Many photographers struggle with creating a pure white background in camera, but it is an essential skill that all of us must master. The good news is that it’s relatively easy to do with the right setup. In this article and the accompanying video, I detail my method for creating a pleasing white background on camera.
Two Mistakes to Avoid
There are two common mistakes that you'll want to learn to recognize and avoid. The first mistake is underexposing the background, which results in a sort of dirty-white color or an uneven gradient of white to gray. In most cases, this is going to look bad, whether you are photographing objects or people, because the uneven or unpleasing background becomes a distraction from your subject and does not look professional. The second common mistake is overexposing the background, which is probably worse than underexposing because in this case, the light from the background ends up flaring and enveloping your subject in unwanted light. Therefore, the goal is to get the background lights bright enough that they create an almost pure white while having them set low enough that they don't affect your subject. This also makes the editing process much easier, and, if you are a headshot photographer like me, it gives your clients an accurate representation of what their final images will look like right on the monitor.
A Note on Gear
There are a variety of ways to do this, and it can be accomplished with one strobe directly behind the subject. I prefer using two strobes, one on each side of the subject, because it allows me to take headshots and half- and full-length portraits with the same setup. If you have one light positioned directly behind your subject, you will not be able to take a full-length portrait without moving the light and changing your setup.
Here is the gear that I use:
- Two Alien Bees strobes with reflectors
- Two V-Flat World v-flats
- Savage white seamless paper
- Three Pocket Wizard transmitters (one on the camera and one on each flash)
- TetherTools Pro cable
- Capture One Software
As you can see, we don’t need a ton of equipment to accomplish our task, and whatever brands you prefer to use are fine. The setup itself is relatively simple, but it’s crucial to make sure that everything is positioned properly and that the flashes are at the correct power.
The first step is to make sure you have enough distance between the subject and the backdrop. In my studio, I try to position the subject approximately eight feet from my seamless paper. I recommend placing the subject a minimum of five feet ahead of your backdrop, but if you are working in a very tight space, just make sure they are as far from the paper as possible.
Next, place one strobe on each side of the subject, feathered away from the center of the backdrop. Make sure the strobes are in line with your subject, and not behind them. You will not need the flashes powered very high, so start with them at about 1/16th power. Once we take some test shots, we will be able to dial it in, but remember that small increments in power make a big difference.
Now, take your v-flats with the black side pointed in, and position one on each side of your subject. The v-flats should be tucked in as close as possible to the flash stands. From above, it should create a sort of diamond shape, which is where our client will be placed. Make sure you leave enough room on the interior of the diamond for the subject to stand or sit comfortably and for any modifiers, you might want to place within the shooting area.
Time for Test Shots
Now that we’ve set everything up, it’s time to take a few test shots and make sure our flash levels are dialed in correctly so that we are neither over- nor underexposing our seamless paper. If you are tethered to Capture One, after taking a test shot, scroll your mouse around the entire frame, paying close attention to the RGB levels, which are shown near the top of the screen just below the toolbox. If your RGB levels are above 255, your flashes are powered too high. This will result in a flare from the background enveloping your subject. Generally, I like to keep the values somewhere between 230 and 240, because this will give an almost pure white and eliminate the dirty off-white color. Since we are almost at pure white in-camera, in post, it’s a very simple task to bring it up to pure white while keeping your subject isolated from light spill.
Why Is This so Important?
As I mentioned before, this is a crucial skill for photographers who photograph anything in a studio for many reasons. If you are a headshot and portrait photographer like me, one of the greatest benefits of getting this right in camera (and not relying on Photoshop for heavy lifting), is that your clients can see in real-time what the final image will look like. Showing clients images of a muddy off-white background not only makes it much harder for them to see how great the final product will be but also diminishes the entire image, including the way they are represented in it. In other words, a clean, pure background makes the subject look better too.
Time to Shoot
Now that we have our white background dialed in, we can focus on capturing awesome images. During a typical session, I will turn my Pocket Wizards on and off between a series of captures. With the transmitter on, I get pure white, but with it off, I can also create a pleasing gray color, using the same white seamless paper and without changing anything in my settings or setup. I also have the advantage of taking headshots or portraits by just moving my camera back or changing my lens, which, as I mentioned, cannot be done with one flash directly behind the subject. In the images of jazz sax player Chad above, I was able to take a variety of headshots and portraits without moving anything around, which is a huge advantage.
By providing your clients with a pure white background in camera and with the added benefit of being able to easily shoot headshots and portraits without moving equipment, you will be able to give them a larger variety of awesome images to choose from, making your clients happy and increasing your bottom line.
