The exposure triangle
3 part series. Part 1
There are so many variables in taking a good image, but you have to know where to start before anything else. A correct exposure of an image is the best starting point. If you can gain the knowledge of that, you can break the rules later on and make it art.
The exposure triangle is defined by “The three facets of exposure for both digital and film cameras are ISO (which correlates to film speed), shutter speed, and aperture. In selecting the exposure for any given shooting situation, you need to choose some combination of the three that will yield what you consider the best exposure for your vision.” ~ ClickinMoms
