The difference between souvenirs and taking pictures.

The difference between them lies in their different definitions and uses, and their different meanings.

1. Different definitions and uses: Memory usually refers to the memory reserved to commemorate a special moment or occasion, which can include words, photos, audio or video. Photographing only refers to images recorded by photography or camera.

2. The meaning of expression is different: as a souvenir, it emphasizes the memory and commemoration of the past and expresses the treasure and gratitude for the good times. Photographing emphasizes the expression and appreciation of the image itself, focusing on capturing the beauty of the moment and creating artistry.
