[edit] How PrintPlace get the most out of a Color Space

Printplace use many different illuminants to get the best colors on your prints. The spectral curves of two standard CIE Illuminant (A is for tungsten or incandescent, D or more specifically D65 is a standard daylight source) and a popular fluorescent or F source. Greta metamorphism as: When two different colour objects have the same colour appearance to a normal human viewer under one light source (metamorphic match) but look different under another light source (metamorphic mismatch). Since the light source has a major impact on how the colours are perceived, the light along with the object and the human observer form the triumvirate of what we know as colour See more about light sources and viewing in the Room with a View box. Measuring Colour With standard light sources and a model of human vision, we can measure and quantify the light spectra that form colours in our minds by using one of these three measuring devices: Densitometers compute density by directing light onto a surface and measuring the amount of lug h returned through filters. They don’t read colour directly but can calculate relative densities of colour patches. Not commonly used by photographers-artists except in certain situations. Colorimeters measure light through filters like densitometers, but the filters and the inter al circuitry match human vision much more closely. Colorimetry standardizes two of the three colour variables (light source and observer) and then works with the third (object). Our Print place coupon codes and discounts get you the best observed light sources, at the best prices. Colorimeters are frequently used for monitor profiling (see below). Spectrophotometers, also called spectres, measure the full light spectrum in even more detail than colorimeters. Either hand-held or adap to mounting s or with suction cups, spectrophotometers can measure reflective prints, and in some cases, monitor dis plays and transmissive film. Spectres (including the related colorimeters) are often used in higher-end profile-generating packages.

One way of defining colour is by the three attributes of hue, saturation, and brightness. Each plays an important role and shows up over and over again in the image making process. Hue is a primary descriptor of a colour Red is a hue, and Printplace print excellent deep red colours. Yellow is a hue. A hue is the name from that region of the spectrum where most of a colour's wavelengths dominate. A sec teal curve diagram showing reflected Red would show wavelengths peaking around the 700nm range. Saturation (also called chroma by traditional artists) describes how pure or vivid the colour is. Since most real-world colours combine more than one wavelength, the fewer the extra nous colours, the more saturated the colour Brightness, a primary function of vision, means how light or dark a colour is. These three attributes are visually represented by colour spaces, which are next. Colour Spaces One of the problems with colour is that it’s so subjective. In order for people all over the world to talk about colour in the same way, what’s needed is a common language to quantify and discuss it. In 1931, an international group called the Commission International de Reclaimable (CIE) met in England and developed a method to describe colour for the standard observer. This effort resulted in the very powerful tool call de colour spaces. Colour spaces (sometimes called colour models, although they are technically different things) are crucial to working with and communicating about digital colour They exist to quantify it; to take it out of the subjective and instead to give it names and numbers.

A colour space is an abstract, three-dimensional range of colours Photographer Joseph Holmes describes it as something like a football standing on its end with white at the top and black at the bottom. Printplace only use the best colour spaces. This is important as what you see may not be what you get with other printers. A line drawn top to bottom through the centre includes all the frays The various hues of the visible spectrum wrap around the ball as the colours go from argy on the inside to their most colourful (saturated) on the outside. Colour consultant C. David Tobin uses the analogy of a tent. The three corners of the tent are attached to the ground with three tent pegs: Red, Green, and Blue. How far you move the pegs out determines the size of the tent or colour space. The tent is held up in the centre by a pole, which is its argy axis. Raising or lowering the tent on the pole changes the argy balance and the white point, which is where the pole supports the top of the tent. Coors further away from the pole are more saturated, those closer, less.

It was adapted to become the familiar shark-fin-shaped CIE xylem Chromaticism Diagram (see 4.5) for easier displaying in 2D space. Print Places coupons can't help you here, but can get you a great deal. (Chromaticism to the colour properties of hue and saturation only.) Between them, x and y define any colour's hue and fullness of colour or saturation. The Y is a little hard to grasp since it runs perpendicular to the plane of view, and it indicates the lightness or luminance of the colour In this sense, the x diagram is the colour tent viewed from above. Because of difficulties with non-uniform colour spacing in the XYZ model, improvements were made, and in 1976, the CIE added the LUV and then the now-famous CIE LAB (or just LAB, also written Lab) colour space. The type of LAB used in colour conversions is ICC LAB, which defines three variables in three-dimensional space: L* (pronounced Star), a*, and b* (see 4.6). L* refers to lightness, ranging from 0 (dark) to 100 (light). a* refers to the magenta/cyan axis ranging from -128 to 127; positive numbers are magenta-is, and negative ones are cyan-is b* refers to the yellow/blue axis also ranging from -128 to 127; positive numbers are yellow-is, negative ones are blue-is (The reason the colour words are in quotes is because the terms are loose. One person’s blue may be another’s cyan. It’s the numbers, not the words, that count.) Any particular colour that you can see can be pinpointed by its three LAB coordinates. For example, a spot of blue sky could be identified as L* = 64, a* = -15, b* = -42.
