I think its pretty obvious that I'm a Velvia 50 nut. I really don't have much experience with anything else. I dont know how to develop BW films, but I process my own E6 slides at home once a month.. I just havent bothered to learn other films really.
Colour is the main thing I shoot for. Obviously composition is key and intereting details help, but for me if a photograph is vividly coloured and has a good set of colours throughout the image its a good image, as such, I have always shot Velvia 50 and on occasion, velvia 100..
I would like to learn about colour negative films for the times where I need a few extra stops of latitude, but as yet have not heard of a film that is colourful enough for me whilst giving more than 5 or 6 stops of range appart from velvia which when exposed carefully can give around 6 stops.
So the question is: What film do you shoot most and why.
