About

To use the Burn Checker Plus, click on the macro name in the Library. A layer is created called 'Burn Checker'. Double click on this to open it. It is a Procedural Texture adjustment. Just ignore the calculations near the top.

To explore RGB colours which are burned (reached their maximum), set 'Show Lights?' to 1. Pixels affected are inverted so you can see them, so those which are burned to white are shown as black, while yellow pixels are blue (the inverse of yellow). To explore RGB colours which are zero (reached their minimum), set 'Show Lights?' to 1. Here, a pixel which is red has the red value at zero.

You can also adjust Lights Limit and Darks Limit sliders to stretch the zone being selected. This is useful for exploring areas of the image which are near 1 or 0. This is useful when you are going to adjust colours such that they might bump against the maximum and minimum end-stops.

The other macro, 'Burn Checker to Mask' can be clicked after using the Burn Checker to turn the areas which have changed colour into a mask. This is useful for adjusting or excluding these areas, or even deliberately selecting light or dark areas in the image. Note that the mask is put at the bottom of the Layers stack as it just looks confusing at the top. Alt-click it to see what it really looks like.
