Canon Speedlites and Nikon Speedlights are small, off-camera flashguns that can provide big results - if you know how to use them properly. Acclaimed Boston photographers Lou Jones, Bob Keenan and Steve Ostrowski guide you through the technical and creative aspects of how to get the most out of these powerful tools in this indispensable guide, packed full of inspirational images and comprehensive diagrams of the lighting set ups used to capture them.

They are significantly more advanced, lighter and considerably cheaper than a standard flashgun, and have many advantages. They are small (and cheap) enough that a number can be carried in your kit, and they can be used in combination, triggered wirelessly. They use through-the-lens (TTL) metering, which allows you to use the in-camera LCD and histograms to calculate the required power/direction, rather than havng to use a light meter or trial and error. They use proprietary, dedicated technology (from Canon and Nikon) that means there are no compatability issues.

Getting the most out of them, however, remains a mystery - most photographers still just use their speedlights in the same way as a standard flash gun. This is where this book comes in.

佳能闪光灯和尼康闪光灯是小型的离机闪光灯，可以提供很大的效果--如果你知道如何正确使用它们。著名的波士顿摄影师Lou Jones、Bob Keenan和Steve Ostrowski在这本不可缺少的指南中，从技术和创意方面指导你如何充分利用这些强大的工具，其中充满了鼓舞人心的图片和用于拍摄这些图片的全面灯光设置图。

与标准闪光灯相比，它们明显更先进、更轻、更便宜，而且有许多优点。它们足够小（而且便宜），可以在你的工具包中携带一些，而且它们可以结合使用，以无线方式触发。它们使用通过镜头（TTL）测光，允许你使用相机内的LCD和直方图来计算所需的功率/方向，而不必使用测光表或试验和错误。它们使用专有的专用技术（来自佳能和尼康），这意味着不存在兼容性问题。

然而，如何最大限度地利用它们仍然是一个谜--大多数摄影师仍然只是以与标准闪光灯相同的方式使用他们的速射灯。这就是本书的意义所在。
