Abstract

fetched live from OpenAlex

Food photography is an increasingly popular phenomenon, especially on social media. There are over 215 million photos on Instagram with the hashtag “food.” There is a growing trend to showcase the food on social media, as both health and “food art” has become part of popular culture. The purpose of this project is to explore how the photo angle utilized in the image influences a number of consumer outcomes, including evaluations of the food itself, the company, and desire to interact with the image. Specifically, pictures of food commonly employ either a three-quarter downward looking angle (as if you were sitting at the table ready to take a bite of the food) or an overhead “bird’s eye view” angle (as if you were standing over and looking down at the food). Through a series of four experiments we show that photos of food taken from a three-quarter downward looking angle are evaluated more favorably in terms of perceived taste, attractiveness, and desire to eat the food, while photos of food taken from an overhead angle create brand perceptions associated with progressiveness and trendiness.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
