I have never really looked into black and white photography but after recently purchasing a Sony A6000 mirror-less camera I have come out with shots I feel quite happy with as a first timer, and humans as a subject in my pictures are not my strong suit.
I have found that black and white images look to be more timeless than a colour image does, I have found in doing my images in colour without the use of photo shop does not catch the emotional state of the subject and its surroundings. Black and white portraiture lets the audience see your subjects face and emotions.
As humans most of us see the world in colour but using the black and white makes us look more closely at it, I have always photographed in colour because the images I take are of landscapes, food photography which benefit from warm deep colours and contrasting tones.
The cameras that you can purchase these days mostly do all of the jobs that a cameraman needs the hardest thing is to find the right subject at the right time, so make sure you always carry that camera with you, as you never know what is around the corner.
My best buddy and mentor through the early days of my chefing career, Deene Randall was happy to stand for me in some shots in his work place, The Bell at Burton Overy http://www.thebellburtonovery.co.uk/ alongside his wife and also my great friend Sarah Randall, who makes exceedingly great puddings.
