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

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.

Linear ProPhoto RGB color space introduction

Also known as the Linear 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.
Linear ProPhoto RGB is a variant of the ProPhoto RGB color space, where the nonlinear gamma curve typically applied in ProPhoto RGB is removed.
Linear ProPhoto RGB or ProPhoto RGB Linear.
In Linear ProPhoto RGB color space, colors are represented through Red (R), Green (G), and Blue (B) channels without gamma correction.
Linear ProPhoto RGB is primarily used in image processing tasks that require linear calculations, such as image compositing and high dynamic range imaging.
Due to its provision of direct linear light values, Linear ProPhoto RGB is particularly suited for advanced image editing tasks that require precise color control and extended dynamic range.
