Btw- I really don't think the last picture can be detected by the visible eye. Due to the Dark color, resolution and lack of illumination. I was attempting to compensate for this by changing color curve's. For better luminosity.
Anyway, my experiment was a failure. And I might add, I posted the wrong pic anyway.
(i meant to post the illuminated pic only. Not the colorized one.) Alex, or whom ever could you please "delete" the last two pics.
btw- How did you "detect" the last pic, I really don't think it can be done. If you can tell me how you would do it. I would be appreciative.
