Infrared
Photography

Notable Scientists or Engineers
Sir Frederick William Herschel
, a German-born British astronomer, discovered infrared light on 11th February in 1800.

Robert Williams Wood
is credited with the discovery of infrared photography when he sensitized his own photographic plates and produced the first known infrared photographs of various scenes.

Many artists in the 1960s also used Infrared photography on their cover albums (ex; Jimi Hendrix and Frank Zappa).

What is Infrared Photography?
Infrared Photography is light sensitive film that can capture pictures in infrared and ultraviolet lighting.
1911
1914
1919
1930
Ernest Rutherford Discovers the
Structure of an Atom
The Mona Lisa is stolen
The Chinese Revolution
When WWI started, IR photography proved extremely valuable, as images using the IR spectrum were not affected as much by atmospheric haze as normal photos. IR images were also able to show stark distinctions between vegetation and buildings, better identifying potential enemy targets such as camouflaged munitions factories and other key sites.
World War 1 ends
Pluto is discovered.
Infrared Photography was invented in
1910
when an American physicist named Robert Williams Wood sensitized his own photographic plates and produced the first known infrared photographs of various scenes. In 1930, Kodak developed emulsions that were sensitive to infrared light, and ever since then, Infrared photography has been improving.
The Optics behind Infrared Photography
The Infrared light spectrum (IR) refers to the spectrum of light just beyond the range humans can detect with their eyesight. This light range is between 700-1200 nanometers.
Infrared photography is therefore a certain type of film that can detect or see infrared light - which humans or regular film can't.

How It's Useful
Infrared light is just beyond our visible spectrum.

Not only is Infrared Photography be beautiful and open up a whole new world of photography ideas and designs, but it has a more serious purpose which normal film cannot do. One of the most important applications of infrared photography is taking snaps in a dark room, or of wildlife during the night. It's also used to capture images during the state of war, where light availability is reduced during the night time.
In the infrared image, the heat from the hand can travel through the bag and can be seen by an infrared camera. Infrared light can pass through many materials which visible light cannot pass through.
"Regular Photography" (digital or film) captures the LIGHT.
About
What equipment do we have?
We have Holga cameras you can check out that can take infrared 120 film. Ms. Rapp has to load and unload the film.

We also have two 35 mm film cameras that you can check out.

You must submit a proposal prior to checking out, as film is expensive.
Tips & Tricks
The Proposal
Teacher Examples
All images copyright 2017 by Melanie Rapp of Artiste Photography
Student Work
Requirements
* This project is a partial project, meaning you must work on another project in class.

* All images must be taken outside of school, and must be meaningful.

* Completed and approved proposal.

* Images must follow one or two themes.
* Using a red filter gives you more dramatic results. However, having the filter on the lens makes it extremely difficult to see your image. I hit auto-focus first, and then shield my eyes so I can see the composition.

* Bright sunny days work best.

* People look strange. If this is your intent, go for it.

* Normally I want all students to shoot on manual mode. However, since this is film, and film is expensive, shoot on aperture priority.
Email Ms. Rapp with the following information:

1. The
film
you would like to use.

2. Your
concept
. Specifically, what is your theme? What subjects? Where? When? Why?

3.
Pinky promise
Ms. Rapp that you will not take "selfies," "duck-face" photos of friends, etc with the film. Cross your heart and tell her that you will do your best to take meaningful photos and that you will give it your all with your compositions.

4. What project are you working on this week?
Fun Infrared Stop Motion!
Teacher Samples: Denver Botanic Gardens
I shot this roll of film with a red filter. This creates more contrast, as well as a really dark sky. The down side is that it is hard to see your composition. It's best to shoot outside, in bright light.
You may have to find a piece of your subject in the frame, and do your best to compose your photo.
When the film is scanned, it often has dust and fuzz on it. If you want to enlarge your image bigger than a 5x7, it needs to be professionally scanned. I use Mike's Camera in Park Meadows. The scans vary by cost depending on the size of file you need.
See the really dark sky? This is because of the red filter on the lens.
If you can't see to compose and focus, you can take the filter off. HOWEVER, put it in a safe place! The filter costs $60 to replace!
The lens on our camera works best for portraits and close ups (not landscapes). Next year I hope to buy more lenses.
