Type of processing, like c-41 is a type of processing (chemistry). I 
may have to go back and check the letters (CN) but I think this is 
it. There may also be another letter after the N, such as K, like CNK 
-4. I can look it up - have the book.

You don't have to compensate for tungsten balance, but its better 
that you do. Dale for years asked you to identify the light source 
(for 5247) and filter when you sent the film in for processing. Like, 
"daylight", "flash", "halogen lights", and compensating filter. And, 
they processed the film accordingly, compensating for the color 
temperature of the exposure. But, most people never checked those 
boxes, and the slides/prints came out fine. Go figure.

The thicker negative is not harder to scan. Actually holds in the 
negative holder better than thinner film. And yes, I scan a lot of 
it. Also stuffs far more easily into archive pages than store bought 
film strips. Because of the added rigidity.
