Recently - oh happiness of happiness! - I received a beta roll of Cinestill 800T in medium format. I had been itching to get my hands on some ever since I first heard about the kickstarter; considering how much I enjoy the 35mm version, I couldn't wait to see how it performed in a larger format.  I had never used my Hasselblad at night without a flash, and was keen to have that experience.  And, having heard some people question why we as film photographers need 800T in the first place, since we already have Portra 800, I decided to compare the two.  The Portra was also new to me, so I was pretty excited about the whole thing,
