Edmund Goulding, director of Grand Hotel, The Dawn Patrol and Nightmare Alley, instructs students as to how to properly shoot a kiss for the camera at Columbia University during a special motion picture class in 1927. Not an actual academic major for decades the school offered up what I can only assume was a one time deal or an elective course on movies. I couldn't say for sure because there is no further info on the photo. I wondered if Goulding grabbed the heads of his stars when setting up a kiss. Probably not.
