I would suggest that in both cases you are well within the aerial work category, with the ATPL/CPL being an employee of your company and you being the photographer of the company. The same as you being the CPL and hiring a photographer. Only if the ATPL/CPL carries fare paying passengers either A to A or A to B for the purpose of public transport would you need an AOC.
Hope this explanation helps
If nothing else it's 'As I See It'
