RGB is a standard for color space, a representational form for displaying color. There are two standards of RGB, the sRGB and the Adobe RGB. The two standards differ in terms of the range that the color space can recreate.
This is the RGB color space standard prescribed by the International Electrotechnical Commission (IEC). It is an international standard adopted by general software and hardware such as Windows®, displays, printers, and digital cameras. By using sRGB-compatible devices for input and output, color differences can be minimized even between differing devices to re-create the desired color. However, the range of colors that can be expressed is somewhat limited.
- Adobe RGB
This is a standard proposed by Adobe Systems. It has a broader reproduction area range than sRGB, so it can express colors in more detail. It is widely used in areas such as the printing industry.
NOTE: In order to correctly output Adobe RGB color as an image, a compatible software and a compatible hardware such as displays and printers are needed. Images recorded in Adobe RGB will result to a low saturation image if the TV, monitor or printer is not compatible with the Adobe RGB standard (DCF2.0/Exif2.21). It is recommended to record using sRGB if a compatible software or a hardware is not available.
