FOR THE TECHNICALLY MINDED...
I use fairly ordinary cameras and most of the recent street photographs were taken with a compact camera the Panasonic Lumix LX3 which has a lovely little Leica f2, 24 -60 mm zoom lens, which I have used since June 2010. I often use the generic Dynamic Black & White mode - in camera - so I can view the scene in B&W before I take the shot.
Quite a few images were also captured on two Nikon Coolpix Cameras, the P5100 and the E5700. I also used a DSLR Nikon D80. My current *DSLR Camera is a Nikon D300 which I use with Nikon 85mm f1.8 D lens; Nikon 50mm f1.4 D lens;Nikon 24mm f2.8 D lens and a Sigma 18-50mm f2.8
All the shots taken with the D80 & D300 cameras were originated in colour. Some later converted into Black & White using image editing software on my laptop.
Most of my early film work, was taken on a variety of 35mm cameras - mostly those such as the Canon A1; Canon A-E1; Canon T90 and other smaller Range-finder style 35mm Cameras. All used Manual Focus Canon Lenses, ranging from 28mm to 300mm.
Since 2012 I'm also usinga Fuji X100 which has a fixed 23mm f2 lens (equivalent to 35mm in full-frame terms). a great little camera for Street & Low Light Trad Photographs.
Some earlier Studio and Landscape work I used a Kowa Super 66 (aka 6cmx6cm square) with standard and portrait lenses.
The 1980s trad photos on this site were taken on film - mostly 35mm and shot in Black & White using Ilford HP5 Film and Kodak Tri-X. Conventional chemical development.
* DSLR means a Digital Single Lens Reflex camera -one that is put direct to the eye, while twisting the lens barrel (in manual mode) to achieve focus. It also has a mirror system which lifts up when the shutter is released, to record the image on the light sensitive electronic sensor behind it.
