Distance to subject refers to the length between the camera and the focus of the image. The closer the camera is to the subject it is focusing on, the narrower the depth of field will be. Inversely, the farther away the subject is from the camera, the wider the depth of field will be.

Infographic illustrates how changing the aperture, the focal length and the distance from the subject affect the depth of field. Download Image  Share Image: X Facebook Email Photo by: DINFOS PAVILION Team VIRIN: 200907-D-PA656-0002

The focal length of the lens determines the image magnification. The wider the lens, the shorter the focal length. This allows you to capture a wider depth of field. The longer or more zoomed in the camera lens, the less depth of field you capture.

The aperture is the opening created by a set of overlapping metal blades, known as the diaphragm, inside a photographic lens. This opening controls the amount of light coming through the lens. The wider the aperture, the less depth of field you capture. The smaller the aperture, the deeper the depth of field.

What isspectrometerused for

Bruker HCT Plus ion-trap mass spectrometer. Sample can be introduced either through direct infusion or by coupling with one of our LC systems (i.e. HP 1100 LC and Agilent 1100 capillary LC).

You can affect the depth of field by changing the following factors: aperture, the focal length and the distance from the subject.

We acknowledge the land on which Brock University was built is the traditional territory of the Haudenosaunee and Anishinaabe peoples, many of whom continue to live and work here today. This territory is covered by the Upper Canada Treaties and is within the land protected by the Dish with One Spoon Wampum agreement. Today this gathering place is home to many First Nations, Metis, and Inuit peoples and acknowledging reminds us that our great standard of living is directly related to the resources and friendship of Indigenous people.

The following graphic illustrates how changing these factors: aperture, focal length and the distance from the subject affect the depth of field.

Depth of field (DoF) is the area between the nearest and farthest points from the camera that are acceptably sharp in an image. A deep DoF means all or most of your photo will be in focus, including the foreground, subject and background. Use a deep DoF in group photos, landscape shots and when elements in the background or foreground add to the message the photo is attempting to communicate. A shallow DoF means more narrow range will be acceptably sharp in the image. Shallow DoF is good to use when you want to isolate your subject from their surroundings, such as in a portrait or when elements in the background or foreground may be distracting.
