    fyi. Some of you may have read about the new CT machines being installed in airports - Beware: New 3D Airport Scanners Will Wipe Unprocessed Camera Film. This development should be of great concern to those trying to get film through airport security checkpoints because the new machines will unequivocally ruin photographic films of all kinds whereas the older machines used to scan carry-on items were relatively safe, certainly for slower films (I can report from personal experience that on my travels abroad, I put film thought carry-on x-ray inspection as many as 8 times without adverse effects). Everyone knows the machines used to scan checked luggage are far more intense and that films will not survive that examination without sustaining some serious damage - which is why we always carry film through vs. having it checked through. Immediately after the first of these stories about the new, higher-energy machines for scanning carry-on items came out, I contacted both Analog, the maker of the new machines, and TSA to ask what effect, if any, these new x-ray machines might have on light meters. Below is the response from TSA that I received today. (As an aside, for those who may think sending film home via mail is a sure-fire way around this problem, I would urge you to do some research first, because everything I have read on that topic indicates that USPS packages are also subjected to x-ray scanning. I do not know whether those scans are yet strong enough to ruin film.)

    Here is the reply fromTSA:

    "Good Afternoon,
    We appreciate your recent inquiry through the Transportation Security Administration (TSA) Contact Center (TCC) regarding Computed Tomography (CT) scanners and photographic film.
    TSA does not have information on the effects that CT scanners have on the calibration or function of light meters in photographic film. Due to high sensitivity of undeveloped film and possible camera light meter issues, TSA recommends having film and cameras with light meters hand-inspected by a Transportation Security Officer to prevent possible damage.
    If you require further information, please contact the TCC for assistance.

    Thank you,
