Ways To Shoot With A Shallow Depth Of Field - Stop worrying about front-to-back sharpness and embrace a bit of bokeh.
We'll begin by covering the basics of this technique before moving on to shooting suggestions. If you want to take a more in-depth look at this technique, there's several tutorials on ePHOTOzine that cover this subject.
The BasicsSwitch to manual or Aperture Priority as you need to be able to control your aperture. This is something all DSLRs and most advanced compacts, such as the Nikon P7700, will allow you to do. Larger apertures (smaller f numbers) give you a shallower depth of field and help create the blurry, out of focus backgrounds we are after.
Although the main way to control depth of field is with the aperture the positioning of yourself and your subject can also enhance the blur. You want to, ideally, close the distance between the camera and subject but have as much distance as possible between your subject and the background.
Use longer focal lengths rather than wide-angles and use a tripod where possible as the smallest of movements can change the focus and potentially spoil your shot. Using manual focus can help although switching to single-point mode when using auto focus should be fine for most subjects.
If your camera has it, use the depth-of-field preview button as it's a really useful tool to allow you to visualise the amount of sharp focus in a scene. It's a feature found on most, more advanced cameras such as the Nikon D800 and Nikon D600.
Play With Christmas Lights IndoorsWe know it's only November but this is one you can try when you've unpacked the fairy lights from the loft. Ideally you want a camera with a bright aperture, such as an f/1.4 - f/2.0 compact camera, or if you use a mirrorless or Digital SLR it should be easier to achieve the effect.
Drape your lights over a dark background and place your subject or model as far away from it as possible. This will increased blur / bokeh effect in the lights.
Keep the model or subject closer to the camera and adjust your framing depending on where you want the lights and the subject to be lined up / arranged. You may also need to position another light so it highlights your model's face.
We will be covering this technique in more detail later on in the month.
Wider ViewsWhen you think of landscapes, using a shallow depth of field isn't probably something that fist springs to mind. The traditional landscape has front to back sharpness, however having something in your foreground that's perfectly sharp while the scene in the background is thrown out of focus gives the more common landscape shot a creative twist.
Make The Mundane InterestingWith a shallow depth of field a simple blade of grass can look amazing! A blade of grass? We hear you cry. Yes, if you use a shallow enough depth-of-field a blade of grass can look pinsharp and picture perfect against a very blurry background.
You need to use a wide f stop to get the right effect. The aim is to get as much of the subject in focus as possible without losing the nice blurry feel but don't over blur the shot as this will distract from the subject. Try f/5.6 or f/8 and use the camera's depth-of-field preview button to check the aperture's effect on the background. It works great on blades of grass, insects and small flowers. During the summer, if you live near a rapeseed field try isolating a specific flower or part of the field out to draw attention to it. You could try blurring part of the foreground as well as the background to create a frame for the subject.
LandmarksThe problem with landmarks is they are popular photographic subjects but by introducing blur, you can create a shot that not many other people will have taken. Make your chosen landmark completely blur out of focus and find some foreground detail that will stay in-focus and provide enough information to explain to the viewer what the background object is. Take a look at Ben Boswell's article for more tips on how to do this successfully.
Go LongThe Bokeh effect of shooting on a long lens with a wide aperture will turn background lights on city streets into circles of glowing colour, making them a perfect background for portraits. You'll need to stand a few feet away from your subject and do check your white balance to help ensure the lights in the background are glowing the colour they're meant to be.
Change The ShapeYou don't just have to settle for circular out of focus highlights as your can use black card and a pair of scissors to change the shapes that appear. You need to decide on a shape, cut it out of the card then fast the card around your lens like you would a lens hood. Try to not make your shapes too small or complicated as they won't stand out very well in your final shot but ensure they are not bigger than your aperture either.
