In short. Clinical photographs for a remote consultation have one job: to show the clinician what is there as accurately as possible. Angles, lighting and a scale reference decide whether an image can be read, and a flattering photograph is a bad clinical photograph because it hides the texture, colour and border that need to be seen.
Key points
- A clinical photograph should show what is there, not what looks best.
- Send a small set: straight on, each side, and above and below.
- Use even, diffuse daylight and face the light source.
- Put a ruler or coin beside the area, in the same plane as the skin.
- A dated series shows change over time; an undated set does not.
What a clinical photograph has to do
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.
Which angles should you send?
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.
What lighting makes an image readable?
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.
Why a scale reference matters
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.
How a photograph loses its clinical value
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.
| What to avoid | What it hides | What to do instead | Why it matters |
|---|---|---|---|
| A filter or editing | Texture and colour unevenness | Send the image unedited | The clinician cannot see what was removed |
| A flattering angle | Shadow and asymmetry | Straight on, plus each side and above and below | A finding reads differently from a favourable view |
| Direct sun | Colour, behind hard shadows | Face even, diffuse daylight | Shadows exaggerate texture |
| Indoor lamps | True colour, with hotspots | Face a window and turn the overhead light off | Colour is part of the finding |
| Phone flash | Surface detail | Use daylight instead | Flash flattens and washes out the surface |
| A tight crop | Context around the lesion | Include the whole region | Context changes how a finding reads |
| An undated set | Change over time | Say when each image was taken | A dated series shows change; an undated set does not |
How should video be recorded?
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.
Images that should not be sent
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.
When is a description better than a photograph?
Say so instead if you cannot take a clear image and are tempted to send a poor one rather than describing what you see. Say so if the only photographs you have are old, flattering, or taken from a different angle to the area in question. Say so if you are unsure whether an image shows the problem at all. A clinician can only work with what they are shown, and an incomplete picture produces advice that does not fit your actual situation.

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.
