Clearly shifting the lighting values is the only way to be able to see them. The Black Dog seems to have but purple highlights, not unlike Ravens.
I think it can be done digitally if the camera is initially setup to capture small variation in light levels in the dark region.
That's why I'm happy to have the Yellow Lab colored dog, 'cause I can actually see her on a dark night in the back yard. The Black Dog could easily work outside in the night for the CIA as a spook....
Exactly like ravens!
I have clip-on flashing LEDs for my dogs, if we’re outside for very long at night so I know where they are.
Since they guard silently at night, *not* seeing them is an advantage.
Imagine a burglar’s’ surprise.
:D
When I was young and lived at home, my dad was always yelling about my Dobes “suddenly appearing from nowhere” and goosing him when he came home from 2nd shift at midnight.
Freaked him out every time.
