In short. Angles, lighting and scale references decide whether a photograph can be read. A flattering photograph is a bad clinical photograph, and it hides exactly what needs to be seen.
Key points
- Good lighting, a favourable angle and a filter all hide exactly what a clinician needs: texture, colour unevenness, shadow, asymmetry and the true border of a lesion.
- An image that makes you look well is an image that has removed the clinical information.
A clinical photograph has one job: to show a clinician what is there as accurately as possible. A flattering photograph fails at that job, and it fails in a way that can mislead in either direction. Taking images that are useful is a small skill, and it takes a few minutes.
Angles
Send a small set rather than one picture. A straight-on view, a view from each side, and a view from above and below where the area allows it. Include the whole region rather than only the spot you are worried about, because context changes how a finding reads. For anything on the face, a straight-on view at rest and one in the expression that shows the problem are more useful together than several versions of the same angle.
Lighting
Use even, diffuse daylight and face the light source. Direct sun creates hard shadows that exaggerate texture and hide colour. Indoor lamps shift colour and create hotspots. The flash on a phone flattens detail and washes out the surface. If you are indoors, stand facing a window and turn the overhead light off.
Scale references
Place a ruler or a coin beside the area, in the same plane as the skin rather than in front of it, so that a clinician can judge size without guessing. A reference sitting closer to the camera than the skin makes everything look larger than it is. If you have nothing to hand, say so rather than implying a scale that is not there.
Why a flattering photograph is a bad clinical photograph
Good lighting, a favourable angle and a filter all hide exactly what a clinician needs: texture, colour unevenness, shadow, asymmetry and the true border of a lesion. An image that makes you look well is an image that has removed the clinical information.
Video
Short video helps with anything that moves or changes with expression. Keep it steady, well lit, and no longer than it needs to be. Show the area at rest first, then in movement. Do not magnify or edit. A brief, unedited clip of a scar under tension tells a clinician more than a dozen stills.
What not to send
Do not send images edited, cropped tightly, or taken years apart without dates. Do not send a photograph of a screen showing another photograph. Say when each image was taken, because a dated series shows change over time and an undated set does not.
Say so instead if
- You cannot take a clear image, and are tempted to send a poor one rather than describing what you see.
- The only photographs you have are old, flattering, or taken from a different angle to the area in question.
- You are unsure whether an image shows the problem at all.
A note on honesty
Send the images that show the problem as it is, not as you would prefer it to look. A clinician can only work with what they are shown, and an incomplete picture produces advice that does not fit your actual situation.
Frequently asked questions
What angles should I send for a clinical photograph?
Send a small set rather than one picture: a straight-on view, a view from each side, and a view from above and below where the area allows it. Include the whole region rather than only the spot you are worried about, because context changes how a finding reads.
What lighting should I use for clinical images?
Use even, diffuse daylight and face the light source. Direct sun creates hard shadows that exaggerate texture and hide colour, indoor lamps shift colour and create hotspots, and the flash on a phone flattens detail and washes out the surface. Indoors, stand facing a window and turn the overhead light off.

Risks & Limitations
- A remote opinion is not a diagnosis. It is advice based on your account and the images you send, and it does not replace an examination.
- Photographs can mislead in both directions — they can make something harmless look concerning, and something concerning look harmless.
- Important findings can be missed without examination. Measurement, depth, texture and laxity cannot be assessed through a screen.
- A remote consultation must never delay urgent in-person care. If something is urgent, seek care rather than waiting for an appointment.
When to Seek Care
- Difficulty breathing or chest pain — seek emergency care immediately.
- A sudden change in vision.
- Severe pain out of proportion to what is visible.
- Skin turning white, grey, mottled or dusky.
- A lesion that is growing rapidly or bleeding.
- A wound that is not healing.
