vuescan until you get a decent looking histogram. Finalize all adjustments in
Photoshop.

I do astrophotography, every frame I take looks like what you describe (g)..

Urgh! You'd probably do best to use the LS2000 with Vuescan, multiscanning

If you do not use high ISO film you can let it through

NEVER leave film in checked baggage as some airports
have X-ray machines that can visibly damage it. The

Vuescan's settings are so cryptic that I couldn't suggest any concrete
numbers.  I would just suggest that after your initial Preview, you start
by increasing the Image brightness to 2 or 3 perhaps, try different Gamma
numbers, uncheck Auto black point and try 0 or some decimal (this I've
never needed to try), and even play with the White point number %.

The nice thing is that after each adjustment just click Prev Mem and
rather than a lengthy re-prescan the program will redo it's memorized
prescanned image and give you a quick result.
