Portrait Background


Portrait Background Basics

Four ways to flatter your subjects with a pleasing visual environment


1 Find a simple background


One of the most important things you can do to make better portraits is to find, or create, a background free of distraction. This doesn't mean your backgrounds have to be plain, especially if you're shooting an environmental portrait where context is key. But, generally, you want to find a setting that focuses attention on your subject with minimal visual clutter. Here are some essential tips to ensure that your model—and not the background—is the center of attention.


  • 1 FIND A SIMPLE BACKGROUND
There's a reason why portrait studios have roll upon roll of neutral backdrops—they don't distract from the subject and they're relatively easy to light. Most of us don't have the room for a dedicated photo studio, so we have to be more creative.

For a studio look at home, a blank wall, closed window curtains or even a bed sheet taped to the ceiling all can provide a clean backdrop for your image. You can use a single light placed behind your subject to illuminate the background and create a sense of space and depth. If you're working with on-camera flash, try bouncing it off of the ceiling for softer, more diffused light.

When shooting outdoors, look for a large wall or a garage door (alleys at midday are a good place to start), or an open vista where you can use the sky as your background.



2 Reduce your depth of field
  • 2 REDUCE YOUR DEPTH OF FIELD
Using a large aperture for shallow depth of field not only will help create a pleasing, soft background, but it can let you be creative with out-of-focus foreground elements, too.

Be careful, though! With a shallow depth of field, it's especially critical to be sure that your subject's facial features are in focus, so try manual focusing. Review images on your camera's LCD preview to zoom in on facial details and check that they're sharp.


Or consider exposure bracketing with multiple apertures; it's safer than finding that your favorite shots are slightly out of focus when you view them on a larger screen. Though a pleasing background is important, focus is fundamental.


                                                            3 Use a telephoto lens
  • 3 USE A TELEPHOTO LENS
Telephoto lenses can help eliminate background distractions by cropping out most of the surroundings and allowing your subject to dominate the frame. Depth of field also decreases as focal length increases, softening the background.

Another benefit of telephoto lenses is that they "compress" the perspective, making objects closer to the lens appear smaller relative to objects farther from the lens. In portrait photography, this has the often pleasing effect of reducing the prominence of your subject's nose and reducing the "nose-to-ear" distance. A telephoto lens also allows you to work at a comfortable distance from your model. Telephoto zooms give you compositional flexibility, too.




  • 4 TRY SOFTWARE EFFECTS
Though it's always preferable to get the shot as close to perfect as possible with your camera and lens, you have options for cleaning up your backgrounds with software. Though this means more computer work—and things can look weird if you're not careful—software can help when you captured the perfect expression in a less than perfect environment. If you have skill with masking in Photoshop, you might apply a soft blur to the background manually; or there are excellent software plug-ins dedicated to creating more pleasing portrait backgrounds.

Try these tips—by themselves or working together—for subject-flattering, pro-quality portraits.

One-Light Portraits how to...

One-Light Portraits

Cool lighting techniques using a single light source





In portraiture, there's a temptation for some photographers to use several lights, with the goal of creating a dramatic portrait. That can work, for sure. On the other hand, using only one light also can produce some awesome portraits. What's more, it's much easier to work with one light than with two or three lights.

In this article, we'll explore some one-light techniques. I used a Canon Speedlite 580EX II in a Westcott Apollo softbox for these shots. I shot on E-TTL, the automatic exposure mode on Canon Speedlites, and fine-tuned my exposure using the +/- control on the Speedlite. The Speedlite was triggered by a PocketWizard radio controller, which consists of a shoe-mounted transmitter and a Speedlite-mounted receiver.

You can create similar effects if you shoot using a constant light source in a softbox. I specifically mention and recommend using a softbox for portraits because an umbrella spreads the light, while a softbox, with a recessed diffusion panel, lets you direct the light. Umbrellas are good for group shots and for portraits with less dramatic shadows.

When it comes to shadows: Shadows are the soul of the photograph. Shadows add a sense of depth and dimension to a photograph. Shadows are your friend.

