Response to Splotches on Infrared 5x4 film

Having processed a ton of 4x5 ir sheet film using every method known to man, I'd say this is definately a processing problem. Did you use gloves to load this film? Left upper corner looks like finger smudges. Are you sure you used the correct processing techniques for tray development? This looks like bad agitation technique. If the problem was shooting through leafless tree branches the image would have been much more discreet. IR has a tendency to lightpipe when a lot of elements like leaves and branches are in the way. But they are usually defined much better. I'd opt for some other processing method with IR sheets. Let us know your next outcome. James
