The aperture, represented by f-stops (f/1.8, f/4, f/8, etc.), is the opening of the camera lens that controls the amount of light reaching the sensor. A wide aperture (low f-number) lets in more light, while a narrow aperture (high f-number) allows less light in.

Last but not least, combine all the captured images using post-processing software (Photoshop or something more specialized). The software will analyze each image’s sharpest areas and merge them into one final composite image where everything appears in clear focus.

Whether to choose a deep or shallow depth of field depends on what you’re trying to achieve with your photo. The same scene can be effectively captured with diverse DOF settings – as long as you know how to work the camera lens in your favor!

To clarify, the technical DOF (area of sharpness) remains identical regardless of the sensor size. Nevertheless, the image might appear to have a different DOF due to the sensor size affecting the field of view.

When working with extreme close-up shots in macro photography, even slight changes in focusing distance can significantly alter the DOF. Hence, many professionals consider using stacking techniques to achieve overall sharpness; we will return to it later.

Let’s say you are photographing a landscape where you want both the foreground wildflowers and the distant mountains to appear sharp. A single image captured at a specific aperture might leave either the foreground or background slightly out of focus. What should you do?

Your camera lens might capture the entire scene, but that does not mean every part turns out equally sharp. How you focus your shot can make or break the shoot’s outcome, and that’s why understanding depth of field definition is important. Keep scrolling to learn more!

On the other hand, a deep DOF keeps certain foreground and background parts sharp using a wider aperture (e.g., f1.4). Landscape photographers benefit the most from this approach, as they must capture the vastness of the scene without compromising crisp details in both near and far elements.

A shallow DOF, for example, creates a dreamlike, more intimate feel, blurring the background to draw the viewer’s attention directly to the subject in sharp focus. This technique is commonly used in portraiture or product photography and small apertures (e.g., f11).

In traditional photography, a single image has a limited DOF. Depending on your aperture setting, only a specific area around your focus point will be perfectly sharp, and elements closer or farther away will appear progressively more blurred.

But no worries; focus stacking is the solution! As the name suggests, this technique captures sets of images of the same scene, each with a slightly different focus point.

Suppose you want to photograph a tiny spider on a dew-covered leaf, isolating the spider and its intricate details to create a sense of mystery. In that case, extremely shallow DOF (f/2.8 to f/6) would be ideal, as it ensures only a small area around the spider is sharp. The background leaf and surrounding elements blur significantly.

A mid-range aperture (f/5.6 – f/8) strikes a good balance between DOF and light gathering: You get a more noticeable area of sharpness around the focus point, with some background blur. This versatile option works great for various photography styles, like portraits with some context (refer to our examples above) or landscape photography with a defined subject.

In simple terms, it’s similar to cutting a thin slice through your image; everything within that slice appears sharp while the rest blurs progressively. The thickness of this slice determines your “depth of field.”

A narrow aperture (f/11 – f/16 and above) brings in a deeper DOF to put almost everything in focus, from the foreground to the background.

On the contrary, short but wide focal lengths (like wide-angle lenses) tend to produce a deeper DOF at the same aperture compared to telephoto lenses. Due to the wider field of view, the photo’s elements now seem further apart in the frame, even at close focusing distances.

You can start focusing on the closest element in the scene and then progressively shift the focus point further back with each image, ensuring some overlap between areas of focus in consecutive shots. The number of pictures needed can vary depending on the depth of the scene.

Regarding option 2, a variable DOF (f/5.6 to f/8) maintains some sharpness in the background, perhaps including a landmark or building that adds context to the portrait’s location. This creates a more balanced image in which both your friend and some of the environment are in great focus.

Contrary to popular belief, shutter speed does not directly affect DOF because it controls a different aspect of your image: exposure. Specifically, it controls how long the camera’s sensor remains exposed to light: a fast shutter speed lets in less light, while a slow shutter speed means more light reaches the sensor.

