How do you measure the return on a photo shoot?

You watch whether the photographed dish is ordered more on the menu, in the app or on WhatsApp in the following weeks. Likes do not measure it if the new photo is not where the order is placed. Note, the week before, how often that dish is ordered and how often people ask from the photo. The miss in Madrid is changing the photo and judging the month by reach, while the digital menu still shows the old image. You keep a plain note: dish, where it was published, and whether orders for that dish moved.
