Thanks for your support & critique!
I use Adobe Photoshop CS2 as my main editing software. In adjusting the White Balance (the black & white points) in a photo, I use the Threshold function. In shifting the bar from left to right etc. I can see where the black point begins and from left to right where the white point begins.
Hope this helps. If not let me know :)
