After shooting digital professionally for nearly 20 years, I am just about done with it. I use it for about 8 weeks a year for some ad and corporate work with a D800 / D4. The main thrust of my work now is black and white fine art printed by hand in a real darkroom. I use 6x6, a 6x12 back on a Chamonix 45N-2 and 4x5 with the same camera, the resulting prints simply blow away anything I see from a computer print. The camera, 5 lenses, 12 film holders, a host of filters, step up rings all fit into a Lowe Pro Flipside Sport 15L AW and with a full camelbak and a carbon fiber tripod, it tips the scales at just over 21 pounds.
Scaling back digital in favor of film for fine art is the best career move I have ever made, I am doing really well in terms of income and could not be happier shooting large format film and not sitting in front of a darn computer.
So yeah, you could say I use large format...
