Well said Peter. I'm trying to get my head out of family trees, old family pics etc, and so my brain is not completely in photography mode. Having to read my own threads as a refresher
Attached is a B&W conversion from a false colour IR shot. So custom WB as Peter said and camera D100 with Hoya R72 filter. Taken in RAW, converted to 16bit Tiff, then processed with Khromagery False Colour plug in, then converted to B&W then resized and saved as jpeg (8bit) to post here.
