I was hired by a Udub (University of Washington) professor for an environmental portrait and head shot for her website and publications. This tutorial reviews my thought process and setup for the shoot. Step 1: Analyzing the location An environmental portrait shows a person in his or her surroundings. For example, showing a scientist in his laboratory. In this case, my client wanted a shot in front of her academic building. It was 1 pm on an extremely sunny day. So, how to set up the shot? I decided to set up the shot so both the building and subject were in shade. To do this, I used the shady side of the building as a backdrop and then placed my subject underneath the shade of a large tree. By doing this, I was in total control of the contrast. If either my background (the building) or the subject were in the sun and the other was in the shade, there would be too much contrast in the shot. If, for example, I used the sunny side of the building as a backdrop it would be very bright and distracting from the main point of interest, which is always your subject.
Step 2: set up your lighting If this portrait was taken at a wedding, I wouldn't have bothered lighting it. I would have taken a natural light shot either in full shade or directly in the sun with the sun to my subject's back. However, this shoot was not for a wedding. I needed a totally different look, a professional, commercial look, which in my book means the shot should be lit. For lighting I used my 580exII flash on a stand with a shoot through umbrella. This setup is not powerful enough to overpower bright 1pm sun, and I didn't want sun in the shot anyway, so that's why I combined shooting both my background and subject in shade with the flash. The flash was set on a stand just out of the frame of the camera, about 7 feet high, pointing slightly down on my subject from camera right. Step 3: meter your background My first step was to take a test shot without the strobe. I set my camera at my standard ISO 100, f8, 1/200 sec. I was using my 5D with 70-200mm f2.8L IS lens. Checking my histogram, this shot was about 2.5 stops underexposed:
This first test shot was too dark. I'm not talking about my subject here (since I hadn't even turned on my flash yet), I'm just referring to the background. So I quickly just changed the ISO from 100 to 200 and the aperture from f8 to f7.1 and zoomed in on the background for this second test shot. ISO 200, f7.1, 1/200 sec.:
Perfect! I've now set up my camera metering so that my background is about 1 stop underexposed, which is the look I was going for. My camera exposure has been set using only 2 test shots which took about 15 seconds total. Step 4: adjust flash power Now that my background exposure has been set, it was time to turn on the flash and test the exposure of my subject. I set my flash to manual mode at full power. Looking at the shot and my histogram, my subject was clipping here, so I knew the flash power was too high.
Adjusting the power down about 1 stop gave me the right exposure on my subject. (yes, there is some shine on my subject's face, but that's not due to overexposure. I would take care of the shine in my retouching process) Here's my final test shot:
Step 5: composition Okay, now my location selection, shot setup, camera exposure and flash power are all set. Time to compose the shot. Don't just point the camera and shoot! Ask yourself what message are you trying to convey with the shot. In this case, I wanted to convey the message that my subject was a competent, confident, yet friendly academic. I started by framing the shot with a fairly standard rule-of-thirds positioning of my subject. The background establishes the fact that she's an academic. I asked her to cross her arms in a relaxed way and smile. Finally, I dropped down to a kneeling position so I could shoot slightly upwards. This did two things: first, it allowed me to get a better, bigger view of the academic building in the background rather than just the bushes at the base of the building. Second, it established my subject in a more powerful, confident position - one that conveys her professional expertise. Lastly, the tree branches on the upper right and the bushes on the lower left create a kind of natural frame to the image. So here's the final image. Remember, this was taken at 1 pm on a blindingly sunny day:
The headshot My client also needed a tight headshot. A headshot has a completely different function than an environmental portrait. The background becomes unimportant. You're not trying to tell a story about your subject, you're just trying to capture their likeness in a favorable way. The background should be as distraction-free as possible. Without moving my subject, all I did was to stand up and frame her head so that the dark bushes instead of the building were in the background. Camera position was about mouth-high, which is fairly standard for a headshot. I also zoomed in to about 150mm, which blurred the background nicely.
That's it! The entire session from the moment I arrived at the scene to taking the final image took about 15 minutes. Just remember the following steps: (1) Location: analyze your location and figure out how you're going to get the appropriate background with a manageable degree of contrast, especially if it's a sunny day. (2) Set your camera to manual mode and meter your background. Depending on the look you're going for, your background might be properly exposed, -1 stop or even -2 stops. My default setting is to meter the background at minus 1. (3) Set up your strobe(s) and adjust them until you have the right exposure on your subject. (4) Compose your shot for the desired effect. A note on sharpening: I'm using a camera (the Canon 5D) that produces very crisp files. I'm using a lens (the Canon 70-200 f2.8L IS) that is tack sharp. I'm lighting my subject's face with perfect exposure. And finally, I'm using an aperture (f7.1) that maximizes the lens sharpness. All this adds up a very sharp image so only minimal sharpening was required. I simply used Photoshop's Smartsharpen filter at very low power - amount 36%, radius 0.8. This was plenty. I'm a big fan of tack sharp images, but remember that your sharpening tool should be a scalpel, not a sledgehammer. |