Before we get going, here's the main thing to remember about using any type of light: The larger the light, the softer the light; the closer the light, the softer the light. In portraiture, you usually want soft and flattering lighting.




1 | I used my one-light setup for the opening photograph in this article. I had a "voice-activated light stand" (my friend Kathy Porupski) hold the softbox directly over the subject. When you use this technique, keep two things in mind: One, make sure the speedlight is securely fastened in the softbox—you don't want it falling out and hitting the model on the head. Two, as you move the light toward the camera, you'll light more of the subject's face, and vice versa.


2 | After I took my shot of the model positioned on the floor, I played with my image in Photoshop for a different look.
First, I rotated the image counterclockwise. I used the Paintbrush tool (black selected) on the lenses of the sunglasses to remove the reflection of the softbox. I like the reflection, but here I was going for a different look. And, finally, I used the Dynamic Skin Softener filter in Nik Color Efex Pro to soften the model's complexion.







3 | Here's an example of what happens when you position the light slightly behind the subject. As you can see, less of the face is illuminated. Plus, you get a cool rim-light effect.

4 | Another cool technique is to create a silhouette. Simply point the light at the background and make sure no light illuminates the subject. You can do this by shooting at a low ISO, a fast shutter speed (not higher than the max sync speed of your camera, usually around 1⁄200 sec.) and a small aperture. Use these settings and take a shot without the flash turned on. If your picture is totally black, you have the correct exposure settings—because you don't want any room light illuminating your subject. Now, turn on the flash and fire away. You'll get the best silhouette, and you'll be able to recognize the person if he or she is facing directly to the right or left.


5 | Here's another example of lighting the background. I used a white background and placed a red Honl gel over the speedlight. For the shot of the man with a hat, I placed a blue Honl gel over the speedlight.



6 | Of course, you can take less dramatic, but still attractive portraits with a basic one-light setup, as illustrated by this photograph.
Yes, the background looks as though it's illuminated. That's because it's a brightly painted background, painted to look like a sunset.

For this photo, a reflector is being held opposite the softbox to fill in some of the shadows caused by the one-light setup. So, in reality, there are two light sources—but still only one main light. In this photograph, you can easily see the recessed diffuser panel in the softbox.

7 | Here's another one-light portrait. It's soft because the softbox is placed near the subject and because the light is what's called "feathered." When you "feather" the light, you don't aim the light directly at the subject. Rather, you aim it slightly in front of the subject.




8 | Here's a cool technique for "lighting up" a black background.
Try using the Lens Flare filter in Photoshop. That's what I did here to create an image in which the girl looks as though she was photographed on a stage.




9 | Here's yet another shot using my one-light setup. When shooting with a speedlight outdoors, use the shutter speed to control the brightness of the background: The higher the shutter speed, the darker the background, and vice versa. Adjust the output from your speedlight with the +/- control on your speedlight or in your camera. Using this technique, you can control the subject brightness and background brightness independently. How cool is that?



10 | One final thought: Experiment and have fun with the light! Move the light around and move around to see how changing position by a few feet, and even sometimes a few inches, can change the shadows in your photograph.





Digital Scene Modes tips


All About Scene Modes

Harness the power of your camera's scene modes to make better pictures in any circumstances




MACRO/CLOSE-UP MODE

Your camera's Scene modes are for amateurs, right? Not really. Scene modes can be great shortcuts that allow even professionals to make some powerful changes with the flip of a single switch. Here's what happens behind the scenes of each mode, and how you can put them to use in your own pictures.






PORTRAIT MODE
  • PORTRAIT MODE
When you set your camera to Portrait mode, it automatically chooses a wide aperture (like ƒ/2 or ƒ/2.8) to create a shallow depth of field. This helps to isolate your subject, visually separating him or her from the background. The closer you get to your subject, the more noticeable the effect will be, so stand just a few feet from your subject and fill the frame with his or her head and shoulders.

To strengthen the effect, set your lens to a longer telephoto setting and keep an eye on the background, choosing something simple as a backdrop to minimize distractions. Some cameras also utilize face-detection focusing in Portrait mode, and enable red-eye-reducing fill-flash and a subtle softening effect for pleasing skin tones.



