When you use a simple bounced flash, always ask this:
“Where should the light be coming from?”.
And then that is where you point your flash.
So if during a custom workshop at Seneca College I want to light up Seneca student and reader Danny Lee with lighting that compliments a man and provides some modeling, I want light from the side – so I aim my flash behind me to the right:
If, on the other hand, I wanted to light him evenly, which makes the face look flat and featureless (and women like featureless because “featureless” also means “wrinkle-less), I would aim the flash straight behind me:
So today’s lesson: always watch where your flash is aimed, and enusre that that is where you would like the light to be coming from.
Here’s student Brittney, in a Seneca College workshop I did the other night:
Again: simple light: one off camera flash.
- From yesterday’s post you will remember that I first thought about the background, then about the flash. In this case I set my camera (in manual exposure mode of course) to give me a very dark background. I wanted no ambient light.
- And yes, you can use direct flash. I had a honl photo grid on a 430EX flash, driven by the camera’s 580EX.
- The 580EX was disabled from contributing to the actual shot: all it did was fire commands.
Another student – and here I added a background light too:
How did I do that?
TIP: always do a “pull-back shot”, where you see your setup.
As you see, here I asked a student to hold the gridded main flash; then I used a second flash with a gel and, to prevent the color from hitting the subject or shining into my camera, a flag (a gobo – “go between objects” – the Honl bounce cards are also gobos/flags.
First question I always ask myself when taking a flash picture is: “who does the work?”.
What I mean is: is the light in the image just from the flash? Or just from ambient? Or from both?
- When it is just from flash, the ambient needs to be dark (so I set my exposure for that).
- When it is mixed, I set the ambient so that is is the right level compared to the flash.
- In a mixed environment, sometimes I want to turn ambient UP (as in a party indoors), and sometimes DOWN (as in a dramatic portrait). The principle, however, is always the same: worry about what you need from ambient (from all-dark to bright), then worry about the flash.
And mixing is essential. This is how I look at most of my images:
WHICH LIGHT DOES THE WORK:
As you see, in most creative work, I like to mix the two light sources.
If you do not think of this, you will get unpredictable results.
So before hitting that flash, always ask first:
In this picture, do I want to mix light, and if so, what should the ambient light look like?
In the last few days I took two people’s portraits using just one off camera flash. Here’s Michelle and Adnan, respectively:
How did I take those?
First, I set the camera so that the ambient light looks dark. The room was not dark – it just looked dark to the camera, because I had set the camera up specifically to achieve that. 100 ISO, f/5.6, 1/200th second. You could use any combination of ISO-Apertyure-Shutter that gives the same brightness, but keep in mind:
- High aperture or low ISOs mean the flash has to work harder, and it may not have enough light
- The shutter speed cannot achieve 1/200th second; your camera’s fl;ash sync speed.
Then I added the flash. I used an off-camera speedlight on our right. I could have used TTL remote control or pocketwizards: I used TTL in Michelle’s portrait and Pocketwizards in Adnan’s. Light is light! Note that I put a Honlphoto Grid on the fl;ash, else the light would have lit up the background too. The flash (fitted with the grid) was aimed directly at the subject. To get the right exposure, I metered the Pocketwizard-driven flash, and I “flash exposure compensated” the TTL-driven flash.
Then I positioned the subject properly. I wanted the light to hit them just about from their front, with their face turned to get short lighting. I also wanted to see both eyes, even if one is only just visible.
And that was all. A one minute portrait, and a pretty cool one, no?
