Evolution of the Camera

First camera: “pinhole camera” or camera obscura;

  • developed by Aristotle;
  • drawing tool
  • black box with tiny hole
  • temporary capturing of an image before invention of photographic paper
  • *****smaller pinhole, better the detail (need longer exposure time because less light)

-REVOLUTIONARY MOMENT: when mirrors and lenses went into pinhole camera

-mirrors not developed until Scientific Revolution

First picture recorded: Silver Gelatin (film print) black and white print by Niepce, 1824

The First Photograph

-photographers/scientists created an emulsion (chemical surface that’s light sensitive) that they would put on a silver plate and expose . . . (did not know how to stop developing from happening)

. . . finally figured it out in 1839; Daguerre discovered chemicals needed to stop developing process and fix; prints called “daguerrotypes”-one of a kind images done on a silver plate

-1st negative-glass negative called Callodine Wet-Plate Process

  • 1850’s-when photography was not for the masses
  • negative was the negative and photograph
  • had to develop immediately; could not store emulsion
  • process used in the Civil War

-Photography can have a bias. Based on how a photographer chooses to take their picture, they are impacting the viewer.

Stereographic Photograph

  • 1870’s

-invention of the “disposable camera

  • George Eastman invented film; where emulsion could be stored and dried; did not have to develop immediately
  • 1888
  • $25, 100 frames
  • person would send camera back, Eastman-Kodak cameras would develop film and send it back
  • HUGE IMPACT: photography now for the masses; artists now use photography as a use of art; more impressionism in painting

Photo Students on a 5-Day tour of National Parks in the South West

Building on what we have learned this year, photo students set out on an adventure to the South West.  With the help of a student impact grant from the CHSN PTSA, landscape photographer Michael Malandra provided workshops and hands on experience both before and during the trip.

Stay tuned for an exhibit of work after our post editing sessions with Mike.

 

Studio Lighting

Studio Lighting

Types of Light

1. Continuous Light (stays on)

  • Example: sun, room lighting, light bulbs
  • All have different qualities to them – not all made equally
  • Type of light you experience with the sun is different than the light experienced with fluorescent lights
  • The different types of continuous lighting emit different types of light that are different colors
  • Example: Taking a picture inside with light bulbs around and the pictures come out yellow-ish/orange

On digital cameras you can find this under WB (white balance)

~different types of light emit different colors

  • Example: Sun, light bulb, cloud
  • Direct/Natural Sunlight (SUN) -downside of this is shadows.
  • Incandescent/Tungsten Bulb: Literally hot, makes warm tones in your photos (BULB)
  • Flourescent: Makes cool tones (SCHOOL LIGHTS)
  • Diffused Light: Overcast (CLOUDS)
  • Diffused light is the best lighting scenario: all the tones stay even and you can achieve whites

2. Strobe Lighting (Burst of Light)

  • Camera Flash (ON Camera Strobe)
  • Strobe Light (OFF Camera Strobe/Flash)
  • Strobe Light HAS to sync with your camera
  • Replaces the shutter speed, do not have to set shutter speed
  • Still have to set the F-STOP, using higher ones such as 16 and 22, to get a large DOF, and so that the strobe light doesn’t overexpose the subject we are looking at
  • Strobe Light has a reserve, just as the camera flash does, after using it it needs to recycle the energy again
  • Strobe Light connects to the camera where the flash typically does at the hot shoe
  • If we have two lights, we want them to fire at the same time, both lights communicate and shoot at the same time
  • Flash on the camera can also sync with the strobe light

Direction of Light

  • LIGHT TRAVELS IN STRAIGHT LINES!!!!
  • When doing a shoot, you are making decisions about the distance of light, angle of light, and the height of the light
  • You can control the path!

1. Light Behind the Subject = Silhouette

2. One Light on One Side = Strong directional shadows; moody/artistic

3. Two Lights at Same Angle and Height = MOST COMMON FOR PORTRAITS/ minimize shadows

  • 45 degree angle
  • Eye level
  • Standard Portraits

There are two lights inside:

  1. Coil Light – Strobe
  2. Modeling Light – Continuous
  • Allows us to be totally in control of all the light in the room
  • You need a light on to set up the shoot

Strobe Light Vocabulary

  1. Modeling Light: Continuous light source in the strobe light, used for setting up the shoot and focusing
  2. Synch Cord: Connects the light source (flash) to the camera
  3. Hot Shoe: Synch cord gets plugged into the hot shoe, a mount that sits on the top of the camera, used to connect flashes or synch cord
  4. Slave: Enables you to use multiple lights, part of the strobe light that allows you to fire multiple lights and have them communicate
  5. Ambient Light – Available Light

Power: Big red button with thunderbolt above it

Modeling Light: Gray button with light bulb above it (continuous light source)

Slave: Eye above it, to turn on the slave feature

Test/Recycle: Smaller red button used to recycle the energy in your flash, you can use just to test if the flash is working

Output Dial: You can turn up the power of light

Reflector Umbrella: Diffuses the light and spreads the light evenly for a well-lit picture

  1. Silver Umbrella: Harsher/Stronger Light
  2. White Umbrella: Softer Light
