I’m not sure why, but the scans from this roll of Portra 400 are extremely grainy. The film wasn’t underexposed, and I’ve done nothing unusual in my scanning process, so I’m uncertain as to the cause. I wonder if the high heat might have had an effect? Or maybe the airport scanners (although I’ve had no issues with taking Portra 400 through an airport in the past)

If you’ve done nothing different, perhaps the variable is in your lab’s chemistry or processing? I tend to get small variations like this when my C-41 chemistry is nearing the end of it’s usefulness and I have to mix up more.
(Just a thought; I also start with my own process as the likely culprit because it usually is…)

Yeah, I tend to look to myself as the first cause of problems too on the premise that, if something can go wrong, I’ll probably find a way to do it at some point. 😉
