I really like the look & feel of the videoclip "Love Story" by Taylor Swift.
Can this be done with MB Looks or how do you think this can be achieved ?

I saw this clip on a bad TV at the gym, so forgive any mistakes on my part, but it looks like it was shot on film. The color grading (low saturation, sepia tone) was probably done afterwards. It can certainly be done with filters in cam, but the look was so consistant, I suspect it was applied afterwards.

There's no reason that you couldn't approximate this look using Magic Bullet. It will be hard to duplicate the dynamic range of film, but you can get close with careful lighting.

Arri 435 and a set of Arri Master Primes.