  • SPORTS MODE

SPORTS MODE

Sports mode is built for capturing fast action. To that end, the camera will select its fastest available shutter speed and may increase the ISO to accomplish this. The aperture is likely to open up and create a shallower depth of field, which could become an issue with a fast-moving subject.

Because of the high shutter speed, the camera won't use a flash, and if it has the capability, it will utilize continuous focus-tracking and high-speed shooting so you can fire off several frames in a row.

The best way to photograph a fast-moving subject (like a runner or a cyclist) is to pan the camera with the motion as the subject crosses the frame. If you'd like to minimize the speed of that movement, position yourself so the action is moving toward the camera or away from it, rather than laterally across the scene.



  • MACRO/CLOSE-UP MODE
Use Macro mode for shooting small subjects (like insects and flowers) or for close-up details. On some point-and-shoot cameras with motorized zooms, this mode will spur the camera to automatically choose the focal length at which it can focus closest.


Hand holding for macro shots can be tricky, as the slightest movement can mean the difference between a subject in totally sharp focus and one that's blurry. Try to use your camera on a tripod, or at the very least position yourself so you can brace the handheld camera against another object. Depth of field can be microscopic in macro, so maintaining a steady composition is crucial. Flash is usually set to automatic, so it will fire if needed and compensate for being so close to the subject.






LANDSCAPE MODE
  • LANDSCAPE MODE
Landscape mode is the polar opposite of Portrait mode. With the lens focused at infinity, instead of choosing a wide aperture to create a shallow depth of field, Landscape mode prompts the camera to choose a small aperture (such as ƒ/16 or ƒ/22) to increase depth of field so that all elements of a landscape, from foreground to background, will be in focus.

To accomplish this, the camera is likely going to have to use a slower shutter speed, especially if you're working in low light. To prevent blur, a tripod is an ideal accessory for Landscape mode.

The flash is also disabled because the camera assumes you're photographing something at a distance. In some cases, saturation is boosted subtly for more vibrant foliage, although this can be separated out into its own mode.


  • NIGHT PORTRAIT


NIGHT PORTRAIT

If there's one Scene mode that should be on everyone's radar, it's Night Portrait. This mode uses a combination of a long shutter speed and fill-flash, sometimes referred to as "dragging the shutter."

The premise is simple: If you're photographing a portrait in low light, the long ambient exposure will allow the background to register on the sensor, while the fill-flash will illuminate the subject. That combination is a real showstopper, as it prevents the dreaded "brightly lit subject standing in front of a pure black background," just as it avoids a blurry foreground subject that would result from a long exposure for the background.

Ever notice at a sporting event or concert all those flashes in the stands? If those photographers were making portraits with Night Portrait mode, they'd have nicely lit foreground subjects and a brightly illuminated playing field or stage in the background.


Use a tripod to get a background in sharp focus. For a bit of artistic blur, handhold and move the camera. If your camera has face-detection technology, enable it in order to focus on the subject rather than the background.




  • EVEN MORE MODES
The five Scene modes listed here are by far the most common, and they're likely to be found on most cameras. But your camera also may include additional Scene modes to tackle even trickier situations.

SNOW/BEACH MODE enables exposure compensation (usually +1 stop) to prevent the underexposure that frequently occurs in these extra-bright outdoor environments.

PARTY MODE is subtly different than Night Portrait in that it won't use such a slow shutter speed and it doesn't utilize face-detection focusing (if available). Instead, it defaults to automatic flash instead of slow-speed synch.

FIREWORKS MODE works similar to Landscape mode, but it defaults to a long shutter speed, usually a couple of seconds, in order to allow the bursts of light to register as beautiful streaks on the sensor.

NIGHT LANDSCAPE MODE is a whole lot like Fireworks mode in that the camera defaults to long shutter speeds and no flash, both necessary for low-light imagery. Both also require a tripod.




                              ----------------------------------------------------------------------------




CHOOSE THE "WRONG" MODE FOR THE RIGHT EFFECT
Just because a mode is intended for one thing doesn't mean you can't use it for another.

