Starting with an maximum aperture of F8, stopping down say 2 stops would give you F16.
Background is either dark or you want to make it dark so you underexpose by say 1-2 stops. This will produce a lot of noise so you use a lower ISO (200).
Sunny 16 rule (it’s not sunny but you have a lot of sun in the frame) suggests a shutter speed of around 1/200sec.
With -1EV that gives you a shutter speed of around 1/500sec?
