【明報專訊】I began to talk about "foodporning" in my last column. The term refers to the highly popular practice of taking food photographs right at a meal and then immediately posting them onto social media sites. It may be transforming social relations between friends. I am not sure where the saying "let the camera eat first!" has originated. It is very likely Hong Kong phraseology. But a funny line like this seems to be embedding a great deal about friendship, aesthetic preferences and even competitiveness in our social life.
