Light Balancing Filters (LB: usually used for warming/cooling or tungsten/daylight shifts) or Color Correction Filters (CC: usually used for magenta-green shifts) can be used on lens to correct for subtle color temperature shifts in your light source, or to correct for more drastic imbalances of film/camera color temperatures to the light source.  For example, if you are shooting outside under daylight color temperatures with tungsten balanced film, you could use an 85B filter on lens to warm the daylight to more closely match the tungsten film's color temperature.  CC filters are typically used when it is critical to balance the color temperature of a light source to the film.  For example, still life photographers would use a color meter to help figure out what CC filters would balance the light for accurate color results in the products they were shooting.

(LB) Light Balancing Filters

Color correction gels, such as CTB and CTO, "Color Temperature Blue", and "Color Temperature Orange" are larger sheets of gels that are put over light sources to alter or "correct" the color temperature of a light to more closely match the color temperature of a film negative, or chrome, or the white balance of a digital camera.

These gels can also be used in a creative way!  Use over your speedlight flash to add color and mood to the background as in the example below:




To be shot in teams of 2 in class:
  
Shot Outside:
  1. Daylight shot with WB @ 3200˚, + 85B LB filter over lens (as if you were using Tungsten film outside with a correcting LB filter for daylight use)

Shot Outside:
  1. Daylight shot with WB @ 5000˚K (or Daylight Preset)
  2. Daylight shot with WB @ 3200˚K (or Tungsten Preset)
  3. Daylight shot with WB @ 3200˚K, shot down -2 stops
  4. Daylight shot with WB @ 3200˚K, speedlight reading +2 from camera setting (still at -2 so FG is proper exposure, but BG is -2)
  5. Daylight shot with WB @ 3200˚K, speedlight +2 (or more) with Full CTO on strobe  

  Shot Inside:

  1. Fluorescent shot with WB @ 5000˚K
  2. Fluorescent shot with WB @ Fluorescent preset
  3. Fluorescent shot with WB @ Fluorescent preset and Speedlight +1

A3: Color Temperature




Assigned: Week #4 2/2211
Due Date: Week #6 3/7/11

Images Due:  8 Digital Images
Details:  Set your digital camera to Daylight White Balance Preset or Manually to 5000-5500˚K, Raw image capture, and a color profile of Adobe RGB.  If you retouch, also provide the unretouched file!

For this assignment, you are going to explore color temperatures using your digital camera as your tool. 

Part A - Color Temperatures (edited to 4 final shots):
I would like you to shoot subjects of your choice (people, landscapes, still lifes, etc.) illuminated by light sources that each have their own unique color temperatures. Shoot multiple images lit by different types of light sources such as fluorescent, tungsten, floodlamp, neon, mercury or sodium vapor (streetlights), etc.  *Explore subjects illuminated by multiple light sources in the same shot to further understand the concepts of white balance.
Keep in mind that you should be shooting outdoors at night, dusk, dawn, or indoors in order to have a majority of your scene illuminated by artificial sources.  Therefore, I highly recommend shooting with a high ISO (so your image sensor is more sensitive to the light) and using a tripod (because you may be shooting with very slow shutter speeds!).

Part B - Time of Day (edited to 4 final shots):
To further illustrate the concepts of color temperature, you are going to shoot your subject illuminated during specific times of the day.  To more accurately demonstrate light and color changes, shoot outside with only daylight on a relatively clear day(s) at sunrise and/or sunset  (6:41am and 5:39pm).  Start on this as soon as you can, because if you wait until the last minute, I’m sure the weather will stink and your grade will reflect your results!


*The Catch!...
To add a bit of creativity to this concept you will be exploring a simple “divergence test”. Divergence tests are best for measuring one’s imagination.  You will attempt to take your mind in as many different directions as possible to conceptually solve the assignment. Bottom line: Divergence tests are a great measurement of creativity.
            Here’s your assignment:  Write down as many uses as possible that you can think of for a brick and then a blanket.  There are no wrong answers, but be creative as possible.  Then, illustrate these concepts utilizing the lighting guidelines of Part A and Part B above.  You may use all brick answers, or brick ideas for Part A only, or 2 brick ideas for each Part A and B, or… it is up to you.  Be creative and have fun!

