As it turns out, most mechanical shutters actually sweep down the sensor, as opposed to sweeping left or right. This is done partly to reduce the effect of rolling shutter (since the distance down the rectangular sensor is shorter than going side-to-side). The shutter is composed of a “first curtain” that drops down (exposing the…

Secondary effects: Shutter speed
The secondary effect with the easiest of the three to understand is probably the shutter speed. A fast shutter speed can freeze action. A slow shutter speed will blur motion. If you are shooting sports, chances are you are going to want to freeze their motion. To freeze motions that a person can do, your…
Putting it all together: Exposure
“Exposure” is the choices made in the Exposure Triangle and how it looks in the final picture. An image is properly exposed when it is not too bright and not too dark.[1] Here is an image I took on July 9, 2014. The exposure triangle settings for this image were: Aperture: f/6.3 Shutter Speed: 1/800…
Primary Effects: Shutter Speed
The shutter speed is the amount of time that the sensor is exposed to the incoming light from the scene you are photographing. The number we assign to this parameter is expressed as a fraction of a second, for example 1/30 1/2000 ½ 15 The last one, “15”, means that the sensor is exposed to…
