Information on how to take the best photographs of your skin lesion or rash.

Use a background

Backgrounds should be plain and dark (if possible) providing no distraction from the area of interest.

To avoid shadows in the photo, place the skin in contact with a background surface Consider using flash as general office or household lighting may not be enough (see images in the PDF below).

Good overhead lighting is ideal.

Take an initial image, followed by a close up

We need three photos of each area of interest:

  1. An image showing the location on the body
  2. A view of the lesion or rash
  3. A close up image of the lesion or worst affected area in the case of a rash

Take more than one image

When taking a photograph, the camera needs to be taken from above and face onto the lesion.

To demonstrate the size and shape of the lesion, you could consider taking additional image views

Auto focus on the lesion

Images must be in focus for the dermatologist to review. Most smartphone cameras have a built-in auto-focus feature. You may need to wait a second for the auto-focus to find the lesion. If your camera is too close to the lesion this usually results in an out of focus photograph.

5 MB is the limit

Consider setting your camera or smartphone image resolution to a lower setting (such as ‘medium’). Most NHS computers have a limit to the file size of any attachment which can be opened in emails to a maximum of 5MB.

Email your photographs to the Dermatology Department at Gloucestershire Hospitals NHS Foundation Trust using the following address:
