Response to Alternative to Xtol

Daniel, even if you make fun of me: Physical methods to alter the toe of the rendition curve of films have been effective strategies often used by professional photographers, because -- different from pushing -- they do not have any negative side effects, such as increased grain and contrast. This was particularly true decades ago when films were used for press work that are today considered as medium speed. There is no difference in which way you create the additional latent fogging: Radiation is radiation, if visible (light) or invisible (Xray, gamma, neutrons etc.) The power plant will work off course, if you can get close enough to the rods, but I fear that calibration will be the problem and it might affect your hair in a rather adverse way. The nice thing about the airport security system seems a high degree of repeatability if you checked it out once and calibrated your "system" of run throughs. I was totally serious about this. Since I had some films left over from the trip I off course used them with the higher film speed. But this experience also showed me, that there is always some effect of airport Xray on the film, even if you do not see it on the developed film. From then on I insisted on manual checks when I transported exposed material.
