i am a beginner enthusiast. along with digital, i've recently been experimenting with negative film (color and b&w). for color film, i am overwhelmed and confused by the plethora of product lines under just one film brand - kodak. i'm sure fuji has an equally dizzying array of names. my question is: is there an appreciable difference between these myriad kodak color negative film brands? is the 'professional' moniker applied to portra meaningful? so far, i have tried only gold (200) and max (400), and just one roll of each. but i believe there are other names, such as supra, and perhaps more...? what i'm trying to understand is how to choose: is there a catch-all approach, or do serious photographers simply try all and ascertain for themselves what works best for their work? thank you very much for any and all insights and guidance. vikram.
