ProPhoto RGB to LABh(hunter-lab,hlab) 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.

LABh(hunter-lab,hlab) color space introduction

Also known as the LABh(hunter-lab,hlab) color space.There are 3 channels in total,lightness,range from 0 to 100.a,range from -128 to 128.b,range from -128 to 128.
Developed by Richard S. Hunter in the 1940s as a color scale based on opponent-color theory. It is an adaptation of the CIE XYZ color space to be more perceptually linear.
Often referred to as Hunter Lab, or Lab Hunter.
Colors in the Hunter Lab color space are expressed through three coordinates: L (for lightness), a (red/green value), and b (blue/yellow value). These are calculated from CIE XYZ using Hunter's specific equations.
Hunter Lab is used in various industries for color matching, quality control, and other applications where a perceptually linear space is beneficial for color difference measurement.
Although similar to CIELAB, the Hunter Lab color space is used less frequently in contemporary applications. However, it remains significant in industries that adopted it early on and continue to rely on its specific color-rendering properties.
