Event Photography Expense

Dear Experts

We are a Pvt ltd compnay acting as channal partners & distributors fo Mining Equipments & services. We have recently vetured into Mining equipment assembly at our warehouse. For this purpose we carried out photography of the entire assembly process. My question is under which nomenclature these event photography expenses be booked ? These Expenses are meant for our internal training purposes and records
