Chapter 1 & 2 Notes (Light: Science & Magic)

How to Learn Lighting
- "a photographer without mastery of lighting is like a Shakespeare who could only speak the language of the people in the Globe Theater Pit"
- lighting = language (texture, feel, meaning)
- principles ~ predict behavior
-- size of light
-- types of reflections
-- family of angles
A photographer who understands lighting can execute any style
- successful photographs come from the photographer- not the equipment
- shooting digitally helps to get a better sense of instant feedback
- camera clubs are a good source of info

-know the basics of photoshop in post editing
-shoot in RAW
- it can be impossible to have enough equipment for the perfect lighting
- it is possible to have enough equipment to photograph well 
- the sun can be your "equipment"
- small scenes = little light
- lots of information and help on the Internet

Light: The Raw Material of Photography
-we are more interested in the manipulation of energy than matter
-presenting light to a viewer
-electromagnetic radiation : weightless group of photons
-electromagnetic field : changes as photons travel
- some are faster than others
-  the difference in photon energy is seen as color
- rate of fluctuation = frequency
- some cameras can see a larger range than the human eye
- describing light needs to be possible in order to control it
-brighter = better
- smaller aperture or faster shutter speed (if they have more light already)
- color is a mix of primary colors (red, blue, green)
- color temperature scale : if we heat material in a vacuum, it will glow a color)
- color temperature is measured in Kelvin - K
- 5500°K = daylight
- 3200°K an 3400° = standard
- hard shadow : sharply defined edges
- hard light : high contrast light sources
- soft shadow : no clearly defined edge
- soft light : light producing it
- size = primary influence
-shadow : part of scene that light does not strike
- highlight : area illuminated 
- lighting = relationship between light, subject, and viewer
- transmission : light that passes through a subject
- refraction : bending of light rays 
- direct transmission : light passes through in a predictable path
