For the on location shoots I will use the natural light there or the standard overhead lighting because There will not be room to set up the lighting or the type of plug socket needed for the small ring light I have at home.
For the interview I will use overhead lighting and front facing lighting because I only have two lights maximum (one if I decide to use white light instead of warm light).

Update
I was not able to use natural light in my second + usable shoots due to weather and so I just used the overhead fluorescent lights in the workshop. I didn’t use my ring light because the overhead lights were strong on their own and didn’t cast dramatic shadows on the interviewee.
