Here's the situation.  I have a photoshoot, it's raining cats and dogs.  What does one do?

We were in upper Hilo and it started to rain.  This particular property had a huge shed used to store construction equipment and a really big door.  I used the light (overcast) coming in from the door as my main source of light.  It's nice and soft but as you can see, if the model wasn't blonde, the hair would have disappeared into the background.  What to do?

I set up a off camera flash (OCF) on a light stand triggered by a remote triggering device to add some depth into the photo.  As you can see, there's a forklift to camera left and a smashed ATV to camera right.  They added to the quirkiness of the photo.  There was some light coming in from the windows but not enough to do anything.  Flash unit was a Canon 550 EX set to manual and 1/128 power.  It added enough of a kick to add depth into the photo.  The image is framed to show the immenseness of the shed.

This is a closer shot of the same image.  Now with the hair light adding a kicker to the hair, the image has more depth.
