ProPhoto RGB to LAB(cielab) Converter - Color Space Converter

ProPhoto RGB color space introduction

Also known as the ProPhoto RGB color space.There are 3 channels in total, Red,range from 0 to 1.Green,range from 0 to 1.Blue,range from 0 to 1.
ProPhoto RGB, also known as ROMM RGB (Reference Output Medium Metric), was developed by Kodak. It offers an exceptionally wide gamut, designed for use in professional photography to ensure reproducibility of most colors found in nature.
ProPhoto RGB color space.
In the ProPhoto RGB color space, colors are represented through Red (R), Green (G), and Blue (B) channels, with a gamut much wider than traditional sRGB.
ProPhoto RGB is primarily used in the field of professional photography, particularly suitable for processing images with high dynamic range and wide color gamut.
Due to its vast gamut, ProPhoto RGB is especially suited for high-end image processing and printing tasks that require extreme color fidelity.

LAB(cielab) color space introduction

Also known as the LAB(cielab) color space.There are 3 channels in total,lightness,range from 0 to 100.a,range from -100 to 100.b,range from -100 to 100.
Defined by the International Commission on Illumination (CIE) in 1976, as an improvement and extension of the CIE XYZ color space, designed to be a closer approximation to human visual non-linearity.
Commonly known as CIELAB color space, abbreviated as L*a*b* or Lab.
Lab colors are typically represented by three coordinates: L* for lightness, a* for green to red chromaticity, and b* for blue to yellow chromaticity. They can be algorithmically converted to other color spaces for display or printing on different devices.
The Lab color space is extensively used in color measurement and management, particularly important in fields requiring precise color matching and assessment such as digital printing, photography, image analysis, and industrial color testing.
The advantage of the Lab color space lies in its device independence, allowing for consistent and accurate color conversion across different devices and software.
