Show Suggested Answer Hide Answer
Suggested Answer: B

In good conditions, a pixel density of 250 px/m (80 px/ft) is required for identification purposes. This means that at this resolution, the image quality is sufficient to identify individuals, objects, or other details accurately. Identification requires the highest level of detail among the common surveillance objectives (detection, observation, recognition, identification). This pixel density allows for clear and precise visual information necessary for identifying specific features such as facial characteristics or license plates.

Increasing the shutter speed to 1/100th of a second? I'll just ask the sun to slow down a bit, that should do the trick.

Backlighting? Sounds like my camera needs a personal sun visor. Where can I get one of those P-iris hats?

Ah, the age-old dilemma of backlighting. Do I hear a drum roll for the correct answer? *drumroll* Polarized filter, of course! It's like a force field for your camera.

Increased shutter speed? That's like trying to outrun the sun. You gotta fight fire with fire, or in this case, light with light. Add some extra illumination, my friend.

P-iris technology? Sounds like something straight out of a sci-fi movie. I'll stick with the classic polarized filter approach.

Polarized filters are definitely the way to go for backlighting issues. Blocking out the excessive light from behind will really make the subject pop.

I think increasing the shutter speed to more than 1/100 s could also help in this situation.

I disagree, I believe adding additional light sources to counter backlighting would be more effective.
