How do you take good dermatology pictures?
The basic principle of dermoscopy is transillumination of a lesion in order to study it with high magnification to visualize subtle features.
Light incident on a surface like the skin may be reflected, refracted, diffracted and/or absorbed [Figure 1A].
The physical properties of the skin influence these phenomena.What is the technique of dermoscopy?
Handheld dermatoscopes usually allow a 10-fold magnification, which is usually satisfactory for the daily practice.
In addition, lower magnifications have the benefit of providing a better overview of a large scalp area.
Do not go beyond the autofocus of the camera to avoid image blurring. Autofocus on the lesion and then use the zoom to get closer to the lesion of interest rather than moving the camera closer, to enable even lighting from the flash. If the lesion is small the camera may not focus that close.
