Re-cap of techniques

Camera issues that may relate to shooting photojournalism.

Camera formats commonly used in analogue (film)
-35mm
-120 roll film
-4"x5" sheet film

35mm equivalent in digital would be a canon 1D, 5D or Nikon D700 etc.

To achieve minimal depth of field:
-focal length.
eg long lenses (135mm etc) telephoto lenses.
-aperture stop
eg f1.4, low as possible
-file format.
as large as possible -4"x5", even though the lowest f stop is 5.
-minimize subject distance.
bring the subject closer to the lens.


To increase the brightness, aperture should go up as the shutter goes down. If you increase the ISO it increases the brightness even more.
ISO is a measure of sensibility. ISO 1 would be very slow to react to light - for things that aren't going to move and the lighting isn't going to change.
Originally 35mm film ISO only went to about 25, whereas some of the top digital cameras now go to 51200. Although the higher in ISO you go the grainier your pictures are going to be come. It adds a lot of noise.

Prime lenses are very useful for photojournalism.
Wide, Normal and Telephoto. Its said the restriction of a prime lens is better for creativity.

Shooting modes.
M- setting aperture and shutter speed
Av-set the aperture and the camera sets the shutter (most important for depth of field control)
Tv-you set the shutter and the camera sets the aperture
P-the camera sets both

Visual Principles
-juxta position (putting something in front of something else)
-decisive moment
-visual irony
-viewer recognition (recognition, detail, meaning)
-composition (could be a cinematic scene)
-symbol inclusion
