In fact, it's the de facto default color space for (like printer) and color-aware application (photo editor) can handle images Just about every scanner and digital camera can produce One overwhelmingly important characteristic: it's the most commonly-usedĬolor space. The most commonly-used color space is called “sRGB,” which has Range of encodable real-world frequencies and amplitudes are converted to
That can be encoded, and the mathematical parameters for how the smooth Maximum frequency that can be encoded, the range of amplitudes (volume) Space” would be a set of parameters such as the minimum and Using music files as an analogy, the “sound Interleaving.”) and a color space describes how to interpret the Of pixels arranged this-and-that way, using such-and-such compression and (“such-and-such metadata is allowed, the image is composed of lines You can think ofĪ file format as being a standard for how to arrange image data Have the ability to use different color spaces - different ways toĮncode the image color - for their raw numeric data.
Many image file formats (such as JPEG, TIFF, DNG, etc.) To be clear, the concept of a color space is different from aįile format. The technical details areĭiscussed later in the article for the moment, just consider them Different color spaces meanĭifferent conversions: different real-world colors from the same number, orĭifferent numbers from the same real-world color. So, a color space is a set of parameters that describe how to convertīetween numbers and real-world colors. Here's an example (me and my son, neither of whom are supposed to be green!): The result is an image with wrong colors, like a TV whose Know how to properly recreate the color when printing or displaying the Numeric color data (and if it isn't able to guess correctly), it doesn't Numbers in an image file if an application processing an image fileĭoesn't know which scale was used in creating the image's raw There are actually many different ways to represent color with Numeric data - data that is not “color,” but numbers When it comes to representing color, the digital-image version of this kind Number, but also the scale in which to interpret it. “65” in meters/second is a category-4 hurricane,Īnd “65” in Mach is faster than a meteor.Ĭlearly, when discussing speed, it's important to know not only the raw Speeding ticket, while “65” in kilometers/hour is only half In miles/hour is highway cruising speed, but “65” in knots on the highway is a
There are multiple ways to interpret a number as a speed: “65” 7 This is the first page of a seven-page article
