Crop Factor

The crop factor [1] comes from the fact that the Sensor in a digital camera is smaller than a frame of 35mm film. This means the digital slr crops out the center portion of a given lenses field of view, but the image is still at the full resolution of the digital sensor. This crop factor gives a lens on a digital SLR a smaller field of view than it would have on a film SLR, giving it the same field of view of a longer lens when compared to a film SLR.

Fireworks @ Pittsburgh, Independence Day 05'

美国国庆日焰火
Fireworks in America's Independence Day.

我们提前了几分钟吧,赶到钟华推荐的North Shore, 这地确实不错. 左边是downtown高楼林立,右边就是一会的焰火燃放点.
We were just a few minutes earlier. The vantage location was chosen by Roi. And it is really a nice place. We were very close to the fireworks.

今天全用的18-70mm套头,总共就放半小时焰火,没功夫换头了。全用的这个头，手动对焦放在无穷远，ISO 200，手动曝光，曝光时间从2秒到8秒不等，光圈f/12-f/22。
All pictures were taken by Nikon D70, 18-70mm kit lens. Manual focus at infinity, ISO 200, manual exposure, shutter speed 2'-8', aperture f/12-f/22.



不多说了,各色焰火争奇斗艳
