The word is made up of 'der Moment' (the moment) and 'die Aufnahme' (the shot/recording). So it literally describes a recording or shot (an image or a measurement) that captures a single, brief moment.
Dieses Foto ist eine perfekte Momentaufnahme des Sonnenuntergangs.
This photo is a perfect snapshot of the sunset.
The word has a literal meaning (a photo) and a figurative meaning (an analysis). The figurative meaning is often emphasized with the addition of 'nur' (only) or 'bloß' (merely), to show that the situation can change quickly.
Die hohe Platzierung in der Tabelle ist schön, aber es ist nur eine Momentaufnahme.
The high position in the standings is nice, but it is only a snapshot.
In the figurative meaning, 'Momentaufnahme' (snapshot) is often combined with abstract nouns. Typical phrases are 'eine Momentaufnahme der Stimmung' (a snapshot of the mood), 'der öffentlichen Meinung' (of public opinion), or 'der wirtschaftlichen Lage' (of the economic situation).
Die Umfrage liefert eine interessante Momentaufnahme der politischen Stimmung im Land.

'Foto' and 'Momentaufnahme' can both mean an image taken with a camera. 'Foto' is the general term for any such image. 'Momentaufnahme' is more specific: it captures a particular moment, often quickly, spontaneously, and without much preparation. The word can also be used figuratively when describing a situation only at a specific point in time. The words can be confused because a 'Momentaufnahme' can always also be a 'Foto'. If only the image matters, you say 'Foto'; if the brief, special moment matters, 'Momentaufnahme' fits better.
