What Photos to Take for a Skin Assessment
By dermatrix.life Editorial ·
An AI skin assessment is only ever as good as the photos you give it. The model can't ask you to "tilt toward the window" or "hold still" — so a couple of minutes spent getting the shot right makes a real difference to how useful your result is.
The good news: you don't need anything fancy. A phone camera and decent light will do. Here's how to get a photo worth assessing.
Why the photo matters so much
When you upload a picture, that image is the information. Lighting, focus, and framing decide how much the model can actually see. A sharp, well-lit close-up gives it real detail to work with; a dark, blurry one leaves it guessing. This is true of dermatologists looking at photos too — it's not an AI quirk, it's just how images work.
Get the lighting right
- Use soft, even, natural light. Daylight near a window is ideal.
- Face the light, don't sit in front of it. Light should fall on the area, not behind it (which throws it into shadow).
- Avoid harsh overhead or direct flash. Flash flattens texture and washes out colour — two things that matter for skin.
- Watch for colour casts. Yellow indoor bulbs can shift how the skin looks; natural light keeps colours truer.
Focus, distance, and steadiness
- Tap to focus on the exact spot before you shoot.
- Hold steady — brace your elbow or rest the phone against something.
- Get close, but not too close. Fill the frame with the area without crossing into the blurry macro range. If it won't focus, back off a few centimetres.
- Take a couple and pick the sharpest. It costs nothing.
Capture the right angles
- One clear close-up of the area in question, straight on.
- One or two wider shots showing where it is on your body — context helps the assessment understand size and location.
- If something has texture or is raised, a slightly angled shot can show that better than a flat-on one.
A note on skin tone
Skin conditions can look very different across skin tones, and many imaging tools have historically underperformed on darker skin. Honest, accurate colour helps here: shoot in good natural light, skip heavy filters, and don't edit the photo. The truer the image, the fairer the read.
What to avoid
- Filters, beauty modes, or any editing — they change the very details that matter.
- Makeup or creams over the area, if you can help it.
- Extreme close-ups that blur, or distant shots where the area is tiny.
- Cluttered, distracting backgrounds.
Your photos stay private
Taking clear photos means trusting where they go. With dermatrix.life, images are uploaded over an encrypted connection to a private bucket, used only to generate your assessment, and deleted within 24 hours. No human reviews them, your account is anonymous, and nothing is sold. If you want the full picture of how this works, see how AI skin analysis works.
Ready when you are
Once you've got a clear, well-lit shot, the rest takes just a few minutes.
Common questions
Do I need a special camera?
No. A modern phone camera is more than enough. Good lighting and a steady, in-focus shot matter far more than megapixels.
How many photos should I take?
Usually a few — one clear close-up of the area and one or two from slightly further back for context. The intake guides you through what it needs.
Will anyone see my photos?
No human reviews them. They are uploaded encrypted, used only to generate your assessment, and deleted within 24 hours.
What if my photo is blurry or badly lit?
Retake it. A clear photo is the single biggest thing you control — a blurry or shadowed image gives any assessment, human or AI, far less to work with.
