Sweet piece from Lighting Essentials . Teaser paragraph ---->
I placed the strobe at a height that was slightly over the top of her head. This allowed a natural look to the resulting shadow, letting it fall slightly down. If I had placed the light too low, and it had lit her under the chin, the result would be comical... too high and it has an un-natural feel to it as well. I placed a small bit of diffusion over the front of the flash to give it a little more diffusion.
I knew that the exposure on her back was probably in the neighborhood of f-16 at 1/125 due to the F16 Rule: F-16 at the 1/ISO for exposure in bright daylight. ISO 100 made it f-16 at 1/100 or 1/125. So now I knew that in order to get my exposure to look normal, I would render the exposure at even... f-16 from the sun at 1/125 and the flash close enough to the subject to give me f-16. Just to make sure, I popped a shot without the flash going off and zoomed in a bit to see what effect the light without the flash had on Megan.
As you can see, the test shot actually showed me the sky as being natural, the highlight from the direct sun was manageable and the backlight on the weeds was sharp and clear as well. So all I had to do was add my light and shoot.
I knew that the light I was providing would light her up as well as the weeds so I placed the stand and the strobe where I knew f-16 would be at 1/4 power and did my test shots. I liked the shot, and with only a minor correction in the placement of the strobe (I moved it in about a foot), started shooting. I needed to bring it in a little due to the nature of her dark coat and wardrobe.
