You know that clicking noise you hear when pressing the shutter button to take your picture? It is the camera shutter opening and closing. Each click you make opens and closes for a set amount of time, usually a fraction of a second. Understanding how it works is one of the main pillars of photography, so it is listed as the first item on the list of photography for beginners. We recommend starting your reading on this subject.
It is essential to understand that the exposure triangle is made up of the ISO, the diaphragm, and the camera shutter. The three elements together are responsible for photometry.
The shutter influences the following two aspects:
- The amount of light reaching the camera’s sensor;
- By freezing the image according to the object’s movement;
- Remember that we are talking about concepts and that the camera’s shutter setting must go hand in hand with the other two elements, the ISO and the diaphragm.
Slow Shutter Speed For Visual Effects
One of the applications from https://skylum.com/blog/photoshop-alternative-for-mac in using shutters with slower speeds is related to prolonged exposure effects or light paint;
Leaving the shutter below 1 second (1″) makes it possible to create pictures with exciting results, especially in low-light environments.

Set The Safe Shutter Speed
If, on the one hand, we can use the camera shutter for visual effects, on the other hand, care is needed so that the photograph remains with frozen objects, especially fast-moving objects.
In this case, it is necessary to work with higher speeds, above 1/250.

Rapid Speed Shutter
Below, you will find a very calm and practical infographic with some possibilities within the photograph.
The goal is to exemplify the speeds needed for shooting with a 50mm lens and ISO 100.
At other lens and ISO settings, shutter speed also varies. Remember that the three elements always go together, ISO, diaphragm, and shutter.
