The same reason color blind people lead folks through booby trap jungle.

I need more.....

You'd get more distortion with color.

Hmmm....I like pics that are detailed....can see more.

So, a grainy, B&W, poor quality video is better for tactical review?

Some of the videos released to the public are less quality than 1960s stuff.

Less distractions. I worked with a guy in construction and we had to clear some trees for a retention pond. He was pointing out all kinds of critters and trails on the way in but couldn’t see the orange ribbon on the trees we were supposed to clear. The orange ribbons were all I could see. lol

There are no color blind military pilots to the best of my knowledge. I'm red/green colorblind and there was a long list of MOS' that it kept me out of including EOD and military police. It supposedly kept my grandfather, where I got from, out of WWII.

Remember, Your trail cam is taking pics at a max of maybe 50 yards from a stationary position.

Those videos are being taken at heights of 10,00 feet or more from a aircraft that is moving at 500-700 mph.

They also use mostly night vision. Thus the B&W and graininess.

All valid camera points.

But, I still believe better images could be obtained....even from fast moving, high flying aircraft.

Satellites get great images from space. How fast and far away are those?

Another way is to use a recording device instead of the human eye. Recording devices can be photographic films or electronic detectors. Unlike the human eye, these methods have an advantage in that exposures of faint objects can made over a very long time. The exposures can be as long as 45 minutes per image. The images can then be added together to add up to exposure times of up to 38 hours for each filter. The longer an exposure is, the more light falls on the film. As long as the image is held very still, eventually an image of the faint target will appear. Another advantage of recording devices is that a permanent copy of the observation is obtained.

Hubble looks at objects which are so distant and faint, that even with highly sensitive CCD detectors (which are many times more sensitive than the human eye) it must expose for long periods of time. These exposures can be for 30 minutes or more. Sometimes hundreds of half-hour exposures are added together to produce one very long exposure. Observations using CCD detectors can also be added together, which is something that cannot be done with photographic film.
