Re: filmscanners: fogged film
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. Art Norman Quinn wrote: No just the film. This is the 1st time I have had fogged film too. Did the film travel as hand baggage, or in hold luggage? Hand baggage, but it was checked about 8 times.

Re: filmscanners: fogged film
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.

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. Dave

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 way home and the camera was empty.

Re: filmscanners: fogged film
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.

Norman Quinn 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 BlackWhite, using Lab or RGB colors? You *might* be able to demonstrate 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.

I'd guess this could make the problem worse since taking the photos was trying to add an image to a film that was already exposed by the Xrays. I imagine there would be more image surviving the experience if the Xrays were overexposing film with an existing latent image? Anyone with more knowledge of chemistry care to comment?

Re: filmscanners: fogged film
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)..

Re: filmscanners: fogged film
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.
