Practice management | PrAcTIcE PhoTogrAPhy | Programme mode
Programme mode is represented by a P. This allows the user partial control over both the aperture and shutter. This mode is not necessary for patient photography.
Symbol of person running This mode is typically used for fast moving subjects. It sets the shutter speed to a fast setting and raises the ISo. This mode is not necessary for patient photography.
if the patient is under
18 years, a parent or legal guardian should
be requested to sign
Symbol of mountains Depending on your camera, this mode typically sets your aperture to the smallest setting possible given the available light, and can raise the ISo. Although it may seem unlikely, this mode can be used for capturing subjects in a greater depth of field than other modes.
Symbol of a person’s profile This mode represents portrait mode. Although it may seem like a good mode for capturing the face of a subject, it is not recommended to use this mode as it widens the aperture, putting the background out of focus. For patient photography, it is best to use a small aperture so that all features are in focus.
the photographic consent form for non‑treatment purposes and use.
Symbol of flower (macro mode) It is important to know about macro mode because it can be useful to use in some situations, but it does have its disadvantages. With digital photography, the term largely refers to the camera’s closest focusing distance. The macro mode generally has a flower icon. When this icon is chosen, it tells your camera that you want to focus on a subject closer to your lens5
. Typically, the
macro mode in patient photography is used when the camera needs to be 6 inches or less in distance to the subject. The
disadvantage of macro mode for patient photography is that it typically tells your camera to use a large aperture, which decreases your depth of field.
What to look for in a digital camera There are many objectives to look for when shopping for a digital camera, one of which is the capability of the camera’s zoom. There are typically two types: digital and optical zoom. The digital zoom takes a part of the
scene and interpolates data to fit on the ccD sensor plane. It mimics a greater zoom without actually gaining any additional detail. It often results in a blurry and pixelated image.
The optical zoom changes the amount
of the scene falling on to the ccD sensor. It is preferable to have an optical zoom because the information is not interpolated and can be enlarged and cropped with higher quality results6
. A
3 × optical zoom will give you a focal length of 35–105 mm, which is the minimum necessary for photographing the face and body. There are different types of viewfinders
available on digital cameras. The viewfinder is the window you look through to compose the scene 7
.
Video capability Another important feature to look for when purchasing a camera is whether or not it has video capability. Many consumer cameras come with digital video capability, but some do not. having the capability to shoot digital video on your camera is useful for relaying important information between physicians, patients, and for media presentations.
Flash options There are many options for flash capability on digital cameras. If you are using studio lights with your digital camera, it is important that you purchase a digital SLr that has either a hot shoe or an external flash input connection on the camera. These types of connections allow the user more flash and remote flash synchronisation options.
Consider the patient Patient photography should be performed in a private location, even if it only consists of photographs of the face. Public areas such as open rooms or hallways should be avoided when photographing. Many patients may feel intimidated and embarrassed about being photographed, so ensuring privacy will make the experience more comfortable. Being aware of how your patient feels about the experience and discussing the reasons for taking the photographs with your patient will help make them more at ease, especially
when
documenting more sensitive areas of the body. Allow them to express any concerns they may have
