MANY people love to look at "Food Porn".
Food is one of the biggest reasons that people love to cruise and love to see what they will be eating.
I will take a picture of a dish but far less than I once did. I want to enjoy the presentation and the taste and taking pictures is somewhat of a distraction to my enjoyment and may also be distracting to others.
On a cruise a few years ago we had a tablemate who wanted to take pictures of everyone's appetizers, entrees and desserts. We indulged her on the first night but kindly asked her to just take pictures of her husband's and her own food after the first course of the second night.
It's nice to get pictures of the different dishes but it can go overboard.