If you want to photograph sports, you might consider choosing Portrait mode. Because of its wide aperture, the camera will be forced to use a fast shutter speed, which happens to be perfect for freezing fast-moving action.

You can harness the power of Night Portrait mode even in brighter light or when shooting indoors. It's a great way to treat the flash as a fill with plenty of ambient light creating the bulk of the exposure.

Food mode is a shortcut to macro shooting without a flash, which makes it perfect for situations in which you want close-ups comprised solely of ambient light—even if it isn't edible.

A great way to make beautiful portraits in soft ambient light is to go high-key. This eliminates blemishes and other skin details. Snow/Beach mode is a great way to ensure a high-key portrait.

Even if it's nowhere near the Fourth of July, you can use Fireworks mode to create gorgeous long exposures where motion blur would be beneficial—such as when water or wildlife is moving in a landscape.

If you'd care to create artistic blurs for creative effect, consider many of the long exposure modes—Fireworks, Landscape, Night Landscape or even Night Portrait—to employ a longer shutter speed that, when combined with a moving camera, can create some pretty cool motion-blur effects.


PANORAMA/STITCHING MODE is unique in that it doesn't use special settings (with the exception of turning off the flash), but it will provide alignment guides or an overlay to assist in alignment of subsequent exposures to stitch together a panorama.

FOOD MODE is a lot like Macro mode, but with the flash disabled so food looks appetizing lit strictly by ambient light.

PETS/KIDS MODE defaults to a fast shutter speed (much like Sports mode) to keep those fast-moving children and pets in sharp focus, but with a camera with face-detecting autofocus, this mode also will fire off a couple of quick shots as soon as it detects focus on a child's or pet's face.






                             ----------------------------------------------------------------------------



GETTING STARTED IN VIDEO MODE
They say everybody wants to direct. Maybe that's why almost every digital camera also features a Movie mode for capturing video. Here are a few tips for getting started with your camera's Movie mode.

1 | Depending on the camera, your high-definition resolution options may be limited to 720p, or they also may include the higher-resolution 1080 option. If you're really trying to maximize quality, choose 1080. But if you just want to be sure you have a nice video to share on Facebook or YouTube, 720 is more than enough. (Either way, you probably want to step up from standard def or VGA.)

2 | Frame rates—which represent how frequently the image in a video is refreshed— likely aren't going to make or break the average user's video, but your choices are usually 24 or 30, or maybe even 48 or 60. The higher the better, theoretically, as a 60 fps rate creates a video with twice as many frames as one with 30 frames per second. If your camera allows you to choose from "p" or "i", as in 1080p or 1080i, you'll probably want to choose "p". It stands for progressive, rather than interlaced, and is generally deemed to create a higher-quality, more seamless finished video, especially with fast-moving subjects.

3 | Your camera may give you some autofocus options as well, since focusing video can be kind of tricky. The single-focus approach will focus once at the beginning of a recording and that's it, while continuous autofocus will keep refocusing the scene throughout recording.

If you have the camera locked down to a tripod and your subject is sitting or standing still, you should be happy with single focus. This way, your camera won't be trying to refocus unnecessarily throughout the recording. But if your subject is a tricky one, moving throughout the composition during filming, you may be better off choosing continuous AF.

4 | With your camera in manual exposure mode, you'd better make sure you have your exposure correct before you start shooting video. Alternately, you can select an auto-exposure mode so the camera will adjust the exposure appropriately throughout recording. This is helpful if you'll be encountering changing lighting scenarios throughout the shot, but it also could be distracting if the camera compensates for subtle lighting changes that cause the iris to open and close.

An alternative, on some cameras, is to use the exposure-lock button to gain the benefit of an initial auto exposure, but then the stability of a constant exposure during recording.

5 | If you'll be handholding your camera while shooting video, consider keeping your zoom lens at its widest position to help mask any of the normal vibrations from handholding. Locking the camera to a tripod for stability will make telephoto shooting much more feasible—and will help keep viewers of the finished product from suffering the effects of motion sickness.
