I am a still photographer mainly for landscape, architecture & fine art (with an interest in urbex photography).
I am a director/cameraman mainly for corporate films.
I am currently based in Berlin, Germany.
The media's new holy grail of survival in the business is - currently(!) - the convergence of photo and video.
It seems that there's no other way other than every photographer shall become a film maker or vice versa.
Nobody mentions the key element, though.
Passion. True passion for what you do.
