View Camera
8 x 104 x 5 Camera is usually referred to by the size of film
Twins Lens Reflex TLR
Rangefinder Camera
Viewfinder Camera
Single Lens reflex camera
SLR
Focal Plane Shutter
Leaf Shutter
Found in most film and digital SLR Cameras.
Reading the light meter
Shutter Speed
1/30 of a second 1/500 of a second
Panning
1/30 of a second
Shutter Speeds
Using the shutter Speed to express Movement.
The Aperture acts like an iris
The Aperture controls amount of light entering the Camera and the Depth of Field
Aperture Controls the Depth of Field
Depth of Field - Area of the picture that is in focus
Depth of FieldArea in the picture that is in focus
Controlled by distance from subject
Controlled by Distance
Controlled by Aperture
Depth of FieldControlled by the focal length size (type) of lens
A given type of film always needs an exact amount of light for a proper exposure.
As a photographer you determine the way the film receives the light by combining fstops and shutter speedsto give the picture the effect you want.
Combining Shutter Speed and Aperture for desired effect
Time andTemperature
Greatly affectthe results when developing a negative
Full Tonal Range
MeteringA light meter always wants to give you an average reading or
middle grey.
Backlighting
Take the meter reading from the subject

Polarizing Filter and the sky
Mid day 90° to the sun
Subtractive Color - determined by the reflection of light waves to the eye
Mixing paint pigments is a subtractive color system
Each secondary color is composed of equal amounts of adjacent primary
colors. G + R = YR + B = MG + B = C
Each color is complementary to the color opposite.
Primary colors of light
Additive Colour R G B
In 1666, Isaac Newton passed a beam of sunlight through a glass prism breaking it into a rainbow of colors that form the visible spectrum. He then passed the rainbow through a second prism converting the colors back into white light.
When light is refracted each wavelength is bent to a different degree separating the light into different bands of color.
It is the wavelength of light that determines
its color.
Colour is determined by the lighttemperature.
Film must be balanced for the light source or coloured filtersmust be used to achieve realistic colour.
Daylight film is balanced for5500 K
Indoor film or tungsten colour film is balanced for 3400 K type A or 3200 K type B
Time of day determinescolour and drama of image.
Sunrise One hour later
Midday, sunny Midday, overcast Late afternoon
Tungsten Film
Daylight Film
Daylight/daylight film
Tungsten/Tungsten film
Daylight/Tungsten film
Tungsten/Daylight film

Use FL-D /daylight film
Use FL-B /tungsten film
Florescent light is very difficult to balance, as currently there are many types offl. bulbs on the market. Turn off all fluorescents whenever possible !
Old fashioned, standardflorescent bulbs.
