Spectral Power Distribution to CIELAB, Visual Density and sRGB
This tool allows you to convert from SPD values to CIELAB, visual density and sRGB.
It is very useful to calculate the visual density through low-cost spectrophotometers as X-RITE ColorMunki
You can only use the following ranges of values, separated by commas:
- 410-730nm in 33 steps1
- 380-730nm in 36 steps2
1This range is common of applications such as Spotread of ArgyllCMS
2 This range is common of applications and tools of X-Rite as ColorMunki or Photo ColorPicker
The spectral values must be expressed in hundredths. If you are using ArgyllCMS you need activate the option '/100'
