I love catchlight in the eyes for portraits. I think it brings out the life and vibrance in a person.
To accomplish this I used a flash. Now the other thing that I had to do is figure out how to shoot with a flash at ƒ/1.8 outside in the sunlight. This is where High Speed Shutter Sync does the trick. This is when you can take a photo using a flash at any shutter speed and are not locked into the sync speed of 1/250.
I always start with the off camera flash 45º to the left or right of the subject. If their body is facing left then that is the side the light will be placed.
The light is generally 45º above their head. I look to see if the flash causes a shadow that hits their lips. If it does I then lower the light till the shadow is just off the lips of the person. This can also be controlled by lowering of raising the subject’s chin. So you have to be aware of light placement throughout the photo shoot as you most likely will have them move their head around.
This is my setup. I have an Alienbees B1600 with a white umbrella that I am shooting through. To sync at the High Shutter Speeds I am using the Pocketwizard TT5 with the AC9 that plugs into the back of the Alienbees using a phone cord connection.
Now with the AC3 on top of the Pocketwizard Mini TT1 you can control the power of the Alienbees from your camera wirelessly. I use the M setting on the AC3
Here is the chart of how that would work:

Now the cool thing is I can choose to change my settings on the fly. Here I was shooting at ƒ/1.8 of the senior in front of her high school. I thought they may want to see the high school a little more. To do that I needed to stop down to different ƒ-stop.
|Nikon D5, Nikon 85mm ƒ/1.8G, ISO 100, ƒ/7.1, 1/320|
I just powered up the flash from the camera and dragged the shutter from the 1/4000 speed to 1/320.
Here is another example where I needed to change the ƒ-stop.

Again I realized the client may want to know what was on the banner in the background. Quick change without moving my feet.

Why use such a powerful flash and not just a speedlight. Well the recycling time on a speedlight can be pretty slow.

Profoto B1 500 AirTTL Battery-Powered Flash
When you put together a kit of 3 or 4 lights you can see your money costs really go up with the Profoto system.
The Profoto gives you one thing that the system I designed doesn’t give to you and that is TTL. As a general rule when working with studio strobes once you put them in place and take your first photo to check for exposure your lights generally don’t move.
Here is the main reason I hate TTL–it is unpredictable. Sure I must take a reading then set my lights without TTL, but every time I take a shot the exposure is not consistent. With TTL just a slight movement with your camera, the model or something in the background will impact your meter and tell the camera and flashes to make an adjustment.
