Cones: Photoreceptors in the retina of the human eye that are sensitive to high light levels. The eyes have three sets of cones, each sensitive to a portion of the visible color spectrumred light, green light and blue light.

 


-Cones - sensory organs on the retina of the eye, allowing color vision.
-Constructivism - art movement that begun in Russia c. 1913. Characterized by the use of everyday materials in abstract compositions.

We experience color by means of two kinds of sensors in the retina of our eye: These are known as rods and cones. The former ensure vision at lower levels of illumination, while the latter account for higher light levels and the color that we see.

The first thing that should become obvious from looking at Figure 2 is that the cones are not equally sensitive to all colors.

It is purpose built for the job, including four different lens cones ranging from 90mm to 250mm. These cones are rigid, as opposed to flexible bellows which can cause vibrations.

Flower petals and pinecones are two examples of spiral designs that use the Golden Ratio. Why this ratio of 1.618?

Our retina is build with rods and cones. Rods offer much better night vision, but far less color sensitivity than cones. Since our eyes have to keep a fixed exposure time, this is nature’s elegant trade off.

The other kind of cells, cones are responsible for color vision. There are three subtypes of cones, the difference between them being the wavelength selectivity, or primary color for which they are tuned.

Look out for distracting backgrounds (such as a marshal’s bright overalls or road cones). A backgrounds, however, can enhance the shot, such as a grandstand of spectators that turns into a colourful blur in a panning shot.

Note that the cones in our eyes see this reflected light in RGB mode. An object appears Red because Green and Blue have been absorbed. Since the combination of Green and Blue is Cyan, Cyan is absorbed when you add Red.

Finally, don't be afraid to jazz up your digital productions with shots of trip mementos (a basket full of pine cones from Flagstaff) or insert copies of postcards that you bought and then scanned into your computer.

Common redpolls, pine grosbeaks, purple finches and evening grosbeaks all come to bird-feeding stations. Bohemian waxwings descend on mountain ash and crabapple trees. White-winged and red crossbills flock to spruce and pinecones.

Children eating ice cream cones have been done a million times. Think of something original. Show a subject in a new way.
Action is good.
