Black and white vs color photography essay

Positioning of subject elements to create contrast gives them added emphasis and directs the viewer's attention. When we speak of contrast as it relates to composition, we are referring to both tonal contrast, as in black-and-white photography, and color contrast as it relates to color photography.

Early experiments[ edit ] Colour photography was attempted beginning in the s. Early experiments were directed at finding a "chameleon substance" which would assume the colour of the light falling on it.

Some encouraging early results, typically obtained by projecting a solar spectrum directly onto the sensitive surface, seemed to promise eventual success, but the comparatively dim image formed in a camera required exposures lasting for hours or even days.

The quality and range of the colour was sometimes severely limited mainly to primary colours, as in the chemically complicated "Hillotype" process invented by American daguerreotypist Levi Hill around Other experimenters, such as Edmond Becquerelachieved better results but could find no way to prevent the colours from quickly fading when the images were exposed to light for viewing.

Over the following several decades, renewed experiments along these lines periodically raised hopes and then dashed them, yielding nothing of practical value.

An entirely different approach to color[ edit ] Gabriel Lippmann is remembered as the inventor of a method for reproducing colors by photography, based on the interference phenomenon, which earned him the Nobel Prize in Physics for On 2 Februaryhe announced to the Academy of Sciences: He presented his theory of color photography using the interference method in two papers to the academy, one inthe other in The named colors are somewhat arbitrary divisions imposed on the continuous spectrum of visible light, and the theory is not an entirely accurate description of cone sensitivity.

Why Color Matters

But the simple description of these three colors coincides enough with the sensations experienced Black and white vs color photography essay the eye that when these three colors are used the three cones types are adequately and unequally stimulated to form the illusion of various intermediate wavelengths of light.

During the lecture, which was about physics and physiology, not photography, Maxwell commented on the inadequacy of the results and the need for a photographic material more sensitive to red and green light. A century later, historians were mystified by the reproduction of any red at all, because the photographic process used by Sutton was for all practical purposes totally insensitive to red light and only marginally sensitive to green.

Inresearchers found that many red dyes also reflect ultraviolet light, coincidentally transmitted by Sutton's red filter, and surmised that the three images were probably due to ultra-violet, blue-green and blue wavelengths, rather than to red, green and blue.

Why Black and White Photography?

If one of these displays is examined with a sufficiently strong magnifier, it will be seen that each pixel is actually composed of red, green and blue sub-pixels which blend at normal viewing distances, reproducing a wide range of colors as well as white and shades of gray.

This is also known as the RGB color model. Subtractive color[ edit ] The same three images taken through red, green and blue filters which are used for additive color synthesis may also be used to produce color prints and transparencies by the subtractive method, in which colors are subtracted from white light by dyes or pigments.

In photography, the dye colors are normally cyan, a greenish-blue which absorbs red; magenta, a purplish-pink which absorbs green; and yellow, which absorbs blue. The red-filtered image is used to create a cyan dye image, the green-filtered image to create a magenta dye image, and the blue-filtered image to create a yellow dye image.

When the three dye images are superimposed they form a complete color image. This is also known as the CMYK color model. The "K" is a black component normally added in ink-jet and other mechanical printing processes to compensate for the imperfections of the colored inks used, which ideally should absorb or transmit various parts of the spectrum but not reflect any color, and to improve image definition.

At first it may seem that each image ought to be printed in the color of the filter used in making it, but by following any given color through the process the reason for printing in complementary colors should become apparent.

A red object, for example, will be very pale in the red-filtered image but very dark in the other two images, so the result will be an area with just a trace of cyan, absorbing just a bit of red light, but a large amount of magenta and yellow, which together absorb most of the green and blue light, leaving mainly red light to be reflected back from the white paper in the case of a print, or transmitted through a clear support in the case of a transparency.

Before the technical innovations of the years tothe only way to create a subtractive full-color print or transparency was by means of one of several labor-intensive and time-consuming procedures. Most commonly, three pigment images were first created separately by the so-called carbon process and then carefully combined in register.

Sometimes, related processes were used to make three gelatin matrices which were dyed and assembled or used to transfer the three dye images into a single layer of gelatin coated on a final support.The black and white setting for the Hewlett Packard LaserJet CP is located on the Color tab of the preferences menu.

When to Use Color

bluebird coloring page. Color vs black and white photography - A photograph's impact on a viewer can be aided or hindered by the choice of using black and white versus color. I find black easier on the eyes with high contrast black and white photos, but instead of white fading into the background I now have black fading into the background.

It's an interesting effect, but let's say I want to explicitly show the edges of the photo. For example for my Hanoi street photography project, I experimented with both color and black and white in the beginning, but then I decided while living and shooting in Hanoi for about a year that I preferred black and white.
