The noun 'Auslösung' (triggering / release) is derived from the verb 'auslösen' (to trigger / release). The ending '-ung' turns a verb into a noun and is always feminine, hence 'die Auslösung' (the triggering / release).

The deployment of the airbag saved his life.
You can recognize the exact meaning of 'Auslösung' (triggering / release) from the context. In connection with cameras, it is about taking photos. With alarms or mechanisms, it is about starting a process. In the context of crime or kidnappings, it means the payment of ransom.
Stelle die Kamera auf Serienaufnahme für eine schnelle Auslösung.
Set the camera to burst mode for a fast shutter release.
In the meaning 'Start eines Prozesses' (start of a process), 'Auslösung' (triggering) is often used in a genitive construction to specify what is being triggered. Typical examples are 'die Auslösung eines Alarms' (the triggering of an alarm), 'einer Kettenreaktion' (of a chain reaction), or 'einer Krankheit' (of a disease).
Stress kann ein Faktor bei der Auslösung von Kopfschmerzen sein.
Stress can be a factor in triggering headaches.
In the context of photography, 'Auslösung' (shutter release) is a technical term. People often speak of a 'schnelle' (fast) or 'langsame Auslösung' (slow shutter release) to describe the camera's reaction time.
Für bewegte Objekte brauchst du eine Kamera mit kurzer Auslösung.
For moving objects, you need a camera with a short shutter release time.
recording / admission / uptake
'die Aufnahme' and 'die Auslösung' can both occur in connection with a camera. 'die Aufnahme' means the photo itself or the process in which an image, sound, or data is captured. 'die Auslösung' means the brief moment when you press the camera's shutter release so that a photo is taken. Confusion is possible because the shutter release leads to the shot. But they are not the same: the Auslösung is the start caused by the button; the Aufnahme is the resulting image or the whole recording process.
