Sepia toning, etc would class as mono whereas black and white is exactly what it says.

Mono is an abbreviation of 'monochrome', the definition of which is:

"paintings, drawings, design, or photographs in one color or shades of one color. A monochromatic object or image has colors in shades of limitedcolours or hues"

from Wikipedia.

I always thought Mono (Monochrome) was the same as black and white and without colour. As per the above definition, Monochrome is where the inage contains , shades of of one colour. Black and White is where there are two colours, black and white, and all the other colours are "shades of grey", not being totally black or white but in-between. I suppose you could argue that a high contrast B&W is in fact black and white, but low contrast, i.e shades of grey is monochrome

So, for those old enough to remember...Were we watching The Black & White Minstrel Show in black & white or in mono?

The fact that they have to be defined separately clearly indicates they are not the same thing. Mono means one, black and white = two.

Ok so this is what wikpedia say and by the sounds of it are still a little confusing as it states Monochrome is one colour yet it is classified as being Black and white so how is that?

Monochrome
From Wikipedia, the free encyclopedia
For other uses, see Monochrome (disambiguation).


A photograph rendered with a monochrome palette of a limited number of shades
Monochrome[1] describes paintings, drawings, design, or photographs in one color or shades of one color.[2] A monochromatic object or image has colors in shades of limited colors or hues.[clarification needed] Images using only shades of grey (with or without black and/or white) are called grayscale or black-and-white. However, scientifically speaking, "Monochromatic light" refers to light of a narrow frequency.

[edit]Application

For an image, the term monochrome is usually taken to mean the same as black and white or, more likely, grayscale, but may also be used to refer to other combinations containing only tones of a single color, such as green-and-white or green-and-black. It may also refer to sepia displaying tones from light tan to dark brown or cyanotype (“blueprint”) images, and early photographic methods such as daguerreotypes, ambrotypes, and tintypes, each of which may be used to produce a monochromatic image.
In computing, monochrome has two meanings:
it may mean having only one color which is either on or off,
allowing shades of that color, although this is more correctly known as grayscale.
A monochrome computer display is able to display only a single color, often green, amber, red or white, and often also shades of that color.
In film photography, monochrome is typically the use of black-and-white film. Originally, all photography was done in monochrome until the invention of color film plates in the early 20th century.


Monochrome anaglyph image stereogram rendered in red and cyan
3D red cyan glasses are recommended to view this image correctly.
In digital photography, monochrome is the capture of only shades of black by the sensor, or by post-processing a color image to present only the perceived brightness by combining the values of multiple channels (usually red, blue, and green). The weighting of individual channels may be selected to achieve a desired artistic effect – if only the red channel is selected by the weighting then the effect will be similar to that of using a red filter on panchromatic film. If the red channel is eliminated and the green and blue combined then the effect will be similar to that of Orthochromatic film or the use of a cyan filter on panchromatic film. The selection of weighting thus allows a wide range of artistic expression in the final monochromatic image.
For production of an anaglyph image the original color stereogram source may first be reduced to monochrome in order to simplify the rendering of the image. This is sometimes required in cases where a color image would render in a confusing manner given the colors and patterns present in the source image and the selection filters used (typically red and its complement, cyan). [3]
[edit]Theory

In physics, monochromatic refers to electromagnetic radiation of a single frequency. In the physical sense, no source of electromagnetic radiation is purely monochromatic, since that would require a wave of infinite duration as a consequence of the Fourier transform's localization property (cf. spectral coherence). Even very controlled sources such as lasers operate in a range of frequencies (known as the spectral linewidth). In practice, filtered light, diffraction grating separated light and laser light are all routinely referred to as monochromatic. Often light sources can be compared and one be labeled as “more monochromatic” (in a similar usage as monodispersity). And a device which isolates light sources of a narrow bandwidth are called monochromators, even though the bandwidth is often explicitly specified, and thus a collection of frequencies is understood.