Submit all 8 digital files (at least!) in class week #6 labeled appropriately.
Example File Naming = “A3_Name_A_Tungsten.CR2” or “A3_Name_B_6:30am.CR2”



Week #4: 2/22/12 Perceptual Color + HSL

The difficulty with color is to go beyond the fact that it's color – to have it be not just a colorful picture but really be a picture about something. It's difficult. So often color gets caught up in color, and it becomes merely decorative. Some photographers use [ it ] brilliantly to make visual statements combining color and content; otherwise it is empty. - Mary Ellen Mark, “Mary Ellen Mark: 25 Years” by Marianne Fulton, ISBN: 0821218387, Page: 5

Munsell Color System
 Color consists of 3 basic elements: 

Hue (or color) - valued between 0˚ and 360˚
Saturation (or chroma) - vividness or purity of a color valued from 0 to 100
Luminance (or lightness/brightness) - lightness or darkness in a color valued from 0 to 100




Perceptual Color 

We see colors in relationship to other colors in our field of vision. 
The appearance of any one color is modified by the presence of other colors.

Two colors, side by side, interact with one another and change our perception accordingly. The effect of this interaction is called simultaneous contrast.

Lightness shift:  By far the best example of simultaneous contrast since value dominates our visual experience.  Want to make a color appear lighter? Make it lighter or make surrounding colors darker.

Lightness Shift
 
Saturation shift:  The next strongest visual effect.  Want to make a color appear more saturated? Make it more saturated or make surrounding colors less saturated.

Saturation Shift

Hue shift:  Want to make a color appear cooler? Make it cooler or make surrounding colors warmer.

Hue Shift

Week #3: 2/15/11 Technical Color

“..Why would anyone want to photograph an indisputably colourful world in monochrome? If colour film had been invented first, would anybody even contemplate photographing in black and white?” - Russell Miller , Magnum: Fifty Years at the Front Line of History by Russell Miller , ISBN: 0802116310 , Page: 4

Color Temperature and White Balance 

The color temperature of a light source is measured in degrees Kelvin and it describes its color exactly.  The lower the color temperature, the more “warm” red wavelengths are in the light.  Higher color temperatures have more “cool” blue wavelengths.


Cool = above 5500˚K (like shade at 6000˚K) 
Neutral = 5000-5500˚K (like midday daylight)
Warm = Below 5000˚K (like Tungsten at 3200˚K)    

In a digital camera, white balance is a setting that compensates for the differences in color temperature of the surrounding light. The white balance must be adjusted to ensure that all colors in the scene will be represented faithfully. It can be adjusted automatically by the camera or manually, by selecting presets (tungsten, fluorescent, etc.), or by aiming the lens at a totally white surface (the white card) and selecting "lock white balance." Alternatively, a gray card with 18% gray is sometimes used and can be clicked on in post-production (processing a RAW file or using a color adjustment such as Curves in Photoshop) to adjust the white balance to a neutral point.

White Balance Presets and Color Temperature Scale 

Shot with Manual White Balance Settings.  Notice it's the opposite of what you would think - 3000˚K is Cool - It's more like adding a color filter to adjust for the color temperature the camera thinks it is capturing!

Week #2: 2/8/11 Color as Emotion

Black and white photography is a perfect lie. We must not let colour destroy this image. - Patrick Summerfield

One very important difference between color and monochromatic photography is this: in black and white you suggest; in color you state. Much can be implied by suggestion, but statement demands certainty… absolute certainty. - Paul Outerbridge - [Julia Scully, “Seeing pictures”, Modern Photography, Oct. 1976, p. 8]

Additive Color - In class review
 
In class we also explored how 3 flashes (each with respective red, green, and blue filters affixed to them) when popped independent of each other produced all the other colors we can see.  Some results are below.  Also notice how the subtractive primaries are produced in the shadows when shot on a white background.  This results when the blue shadow, for instance, is filled with both the red and green flashes - thus illustrating that when red and green light mix, we do indeed produce yellow light.








Red flash, Green flash, and Blue flash shadows produce the subtractive primaries CMY
