Introduction to Photography STILL PHOTOGRAPHY Course Descriptions The department of Photography at the IFT offers a provocative and experimental curriculum in the setting of a large, diversified university. As one of the pioneers programs of graduate and undergraduate study in photography in the India , we aim at providing the best to our students to help them relate practical studies in art & craft in professional context. The Photography program combines the teaching of craft, history, and contemporary ideas with the critical examination of conventional forms of art making. The curriculum at IFT is designed to give students the technical training and aesthetic awareness to develop a strong individual expression as an artist. The faculty represents a broad range of interests and aesthetics, with course offerings often reflecting their individual passions and concerns. In this fundamental course, students will identify basic photographic tools and their intended purposes, including the proper use of various camera systems, light meters and film selection. -
Zone System Definitions
Zone System Definitions These definitions are meant to be used as guidelines for placement of shadow and highlight values using the Zone System of exposure. They can be used as a starting point for previsualization of a scene with a variety of black and white films, developers and papers. Materials vary in their tonal scale and latitude. For proper control of the Zone System a photographer should test each film and paper to be used. Zone VIII Areas falling in this zone will be white with almost no texture; sometimes referred to as photographic paper white. Only small areas should be allowed to fall this high, such as spectral highlights. Zone VII This is the highest value which will hold texture and detail with most films/developer combinations. It should be used for areas such as: white clothing, white paint and snow in sunlight. All films are more sensitive to blue light. Blue areas of a scene (such as skies) that fall in this zone will be very dense on the negative and rendered white on a print. Zone VI This value is generally used for light skin tones, sky values and concrete sidewalks in direct sunlight. Zone V This zone is known as 18% grey, middle or grey-card grey. This is the resulting value when an area is read and exposed as indicated by all reflective light meters. This value is generally used for dark skin tones Zone IV This value is usually used for average dark foliage, large well-lit architectural shadows, and shadow areas in light skin tones. -

Exposure Metering and Zone System Calibration
Exposure Metering Relating Subject Lighting to Film Exposure By Jeff Conrad A photographic exposure meter measures subject lighting and indicates camera settings that nominally result in the best exposure of the film. The meter calibration establishes the relationship between subject lighting and those camera settings; the photographer’s skill and metering technique determine whether the camera settings ultimately produce a satisfactory image. Historically, the “best” exposure was determined subjectively by examining many photographs of different types of scenes with different lighting levels. Common practice was to use wide-angle averaging reflected-light meters, and it was found that setting the calibration to render the average of scene luminance as a medium tone resulted in the “best” exposure for many situations. Current calibration standards continue that practice, although wide-angle average metering largely has given way to other metering tech- niques. In most cases, an incident-light meter will cause a medium tone to be rendered as a medium tone, and a reflected-light meter will cause whatever is metered to be rendered as a medium tone. What constitutes a “medium tone” depends on many factors, including film processing, image postprocessing, and, when appropriate, the printing process. More often than not, a “medium tone” will not exactly match the original medium tone in the subject. In many cases, an exact match isn’t necessary—unless the original subject is available for direct comparison, the viewer of the image will be none the wiser. It’s often stated that meters are “calibrated to an 18% reflectance,” usually without much thought given to what the statement means. -
Computational RYB Color Model and Its Applications
IIEEJ Transactions on Image Electronics and Visual Computing Vol.5 No.2 (2017) -- Special Issue on Application-Based Image Processing Technologies -- Computational RYB Color Model and its Applications Junichi SUGITA† (Member), Tokiichiro TAKAHASHI†† (Member) †Tokyo Healthcare University, ††Tokyo Denki University/UEI Research <Summary> The red-yellow-blue (RYB) color model is a subtractive model based on pigment color mixing and is widely used in art education. In the RYB color model, red, yellow, and blue are defined as the primary colors. In this study, we apply this model to computers by formulating a conversion between the red-green-blue (RGB) and RYB color spaces. In addition, we present a class of compositing methods in the RYB color space. Moreover, we prescribe the appropriate uses of these compo- siting methods in different situations. By using RYB color compositing, paint-like compositing can be easily achieved. We also verified the effectiveness of our proposed method by using several experiments and demonstrated its application on the basis of RYB color compositing.

The color yellow is primarily associated with spreading happiness and joy, however, it is also the ideal color for symbolizing friendship. Fall color can also be assisted by late planting of some species. Any number of complementary pairs can be determined simply by shifting positions on the color wheel, but for the purposes of planning flower-color combinations, designers usually confine their discussions to the primary and secondary colors.

However, understanding the basic principles of using color in design can help make that picture in your head a reality. This article covers the basics on using color in your garden bed.

OSHER Color 2021
OSHER Color 2021 Presentation 1 Mysteries of Color Color Foundation Q: Why is color? A: Color is a perception that arises from the responses of our visual systems to light in the environment. We probably have evolved with color vision to help us in finding good food and healthy mates. One of the fundamental truths about color that's important to understand is that color is something we humans impose on the world. The world isn't colored; we just see it that way. A reasonable working definition of color is that it's our human response to different wavelengths of light. The color isn't really in the light: We create the color as a response to that light Remember: The different wavelengths of light aren't really colored; they're simply waves of electromagnetic energy with a known length and a known amount of energy. OSHER Color 2021 It's our perceptual system that gives them the attribute of color. Our eyes contain two types of sensors -- rods and cones -- that are sensitive to light. The rods are essentially monochromatic, they contribute to peripheral vision and allow us to see in relatively dark conditions, but they don't contribute to color vision. (You've probably noticed that on a dark night, even though you can see shapes and movement, you see very little color.) The sensation of color comes from the second set of photoreceptors in our eyes -- the cones. We have 3 different types of cones cones are sensitive to light of long wavelength, medium wavelength, and short wavelength. -
