Take Better Skin Photos: Tips for Getting Accurate AI Analysis Results

Free checklist for mole, rash, and skin cancer photos

January 20267 min read

Whether you're using AI screening tools or sending photos to a dermatologist, photo quality directly affects accuracy. A blurry or poorly-lit image can lead to missed details or inconclusive results. Follow these simple guidelines to capture the best possible skin photos.

Essential Equipment

Smartphone camera

Any modern phone works—no special equipment needed

Ruler or coin

For size reference (helps track changes over time)

Clean lens

Wipe your camera lens for clear, sharp images

Lighting Tips

Good lighting is the most important factor for clear skin photos.

Natural daylight near a window
Direct flash (washes out details)
Even, diffused light
Harsh overhead lighting
No shadows on the spot
Strong shadows across the skin

Camera Positioning

1

Hold camera 4-6 inches away

Close enough for detail, far enough to include context

2

Position perpendicular to the skin

Angle directly at the spot, not at an angle

3

Include surrounding skin

This helps AI assess contrast and context

Focus and Clarity

  • Tap to focus on the spot before taking the photo
  • Hold steady—brace your arm against something if needed
  • Take multiple shots—review and pick the clearest one

What to Include in Your Photo

  • The spot clearly visible and in focus
  • A scale reference (ruler or coin) in at least one photo
  • Some surrounding normal skin for context
  • Clean skin (no makeup, cream, or blood on the spot)

Quick Reference: Do's and Don'ts

Do

  • Use natural daylight when possible
  • Hold camera 4-6 inches away
  • Include a ruler or coin for scale
  • Tap to focus on the spot
  • Take multiple photos
  • Include surrounding skin for context
  • Keep the camera steady

Don't

  • Use flash directly on the skin
  • Take photos in dim lighting
  • Cover the spot with makeup or cream
  • Leave hair over the area
  • Take blurry or out-of-focus shots
  • Photograph through clothing
  • Use heavy filters or editing

How to Photograph a Mole

Mole photography is essential for tracking changes and early melanoma detection.

  • Capture the entire mole plus 1-2cm of surrounding skin
  • Take photos from directly above, not at an angle
  • Include a ruler to track size changes over time
  • Photograph in the same lighting each time for comparison
  • Take photos monthly if monitoring for changes

How to Photograph a Rash

Rashes can spread and change quickly—capturing the full picture helps with diagnosis.

  • Capture the full extent of the rash, not just one spot
  • Take a wide shot showing distribution on the body
  • Photograph any blistering or texture from the side
  • Note if the rash has spread and photograph the edges

How to Photograph a Wound or Sore

For wounds, sores, or potential skin cancer spots, detail is critical.

  • Remove any dressings gently before photographing
  • Capture wound edges and surrounding tissue
  • Include depth perspective with an angled shot
  • Photograph any drainage or discoloration
  • Take photos before and after cleaning

How to Photograph Nails (Melanoma Under Nails)

Subungual melanoma can appear as dark lines or spots under fingernails or toenails.

  • Use macro mode on your camera if available
  • Press the nail gently against white paper for contrast
  • Photograph the entire nail from cuticle to tip
  • Capture any dark lines or spots under the nail
  • Include good lighting to see through the nail plate

How to Photograph the Scalp

Scalp lesions are often missed because they're hard to see and photograph.

  • Ask someone to help—it's difficult to photograph your own scalp
  • Part the hair to expose the area clearly
  • Use a comb or fingers to hold hair aside
  • Take multiple photos from different angles
  • Ensure bright, even lighting on the scalp

Note: Quality photos improve AI accuracy, but AI screening is not a substitute for professional medical evaluation. If you have concerns about a skin spot, consult a dermatologist.
