Anyhow, I recently bought a roll of Superia 1600 online as it had been a while since I've shot it. It was expired 10/14 and quite expensive for an expired film (> $12). I was promised by the seller that the film was stored properly. I shot a roll of it at a concert and the images came out horribly. The grain was unacceptably high and the film looked underexposed. Developed 38.8C, 3.5M, fresh C41.
I shot a roll of Natura 1600 in mixed light from daylight to dusk, developed 38.8C, 4M, also very grainy and the color was poor. This was not expired.
I've been shooting Portra 800 @ 1600 and souping 3.5M-4.5M in C41 chemistry for years. The output is fantastic- fine grain, smooth tones, great color.
I'm just trying to figure out if I'm missing something or I've hit such a sweet spot with Portra that nothing else can be compared to..
Thank you.
Of course attempts to brighten underexposed film will exacerbate the grain.
I have only shot a handful of Fuji Natura 1600 and consider it's grain to be very manageable. Grain characteristics - like color, is personal preference so here are a couple of examples of what I consider manageable.
Very large file -> Fuji Natura 1600-02-19
Very large file -> Fuji Natura1600-03-31
I also consider the color palette of Natura to be neutral and latitude high.
I tend to favor Kodak's palette more so than Fuji's and really like Portra film - 160, 400 and 800. I have never pushed process 800 though. I wouldn't know what you consider a sweet spot as far as pushed process Portra 800 is concerned unless you have something to compare.
Here are a couple of examples I have from Kodak Portra 800 straight up.

Umm..Rodinal pre-treated CN film? Am I missing something?
I tried Superia 1600 a couple of times and found it to be too grainy for my taste. I like Rodinal pre-treated or pushed Portra 400 or even just underexposed Portra 400 better than the Superia 1600. Superia 800 isn't too bad. I just tried some Cinestill 800T and found that Portra 400 looks better to me at the same EI 800 in mixed light or daylight. Cinestill 800T looks pretty good in pure tungsten lighting though, but I haven't shot it enough to be sure I like it as well or better. There are plenty of examples posted on my Flickr account linked in my signature.
I am now pre-treating my EI 1600 Portra with 10 minutes of 1:100 Rodinal. I then process as C41 normaly. I had asked if something like this could work after reading some related posts online and Athiril came up with some recommended times for 1:100 at 10 minutes. It was right on the mark. It works to improve the appearance of the grain. There seems to be a slight shift in color toward green but not bad and I'm always in mixed lighting anyway. It may add a tiny bit of shadow detail in some cases as well. Here is a link to some examples on my Flickr account. https://www.flickr.com/photos/lamarlamb/sets/72157649126917440
I have two rolls of Portra 800 in the freezer to try at EI 3200 when football season kicks in.
My point with the Superia 1600 is that either a) the film lost speed due to age or improper storage or b) the film really isn't EI 1600.
