Taking photographs of fireworks is great fun -- and very challenging.
Veteran photographers know these tricks, and I wanted to share some with you.
Now, you can take photos as well as the stereotypical creepy-uncle-
photographer.
1) Get your camera on a stable surface.
2) Turn off your flash.
3) Get something else in the photo besides the exploding firework to give
perspective and set the scene.
4) Set your focus once on a distant light, then swit... 阅读全帖 |

There are two flash metering mode, Evaluative vs Average. you can google
what it really means, but it seems
1. when use flash as main light, use evaluative metering
2. when use flash as fill light, use average metering
If you are controlling multiple flash on a trigger and cannot set metering

不知道各位是否知道一张照片是怎么形成的呢? 其实照片就是「让底片嚗光，纪录那一
刻的光线」，所以有人说摄影就是「捕捉光和影」。那么对于一个初学摄影的人，甚么
东西是必须要认识的呢? 答案便是嚗光铁三角：底片感光度(ISO)、光圈(Aperture)和
快门速度(Shutter speed)。
底片感光度(ISO)
在数码相机还未流行前，摄影师用的是菲林(Flim)，而菲林上通常也会有一个数值如
ISO50/ISO200/ISO1600等，其实这个数字便代表了底片的感光能力，数值越高，吸收光
的能力越强，越适合在黑暗的环境下进行拍摄(但无论感光能力多强也不能在"完全没有
光"下的环境拍摄！)。那么甚么时候应该用甚么数值的感光底片(在数码相机便是设定
ISO为甚么数值)呢? 其实在正常情况，ISO越高(感光能力越强)，讯噪便越强，在相片
比较暗的区域越是明显，大家可以看看以下的例字 (Photos from dpreview.com)：

Does the camera feature image stabilisation?
Image stabilisation is required when using fixed or zoom lenses with
telephoto focal lengths and variable maximum apertures. As the X100 features
a fixed lens with a maximum fast aperture of F2, image stabilisation is not
required as this combination will still allow photographers to successfully
hand-hold the camera in low light conditions.

光圈(aperture):an aperture is a hole or an opening through which light
travels. More specifically, the aperture of an optical system is the opening
that determines the cone angle of a bundle of rays that come to a focus in
the image plane.
光圈直径就是上面解释的那个hole的直径 |

2 X 0.5 ~= 3. 佳能的百微，全开f/2.8, 放大率1， 有效光圈会降低到2.8 + 2.8 X

缩光圈的情况下，影响会更为显著。用Excel作了个简单的图，大家对比着看看吧。

苹果于周三发布了数码相机Raw兼容更新2.7版本。此次更新的目的是扩展Aperture
2、iPhoto'08和iPhoto'09的RAW图像兼容性。
虽然只是小幅更新，但是此次更新将六款数码相机添加到兼容列表，分别是：
Canon EOS-1D Mark IV、 Canon EOS 7D、Canon PowerShot G11、 Nikon D3S、 Nikon
D300S 和 Nikon D3000。有需要的用户可以通过Mac的Software Update软件更新获得
新版本，苹果官网的Support技术支持页面尚未提供下载链接。
在相机兼容性方面，苹果的支持脚步要比Adobe缓慢许多，使得一些用户不得不割
舍Aperture和iPhoto，用Adobe的产品。Aperture是Mac电脑优化照片的软件，提供多种
工具可用于润饰照片、管理图库、在线共享作品，以及印制专家级设计的图片册。

显。但是过低的时候又容易问题曝光不够，shutter speed和aperture之间难以协
调。
好的机器可以在ISO, aperture和shutter speed之间做出优化。出现最好的效果。
楼主的摄影水平比起我来说已经算大师了！ |

第一张要用手动。Aperture Priorioty.
due to the longer distance, automatic mode will certainly give you a small
Aperture, which brought out the result you don't like. |

aperture的优势了， 跟open sight有啥区别了。 |
