Watt-seconds is the usual measurement for the power output of professional flash systems. 1 watt-second is equivalent to the power of 1 watt for a period of 1 second. It’s used because it’s a measure of raw power output independent of any lighting modifiers, angle of coverage or reflective surfaces
Highly complex photo-editors offer so many tools that the interface can quickly become cluttered and confusing. To get round this, most offer the ability to produce a custom workspace containing only the tools you use most often.
The steps taken by photographers at various stages of the image capture, editing and sharing process.
