(The following passage on food photo sharing contains 38 GRE words. If you find it difficult to understand, read through the explanation of the meanings of the words (given with illustrative sentences) and then reread the passage.)

The food photo sharing phenomenon (or what you might call the visual department of gastronomy) is in full swing. New tools such as Foodspotting and Eat.ly are constantly proliferating. Add in the photo-handling capabilities of sites like Foursquare and it’s no surprise that the “eat and tweet” trend has inundated social media feeds. Interestingly enough, this flood of food images is being engendered not just by gourmands or even specialist food sites, but ordinary philistines like you and me who have no expertise in food beyond our own pedestrian predilections. Showing – not just telling – others what you’re eating is becoming mainstream. So is vicariously enjoying others’ food. Why is everyone suddenly so keen to snap their snacks (and gorge on images of the food that others eat)? Does this simply reflect a universal human desire to share things that gives us pleasure? Is it showing off or, is it a drive to gain status? What is the genesis of this new drive? And how is it changing our approach to food and eating?

There are lots of theories about why people like to share pictures of food. Some experts suggest it’s because eating is one of society’s most essential communal activities, and sharing food photos is the next best thing to convivial experience of eating together. Others speculate that food photos allure us because we have always started a meal by ‘eating with our eyes’, preparing ourselves for the actual culinary experience by savoring its visual aspects first. Others still, conjecture that food has become something of a status symbol, and sharing a photo of a meal, particularly from a buzz-worthy restaurant, is as much about establishing one’s place in the social media hierarchy as it is about documenting what we ate today.

The interesting thing about food photography is that it combines two subjects that really resonate with society as a whole: food and culture. Meals, for example, are often a time when people come together to celebrate life and human relationships. So, a food photographer is a visual food anthropologist. It’s not just about the food on the plate; it’s also about the context: the moments, the connections, the scenes, the places, the stories. Think about how people relate to food and what connects them to it. Some of the most interesting photographs come out of this relationship. Mobile phones and social media are at the heart of the food image vogue because social media provide the space where a lot of us document and curate our lives and, mobile phones allow people to capture and share their experiences wherever they are. A new element has enlivened the routine of dining: snapping photos of your meal before you eat is now becoming commonplace in places ranging from the fanciest restaurants to your local café and even in less reputable dives.

Of course, filtered photos of food are no surrogate for the experience of the meal itself: they cannot replace the aromas and sensations of preparation and consumption or, the conversations that take place at the table. As for the snaps themselves – these are merely the yeast with which we leaven the pleasures of the Net. Now that’s food for thought!
