What is the difference between AdobeRGB and sRGB, and how to choose a camera?

Adobe RGB and sRGB are two different color spaces. SRGB is a widely used standard color space, which is dominated by companies such as Microsoft and Hewlett-Packard. Its color gamut covers a wide range, including colors that are not completely covered in the sRGB color space, which can more truly restore the color of the subject. Adobe RGB is a practical color space proposed by Adobe Company in 1998. It is suitable for simulating printing colors, with wider color gamut and higher color saturation, and is suitable for professional designers and photographers.

In sRGB color space, color representation is determined by the values of three color channels: red, green and blue. Among them, the value range of red channel is 0-255, the value range of green channel is 0-255, and the value range of blue channel is 0-255. In Adobe RGB color space, color representation is determined by the values of four color channels: red, green, blue and yellow. Among them, the value range of red channel is 0-255, the value range of green channel is 0-255, the value range of blue channel is 0-255, and the value range of yellow channel is 0-255.

In addition, Adobe RGB covers a wider range of colors, including colors that are not available in the sRGB color space, such as yellow, magenta and cyan. This makes Adobe RGB have more freedom in image processing and editing, and can better restore color details and transitions. SRGB is more suitable for users who browse on the network platform or have less demand for color management.
