Slide1Principles of LightThe Science Behind Photography

Slide21. White light ismade up of equal amounts of  red , blue  and  green light.

Slide31. White light is made up of equalamounts of  red ,  blue  and  green  light. additive process subtractive process

Slide41. White light is made up of equalamounts of  red ,  blue  and  green  light. • Red, Blue and Green • Cannot be made • Exist in Nature • PRIMARY COLORS RED GREEN BLUE WHITE

Slide51. White light is made up of equalamounts of  red ,  blue  and  green  light. RED GREEN BLUE WHITE MAGENTA YELLOW CYAN

Slide61. White light is made up of equalamounts of  red ,  blue  and  green  light. • Cyan, Magenta, Yellow • Combine EQUAL amounts of 2 PRIMARY colors • SECONDARY COLORS RED GREEN BLUE WHITE MAGENTA YELLOW CYAN

Slide71. White light is made up of equal amounts of red ,  blue  and  green  light. • Wavelengths of color are viewed on the spectrum. • Visible Spectrum = Rainbow Water acts like a PRISM to REFRACT or BREAK APART white light into all colors

Slide81. White light is made up of equalamounts of  red ,  blue  and  green  light. Cameras  can  see infrared and ultraviolet but we  cannot .

Slide91. White light is made up of equalamounts of  red ,  blue  and  green  light.

Slide102. Objects get their colorfrom reflected light. • All colored objects reflect light to some degree. • White objects reflect all the light that hits them. • Can only take a photograph when there is a light source. • No light = No color

Slide112. Objects get their color from reflected light.

Slide122. Objects get their color from reflected light.Can you change the color of an object by changing the light source?

Slide132. Objects get their color from reflected light.You can  change the color of an object by changing the light source!

Slide143. Black objects absorb all light.• Black is not a color • It is the absence of color • Black objects absorb ALL the light that hits them • Inside if cameras, darkroom, developing tanks are black • WHY?

Slide15Can you see this?

Slide163. Black objects absorb all light.Can a camera see black? Can black be photographed? Will the film be exposed?

Slide173. Black objects absorb all light.Camera  cannot  see black? Black  cannot  be photographed? The film  will not  be exposed?

Slide184. Silver, when struck bylight, turns black. • Silver is the main ingredient in film/ photo paper because it is sensitive to light. • Silverware and jewelry tarnishes.

Slide194. Silver, when struck bylight, turns black. • Film/photo paper has two main layers: • Emulsion • Base • Emulsion – silver particles suspended in a gel • Base – support for the emulsion; paper or plastic

Slide204. Silver, when struck bylight, turns black. • Emulsion – silver particles suspended in a gel • Base – support for the emulsion; paper or plastic EMULSION BASE

Slide214. Silver, when struck bylight, turns black. EMULSION BASE

Slide225. Light travels in astraight path. • Light travels in wavelengths.

Slide235. Light travels in astraight path.

Slide245. Light travels in astraight path. • Images are recorded on film upside down and reversed. • We see the same way.

Slide255. Light travels in astraight path.

Slide265. Light travels in a straight path.

Slide275. Light travels in a straight path.• Larger lens opening, more light, blurry image • Smaller lens opening, less light, sharper image Pupils dilated by eye doctor? Squint eyes to see better?
