>>3762386>You need to know the latter in order to calculate the former. You don't, because there's only one correct answer in regards to positioning.
Positioning wise, you'll want the sun at a slight angle coming towards you, the subject's face in shade, the late sun creating somewhat of a hair light effect. You can do either back right or left, I prefer the right because a speedlight will be on your left, but you could mix that up if you had OCF (for fill flash it's not required, though.)
Before you argue with me, your other options are sun coming in from the side (no) and straight on hitting the subject in the face (hell no). So like I said - there was one correct, obvious answer.
Bright clear day, that works out to be something like f9 1/160 100. Don't believe me, go out and try those exact settings tomorrow afternoon and get back to me. Might be off a third or so depending on time and clouds but not by much. Those are generally locked in stone. Most speedlights are roughly 75ws and those settings will change based on distance, but you'd usually be somewhere around 1/8-1/2 at common working distances.
And yeah, it's a stupid example. A good portfolio makes a good photographer. Well, that's subjective. But this - an actual test you can ask someone - it's something I'd expect a good photographer to know. Nearly every single one.
