So if I put the SB600 at full power TTL and 1/200 shutter speed and let's say f/11, would that achieve similiar effect to that picture in the first post?
Your best bet is to setup andd try some shots, but you're looking at an image that was made with
at least 4 lights
Look at the shadows, and the highlights.............There is a light above and behind them (probably mounted to the top of the orange playground equipment behind them as a hair and rim light). It's casting a shadow
in front of them.
There are 2 side lights, both hard light (a strobe with no modifier), camera right and camera left and somewhat behind them.
Look at the guy on the right. See how bright his cheek is, and the glare on the blue PG equipment to the right of him? That gives you an idea of how high the light was.
The light camera left was further back. See the bright spot under the right ear of both guys on the left? See the bright spot on the black playground equipment in the upper left corner?
Plus they were also lit with low power fill on the same axis as the camera lens, either a pop up, a shoe mounted speedlight or possibly an umbrella or softbox because the light looks somewhat modified.
Take a look at the evergreen tree and it's shadow just to the right of the group in the background. That will give you an idea of where the Sun was when the image was made.
1/200 at f/11 will be plenty, if you nuke 'em with 4 lights too. One SB-600 won't cut it.
