If the picture looks like what you are seeing in person, you have a good picture.

No distractions, just the skin problem (jewelry, bright clothing or furniture, toys, pets).

Focus the camera on the skin problem, usually by tapping on the screen (not the carpet, or other background)

The skin problem should face the light, ideally natural light, either outside or go to a window.

If inside, the person taking picture should be between the patient and the window.

Do NOT use filters on any type of smartphone or portrait mode on iPhone.

Use a neutral background, such as a single color wall or sheet.

Try to get some normal skin in the photo for comparison.

Try not to have a shadow from the camera itself.

Keep the camera perpendicular/straight to the patient (not angled back or forward).

Keep the person at straight angles (horizontal or vertical) to the camera.

Tap on the brightest area of the area of the rash or bump that you are photographing.

Avoid using flash (if you have good light).

On a smartphone, zoom by “pinching” in or out on the screen.

On a smartphone, zooming in beyond the halfway point will distort the image. It is better to move closer and zoom less. Just remember to re-focus.
