By BRENT KENDALL And JESS BRAVIN
WASHINGTON—The U.S. Supreme Court ruled Monday that Monsanto Co. MON -1.19%
can use its patents to prevent farmers from planting later generations of
genetically engineered seeds without paying for them.
Monsanto's Roundup Ready seeds render crops resistant to weed killer and are
planted on much of the nation's farm acreage. But unlike many inventions,
Monsanto's patented biotechnology is self-replicating, prompti... 阅读全帖 |

At strawberry farms across southwest Florida, there's an unusual sight.
Workers aren't picking strawberries, they're destroying them.
Why Florida farmers are destroying, rather than picking, their strawberry
crop.
"We've got more berries than we know what to do with," said Matt Parke, a
strawberry farmer.
Parke said that he was forced to tear through 60 acres, nearly half of his
crop, to save his farm. He |

- the picture is opened with Window Photo Gallery
- click "fix" to top menu
- choose "crop picture" on the right menu
- select "proportion" as 16:9
- then you can scale the cropping size, in the 16:9 ratio

光:
每个人的喜好都不尽相同,个人比较喜欢可爱系列的娃。 光线对我而言尤为重要,我
喜欢看起来“亮亮”的感觉。娃还很小,不敢用灯。所幸我的房间的窗户可以提供足够
的光线,特别是每天早上的时候由窗户透进的自然光很是迷人。我经常还会把曝光加一

娃的表情:
娃的表情对我来说是最最重要的了。所以每次都要花很长时间和宝宝玩,逗他开心,自
后才开始拍。刚开始的时候娃很怕镜头,经常一看见相机就没表情了。花了很长时间才
让她适应。我比较喜欢娃笑或搞怪的神情,个人的偏好比较不文艺,记录的影像中都没
有她哭得表情。(她哭得时候我哄都来不及,别提照相了)。

我并不是想吹嘘D700,只是认为D700/D3更适于婚纱摄影,而1Ds3和D3x更适于摄影室和
fashion photography。其中一个原因是当你在实地拍摄的时候,连拍很重要,如果加
了手柄后,能达到10fps的话,肯定比5fps强很多。21mp当然比12mp在后期制作特别是
crop中很有用,但是如果你作为婚纱摄影师,需要提高自己的产出效率,就必须想办法
降低自己后期制作的时间。换句话说,争取一步到位,直出做一点点调整就印了,否则
每个都要crop你的成本就会大大提高。这也就是为什么很多婚纱摄影师只拍jpeg不用
raw的原因。再加上高iso对婚纱摄影师非常重要,有的时候在一个黑暗的教堂或者室内
,你控制不了光源,而那个瞬间就那么宝贵。所以在这些点上D700的优势比1Ds大一些
。并不是说从参数上D700超越1Ds3。很多人还认为5D2在D700面前时完胜,那些对焦点
根本没用呢。

你见了人说"you would have to move closer to the subject"? 因为人是用同一幅面
,换了光角为了KEEP SAME FRAMING 只能走近. LZ 换了更光的15MM 但用了16X CROP 幅
面, KEEP SAME FRAMING 的话正好要站在原地不动.
所以, LZ 的两张图1.6X CROP 用的是15MM, FF用的是24MM, 15X1.6=24, 这两图是站在
同一地方拍的, 透视是一样的.
15MM 在1.6X CROP 拍的就是等同于15MM 在FF 上拍了从中间挖一块出来, 挖出来的一
块恰好等于24MM 在FF上因为15X1.6=24.

在文章之前引出这个问题并不是笔者要故弄玄虚,X100对于用户到底是美酒还是
毒药,实际上很大程度上将取决于你的拍摄习惯和拍摄内容。如果你对旁轴胶片
还相当陌生,鲜有接触,不习惯传统旁轴胶片的拍摄方式。那么毫无疑问X100

如果能在保持D700 ISO表现的同时,提高像素到20-30MP(提到高40MP还不伤ISO估计
没戏),那还是很美好的一件事。
像素高点总不是坏处。给了很大的crop的空间。比如到时候28-300,切一下就差不多
600mm的感觉了。当然这个头有没有那么牛,就是另一回事了。
最好D800提供几个crop的选项。省着后期自己切了。这个对大鸟应该有好处。
但是希望能支持自选size的RAW。比如如果搞出一个40MP的芯片。但是支持10MP的RAW,
并且对噪音和DR优化。RAW的loseless压缩也很重要。说是硬盘越来越大,raw的size还
是越小越好呀。要么一张照片50MB, 20 1个G还是很吓人的。
视频主要是支持的video size稍微多一点就好。动不动就720p太浪费。搞个640x480就
好了。加上上面说的crop。对焦过得去就行了。关键是拍摄过程中的控制要灵活一些。 |
