At subzero temperatures, emulsions stiffen and leader tips crack. Carry film close to your body, and advance slowly to avoid tears. Mechanical shutters may slow; compensate with exposure notes. When gloves numb, pause rather than rush. Treat the camera like a companion, not a tool to be forced.
Moving from icy air into warm huts fogs optics and risks moisture inside bodies. Seal gear in a bag before entering, letting temperature equalize gradually. Resist the urge to peek. With patience, glass clears cleanly, and you avoid moisture spots that spoil highlights you worked so carefully to protect.
Request hand checks politely and arrive early. Explain that high-speed film can fog under strong X-rays, especially after multiple scans. Use clear pouches and keep rolls unboxed for quick inspection. A calm smile, labels, and respect for staff usually shepherd your images safely toward the darkroom they deserve.
