If a dermatologist cannot see your skin clearly, they cannot help you. Photo quality is the single biggest variable in whether a remote skin visit produces a useful answer or a request to come back in person. This page is the practical version: what to shoot, how to shoot it, and how to send it.
The short version
- Use natural daylight, no flash, and turn off any warm or colored indoor bulbs.
- Take at least three photos per area: a wide shot for context, a mid-distance shot, and a close-up.
- Include one frame with a metric ruler or a coin next to the lesion for scale.
- Do not apply makeup, lotion, sunscreen, or treatment before photographing.
- Upload only through the platform's patient portal — not by text, email, or social media.
- For changing or atypical lesions, take dated photos over time so you have a record of progression.
Light is the whole game
Every problem with telederm photos comes back to lighting. Bad light hides texture, distorts color, and adds glare. Good light lets a clinician see whether something is red, pink, brown, or violaceous, whether it is flat or raised, and whether the borders are sharp or smudged.
Use daylight, not your kitchen bulb
Stand near a window, ideally during the day, with the light coming from the side or the front. Avoid direct sunlight pointing at the lesion — it blows out detail and casts hard shadows. Overcast daylight is excellent. Most indoor bulbs are warm-toned and shift skin color toward yellow or orange, which is the wrong direction for assessing redness or pigmentation. Turn lamps off rather than mixing them with daylight.
Turn the flash off
Phone flashes blow out the surface of the skin and remove exactly the texture a dermatologist is trying to read. They also produce a glare spot in the center of the image. If the room is too dim without flash, find a brighter room rather than turning the flash on.
Hold the camera steady and let it focus
Tap the subject on a phone screen to set focus. Wait a half-second for autofocus to lock before pressing the shutter. If the shot is blurry on review, retake it; a sharp wide shot is more useful than a blurry close-up.
The three-distance rule
Most asynchronous dermatology platforms ask for at least three photos. Even when they ask for only one, send three.
Wide context shot
Include enough surrounding skin to show where the lesion is on the body. A mole on the back is a different problem from a mole in a chronically sun-exposed area, and the clinician needs to see that context. The wide shot also lets them count lesions if there are several.
Mid-distance shot
Frame the lesion and a few centimeters of surrounding normal skin. This is the single most diagnostically useful angle: borders, color contrast against your normal skin, and whether nearby skin is also affected.
Close-up
Get as close as your phone can focus — on most modern phones, that is a few inches away. Fill most of the frame with the lesion. This is where texture, scaling, crusting, and small structures are visible. If your phone has a macro mode, use it; otherwise just back off slightly until autofocus locks rather than pressing the lens against the skin.
Scale shot
Place a metric ruler, a coin of known size, or any familiar object directly next to the lesion and take one photo at the mid-distance framing. Without scale, there is no way for a remote clinician to tell a 2 mm spot from a 2 cm one. A nickel, a quarter, or a UK 5p will all do; just include something measurable.
Skin prep, before you point the camera
Take photos on clean, dry, untreated skin. Do not apply foundation, concealer, sunscreen, lotion, ointment, or active treatments in the hours before photographing. Topical steroids and prescription creams in particular alter the appearance of inflammation and can mislead the clinician about how active the condition is. If the lesion has crust or dried blood, leave it; do not pick at it for a "better" photo. If hair is covering the area and is not part of the problem, gently part it.
For nail and scalp conditions, clean the area but do not trim or file in the days before. For acne, do not pop, mask, or apply spot treatments before the photos. For a rash that comes and goes, photograph it during a flare rather than during a quiet phase, even if the appointment is days away.
Body areas that need extra care
Face
Take photos with neutral expression, no makeup, hair back, and good front-facing light. For acne, take left, right, and front views. For melasma or pigmentation, daylight near a window matters more than usual because indoor light hides the pattern.
Scalp
Have a second person help. Part the hair to expose the affected area and shoot from above with the part directly under daylight. For diffuse hair loss, include a wide shot of the crown, the part line, and the hairline.
Genital and perianal areas
These are clinically common and the platform almost certainly accepts them through the secure portal. Use a private room, daylight if possible. Frame just the area in question; you do not need to include identifying detail. Some platforms allow flagging a photo as sensitive so it is only viewed by the assigned clinician.
Nails
Photograph each affected nail individually in a close-up. Include one shot of the whole hand or foot for context and for comparison with unaffected nails.
If the condition is changing
For moles or lesions you are watching over time, build a small dated archive. Take the same three-distance series at the same lighting and angle every few weeks or months. Save the photos with the date in the filename. Most patient portals will accept multiple uploads as separate attachments. Visible change in size, color, border, or symmetry is part of the reason a dermatologist may move to in-person evaluation or biopsy. See dermatology remotely for what teledermatology can and cannot resolve.
Sending the photos securely
Upload through the patient portal the platform provides. Do not send dermatology photos by SMS text message, by personal email, by social media direct message, or by any non-portal channel. SMS and consumer email are not HIPAA-secured. The portal exists for a reason: encryption in transit, access logs, and association with the chart.
If a clinic asks you to email photos to a generic clinic address, ask whether they have a secure upload portal first. Most established practices do. Patient-uploaded photos should end up in the chart, where they can be referenced at follow-up visits and shared with other clinicians if you change practices — see transferring medical records. Photos sent by SMS often live only on someone's phone.
Caption every photo
Most portals let you add a short note to each upload. Use it. Useful captions: where on the body the photo shows, when you took it, whether it is the same lesion as a previous photo or a new one, and what is happening at the moment (itching, burning, painless, draining). For a series, label them "wide," "mid," "close," and "scale" so the reviewer can sort them quickly.
What to ask, what to send
- Three photos per lesion at three distances, plus one with a scale reference.
- The date each photo was taken, written in the caption.
- A short symptom history: when it started, whether it itches or hurts, what makes it better or worse.
- A list of any treatments already tried, including over-the-counter ones.
- Other photos for context — for example, photos of unaffected sides for comparison.
- Any prior dermatology notes, biopsy results, or pathology reports you have.
When this is not enough
Some skin problems cannot be safely managed by photo. A full-body skin check for cancer screening cannot be done remotely; a dermatologist needs to see the entire skin surface, including areas patients rarely photograph well, such as the scalp, the soles, and the back. A lesion that has changed quickly, that bleeds without provocation, that looks different from your other moles, or that the clinician calls "atypical" needs in-person evaluation and almost always a biopsy. Anything resembling a skin emergency — rapidly spreading redness with fever, a painful purple rash, a new blistering rash with mouth or eye involvement — is an in-person or emergency department visit, not a photo upload.
