My local camera store always has Lomography film in stock and I was surprised to see they had a new 800 speed color negative film in medium format. I've been shooting with Lomography 800 Color for a few months now and it's been something that has really surprised me.
Lomography 800 Color is a really great value. At only 6$ a roll it's an affordable film that gives you a much needed higher ISO for shooting with slower lenses. I reach for 800 speed film when I'm shooting in situations that I'm unsure how great the lighting scenarios will be. In the winter and fall this is pretty much anywhere outside and indoors in Texas.
During the summer and spring months it is also a great tool for shooting with toy cameras like the Diana and Holga. The extra stop of ISO gives you a little wiggle room for clouds and shadows. Spending a few extra dollars a roll for more exposure gives me a lot of peace of mind when developing my film too, and I'd gladly take a slightly overexposed shot than losing a shot or details to underexposure.
I was also surprised with the look of Lomography 800 Color. While Lomography has a reputation for giving images that looks like expired film I found Lomography 800 Color to be a wonderful performer. It gives you a slightly warmer tone and the emulsion constantly gives you brilliant oranges and yellows. Color rendition is accurate and never loud, it's less saturated than Ektar but doesn't lose anything in accuracy or detail either.
At the end of the day Lomography 800 Color is my second favorite color film, Kodak Ektar 100 being first, it's the 120 color film that I use the most because it's versatility allows me to shoot with more cameras and in more situations. I'll admit it's not the greatest color film in medium format but it's found a permanent spot in my current film rotation.