Depth of field (DOF) refers to the distance between the nearest and furthest objects in a photograph that looks acceptably sharp. This crucial concept affects how you draw attention to your subject and creates a sense of focus within the frame.

First, set up your camera; we suggest using a tripod so your camera remains perfectly still throughout the entire image capture process. Switch your lens to manual focus mode to have complete control over the focus point for each image.

Longer focal lengths (e.g., telephoto lenses) naturally have a shallower depth of field compared to wider lenses at the same aperture setting. The reason is simple: since the background is compressed, elements appear closer together and intensify the blur at a given aperture.

Let’s say you and your friend are capturing the exact same flower field with identical camera settings and viewing distances – except you use a full-frame camera and your friend uses an APS-C camera:

This issue also applies to street photography to a certain extent; given the candid nature of the captured moments, photographers do not always have control over the distance to their subject. Nevertheless, understanding how distance and DOF work together can help them anticipate the blur effect and use it effectively to frame the subject within the vibrant street scene.

In that case, DOF bracketing allows you to review and assess which aperture setting produced the most desirable balance. The diverse variations of the same scene (with different apertures) also give you more options for post-processing later on.

These lasers are primarily used for periodontal treatments. Their proclivity for pigmented tissue allows for effective debridement and disinfection of periodontal pockets. Bacterial decontamination in tissues treated with Nd:YAG laser energy also contributes to resolution of periodontal infection. As noted earlier they stimulate fibrin formation with longer pulse duration settings and this phenomenon is utilized to biologically seal treated pockets and act as a scaffold for reattachment. The ability to form fibrin is also utilized when forming clots in extraction sites which can help prevent alveolitis and enhance osteogenesis. Nd:YAG lasers can also be used for multiple soft tissue procedures such as gingivectomy, frenectomy, impression troughing, and biopsy. The deep penetration and the near infrared wavelength of these lasers also make them ideal for photobiomodulation procedures.

Nd:YAG lasers were the first types of true pulsed lasers to be marketed exclusively for dental use in 1990. They are a near infrared wavelength of 1064 nm. This wavelength is absorbed by pigment in the tissue, primarily hemoglobin and melanin. Photothermal interaction predominates and the laser energy can penetrate deeply into tissues. Contact and non-contact mode are both utilized depending on the procedure being performed. Nd:YAG also have excellent biostimulative properties. Nd:YAG lasers have the unique capacity to safely coagulate blood, a phenomenon used postoperatively with extractions and soft tissue procedures. . This effect is maximized when the pulse duration is set at 650 microseconds.

This can pose quite a challenge in situations where you want everything in the scene to be crisp and detailed, such as when photographing tiny insects or intricate details of flower petals.

Let’s say you are a portrait photographer taking a picture of your friend against a busy cityscape backdrop. You are pondering two options: (1) make your friend the center of attention by blurring the cityscape background, or (2) include some environmental context while still keeping your friend sharp.

Suppose you were photographing a landscape and wanted a deep DOF to capture everything sharp. In that case, you might choose a narrower aperture (higher f-number) and faster shutter speed (if it’s a bright scene) without affecting the exposure or the DOF you’ve selected with the aperture setting.

For option 1, a narrow depth of field (f/1.8 to f/4) creates a strong separation between your friend and the background, drawing all focus to their face and expression. The blurred background becomes almost abstract and visually less distracting.

Sometimes referred to as aperture bracketing, DOF bracketing captures multiple images of the same scene with slightly different aperture settings (this is different from focus stacking, which adjusts focus distances).

In this episode of Crash Course Biology, we'll discover how we see what we can't see, thanks to the help of centuries-old tools and more recent technology.

As you move closer to your subject, the depth of focus becomes shallower, meaning the subject looks sharper and more isolated from the background. On the contrary, a further distance at the same aperture will deepen the DOF and allow a larger portion of the scene into acceptable focus.
