Too expensive for mediocre results
Since this is a specialty film it makes sense that this film is expensive, but in my opinion this film is not worth the price for the final product. This film has an unflattering green tint that is moderately annoying to remove in post. The film cannot handle any underexposure without creating a muddy green tint to the entire image, so meter for the shadows or overexpose the film by one stop for usable results. If you want a low speed ISO film, just expose Portra 160 at 80 ISO since it will produce a much more pleasing result compared to CineStill 50D.
Very impressed with the results
There are some color corrections you will need to do, the film does produce more of a green tint. I shoot with a Hasselblad 500cm, and will probably use a daylight color correction filter next time to see if that lessens the green tint. A little color correction and it’s fine. I very much enjoyed the results this film produced. Make sure you have PLENTY of light. 50 speed film can be challenging if you shoot later in the afternoon. I meter typically for the shadows to retain that detail, which produced very good results for me.
