400VC vs. 400UC
Is it correct to say the difference between 400VC to 400UC is similar to the difference between tri-x and tmax 400, in terms of grain? I love tri-x over tmax 400.
I know 400UC is newer. more saturated color. What are other differences?
The small amount of shooting I have done with these two films, the biggest difference I have noticed is the color saturation, I have not noticed much difference in the grain structure.

Of course, I could be wrong.
There are three "suffixes" for Kodak print films: NC, VC, UC. They mean more or less: Normal, Very and Ultra. The C is meant to be either Colour (saturation) or Contrast: two adjacent areas of different hues but of matched values have a higher contrast at high saturation than at low saturation.
There are two categories of speed: slow (160 or 100) and fast (400 or 800). That gives the following combinations
160: NC, VC
400: NC, VC, UC
800: no suffix, but I suppose it's got to be like NC
All of these films use T-grain technology, the same you find in T-Max. The 800 was upgraded recently, so it might have some newer tech in it. So all of these are colour T-Maxes, not coulour Tri-Xes. I have no idea if Kodak or anyone else still produces colour film using conventional grains.
Using film since before it was hip.

I haven't used much 400VC, but I use 400UC all the time. My experience is that the grain is similar between the two, but 400VC is a bit more contrasty and 400UC is more saturated. 400UC changed recently and became even more saturated. I think they overdid it.

After the last wedding I did, I would have to agree, I found myself a bit short on what I normally carry to shoot a wedding and have always shot Fuji, and the local shop had 400UC in stock and no fuji at all, I am telling you, compared to the fuji I used, the UC was REALLY saturated...would make a great fall color print film..
