Traditional Photography is based on the subtractive Colour synthesis model
Equipment Taking pictures
Cameras (bodies) Lenses Lightmeters Flashguns Motordrives Gadgets (tripods, filters, bags, close-up equipment
Developing pictures Darkroom ( dry and wet equipment) Developing tanks, spools Enlargers ( lenses)
‘Even the most sophisticated camera is just a light-tight box’
Exposure of image on film via light-source Balance of amount of light for a given time Sensitivity of film ( ASA / ISO 100 = standard Amount of light (aperture) Time (shutter speed) Each combination of aperture and shutter speed for a
given film speed ( sensitivity) has a particular exposure value (EV)
Lighting Available light On-camera flash (usually gives red-eye) Off camera flash - diffuse lighting via bouncing Studio flash - multi-flash setup
Traditional v Digital Traditional
larger range currently available less expensive high-end equipment need to support legacy stock image libraries
Digital more accessible by novice users professional equipment very expensive still needs to improve resolution for high quality production
requirements
Developing & Printing (D&P) Darkroom (wet-side)
developing (developer, colour developer, fixing, stablizing, washing)
Darkroom (dry-side) Contact sheets Enlarging image onto photographic paper Producing prints from slides Improving image by ‘dodging’ and ‘burning’ areas of the
image ( like Photoshop)
