The inverted LUT is of interest since I have a set of 1000 images from  
ten years ago that are only 320x240 pixels Jpeg and when I use the  
macro with the changes they are all process as if they are inverted  
and so I put back the run("Invert") statement for that batch and they  
come out OK.  Strange.  I'll give a try modifying the macro to if-test  
using is("Inverting LUT") to decide whether to run("Invert").
