The chart shows the WB presets including the amber/blue compensation on the Kelvin temperature scale with examples of different light sources' colour temperature.

Please note that the amber/blue compensation values, are based on Nikon's statement in the D300 manual, that compensating 1 step (e.g. from a1 to a2) changes the colour temperature with 5 Mired, and not any actual measurement from my side. I have also decided not to show a linear Kelvin scale, but rather made entries for common light sources.

I have printed the chart and laminated it, and always have it with me in my photo bags. Feel free to download the chart and use it as you wish.
