## Film Reciprocity Reviews in United States

### *---- "wrong calculations"
portra 400 is wrong. Its based off the correct chart, but the math is really incorrect. I would be wary of trying to use anything else on this app if the calculations off a basic chart are this off. Theres another app that has the correct calculations, but not this one!

### ***** "works!"
Does exactly what it says it does. Very easy to use.
