Outdoor Shoot

The photo was shot with the following settings
62 mm ISO 400 1/125 sec f / 4.8
At ISO 400, the ambient light reading was 1/125 sec f / 5.6
The speedlight was set to 1/8 power and gave a reading of f / 8
1- The available light was used as the main light. A speedlight mounted on a light stand was used as a kicker. The light achieved was good. But I would like to see more in the face. For the final shoot, I will have a reflector on hand to punch more light into the subject's face.
2 - a focal length of 62 mm was used. I wanted to use a "normal" lens. With the subject right against the wall, there's no need to achieve compression.
3 - Shot at f / 4.8. I wanted to throw the background out of focus while keeping the subject in focus. Looking at my source image now, I wonder if the blurring of the background was done in post. The subject could be sharper. But the fall off of focus works. For the actual shoot, I will shoot at a higher f-stop and do some blurring in photoshop.
4 - The choice of shutter speed was a combination of the available light and shooting a person. Kept it high enough to avoid blurring. I would have gone a bit faster if the available light permitted. But I didn't want to boost the ISO any higher.
5 - The camera settings were a response to the available light. I would have preferred shooting at ISO 100. But you can't always get what you want.
6 - The strobe lighting was fine. A speedlight was used dialled down to 1/8 power.
7 - There could have been more light and the shot would have been fine. Maybe even better since I could have shot at a lower ISO.
8 - I think I may have to blur the background some more in photoshop.
9 - Shoot with a gray card to have a reference point. The light from the strobe is minimal, contrasty and concentrated. It's balanced for daylight. Should it show in a overcast day, it won't be hard to correct in Photoshop.
