Depth Perception- uses both eyes- how does a camera lense allow depth perception?

Watching a show about our eyes last night, I heard that with the slightly different images our eyes capture our brain puts them together and that is the basis of depth perception. How, then, with cameras, can we still gauge how far away things are in pictures and in movies, since cameras have only one image to capture? Is it mainly just using reference objects that we know the size of roughly, like humans or cars to guess how far something in a picture is? Did that make any sense?

Yup, you pretty much have the answer. Without stereoscopic (with two eyes) vision, the brain falls back to other cues like relative size (things farther away look smaller) and occlusion (things behind get partially hidden by things in front). Lighting also plays an important role, like the location of highlights and shadows. There are also a few more subtle cues, like objects appear hazier and slightly bluish when they are far away.

Accutire Tread Depth Dial Tire Gauge $12.99 Two essential functions to keep your tires rolling! The Accutire Tread Depth Dial Tire Gauge allows you keep an eye on tires' tread depth and on the tire pressure, with one smart gadget. By maintaining proper tire pressure and monitoring tread depth, you can increase fuel efficiency, reduce tire wear, and keep your vehicle balanced. Every driver should have a Accutire Tread Depth Dial Tire Gauge! Tire pressure has a huge influence on the performance and fuel economy of your vehicle! Proper tire pressure helps your vehicle's tires maintain traction with the road, which is essential for balance and proper handling. If the tires are performing as they should, you're using fuel more efficiently. Just a quick check of the tires with the Accutire Tread Depth Dial Tire Gauge once a month will let you know if your tires are properly inflated. The Accutire Tread Depth Dial Tire Gauge also measures tread depth - another indicator of the tires' performance. If the tread has worn down, the rubber is thinner and smoother, making a blowout more likely. Plus tire tread improves traction, which improves vehicle handling.

The Accutire Tread Depth Dial Tire Gauge measures 0-60 PSI in 2 lb units. The easy-to-read dial display is surrounded by rubber for impact resistance. The tire gauge fits comfortable in the palm of your hand. When not in use, store it in the included pouch in your glove compartment. At the same time you're checking tire pressure, you can check the tread depth and get the full picture of what's going on with your tires. The Accutire Tread Depth Dial Tire Gauge simplifies tire maintenance to keep you rolling! 0-60 PSI (in 2lb increments) Tread depth indicator Increase fuel efficiency Reduces tire wear Storage pouch included

Verban Depth Gauge -- How to use this Implant Surgical Instrument

Setting Iraq issue aside, what other foreign relations debates shall the voters like to see from candidates ?

to gauge more in to the depth and perceptions of the candidates? Even internal security also can be forgotten for a while.

As a matter of fact the whole world is keenly watching and shall be more interested what Obama and Mc Cain have to say on many of the outstanding issues, Clinton being a known entity for most.

The number one issue in my opinion is Sudan, and I would like to hear a candidate specify a Darfur policy, as well as give some knowledge about southern Sudan. I would also like to see some discussion on Venezuela/ Columbia, Cuba, Kenya, North Korea, Pakistan/Afghanistan, Taiwan/ China, Kosovo, and Canada/Mexico/ NAFTA. All of these areas are global hot spots, and I want to know what candidates know and think about each of these areas prior to receiving briefs.
