If you’re shooting traditional film for cameras, such as 35mm or 120 film, it is generally recommended NOT to put it through an X-ray machine at an airport. X-ray machines used for baggage screening can potentially damage undeveloped film or cause fogging, which can result in ruined or degraded images.
To protect your film from potential damage, it’s advisable to request a manual inspection instead. You can ask the TSA security personnel at the airport to hand-check your film. Be aware that they are not obligated to comply with your request, as their priority is security. However, in many cases, they are willing to accommodate such requests, especially if you explain the sensitivity of the film.
In case they deny a hand check, be sure to have a Domke film guard bag to protect your film from X-rays
It’s important to note that the guidelines and procedures regarding film screening can vary by country and airport. Therefore, it’s always a good idea to check the specific regulations and recommendations of the airport you will be departing from or arriving at, or contact the airline or relevant authorities for the most accurate and up-to-date information.
