Overview:
Old school!
We like your overall strength at the traditionally less important positions,
but make no mistake about it: this team is about strength at the running
back position. And we think it will be a legitimate contender. Somewhere
Terrell Davis is smiling.
Nonetheless, we'd be remiss if we didn't at least mention the relative lack
of strength at quarterback and receiver. These are usually survivable
weaknesses, but we'd feel better if we knew you were committed to zealously

I think the more interesting questions are these:
• Why did some states, e.g., Michigan and Wisconsin, develop public
universities of high quality, breadth, and depth when certain other
states with arguably equal or greater resources, e.g., NY, NJ,
Pennsylvania, did not develop comparable public universities?
• Why did some southern states, e.g., Virgina and North Carolina,

通常一个fin的会比较大，长。三个的会相对短一点
The hold of the surfboard increases with more depth but generally makes it
harder to turn as well. 3-4 inch depth is standard on tri-fins and longboard
single fins typically have a depth of nine inches.
默认前提当然是放大率相同的情况了。刚才打错了，应该是f^2/光圈/crop系数，所以你的20饼干弥散圆直径会更小。 http://photo.net/learn/optics/lensTutorial
If we frame an object the same way with two different lenses, i.e. M is the same both situations, the shorter focal length lens will have less front depth of field and more rear depth of field at the same effective f-stop. (To a first approximation, the depth of field is the same in both cases.)
Another important consideration when choosing a lens focal length is how a distant background point wi... 阅读全帖

刚才那DOF Master算了一下。因为43的circle of confusion略小。
注意是同样焦距，不是同样等效焦距。
比如同一个200mm毫米的镜头，射到F/8，目标距离20 ft，
在43上，
Subject distance 20 ft
Depth of field
Near limit 19.7 ft
Far limit 20.4 ft
Total 0.71 ft
In front of subject 0.35 ft (49%)
Behind subject 0.36 ft (51%)
Hyperfocal distance 1094.3 ft
Circle of confusion 0.015 mm
在D700上，
Subject distance 20 ft
Depth of field
Near limit 19.3 ft
Far limit 20.7 ft
Total 1.42 ft
In front of subject 0.68 ft (48%)
Behind subject 0.73 ft (52%)
Image posterization is caused by low color depth in the presentation media.
Color depth and Dynamic Range are two different things.
You can have a low color depth monitor displaying high dynamic range image
but still showing undesirable color posterization.

Stopping aperture down increases depth of fi eld, making the
foreground and background sharper. Stop aperture down
too far, however, and diff raction will actually cause the image
to lose defi nition. The eff ects of diff raction are partly infl uenced
by the size of the pixels in the camera image sensor,
but with the D800/D800E’s high resolution the eff ects generally
become noticeable around f/11. When you need more

Resolution of camera lenses where are the limits – and why?
Some users of Zeiss lenses are so enthusiastic about these optics that they
believe Carl Zeiss can do won-ders. Well, this is not exactly true. The fact
is: Carl Zeiss has to adhere to nature's laws just as anybody else. So far,
Carl Zeiss's physicists have found no way around it.
