Start with your clinic's instructions
Ask your clinic when it wants photographs taken and whether patches or markings should remain in place. Instructions can differ by test and clinic. Take photos only at the times your care team recommends.
Make each image easy to compare
Use even lighting and keep the camera steady. Include the whole test area in one overview photo, then take closer photos if your clinician has asked for them. Try to keep the angle and distance similar when you photograph the area again.
- Avoid beauty filters, color filters, and heavy editing.
- Keep the skin and any clinic markings in focus.
- Check the image before you leave the camera so you can retake a blurry shot.
Keep the context
Save the date and time with each image. If your clinic gave you a test map or patch record, keep it with the photos. A picture can show an area of skin, but the map and clinical history help a professional understand what was tested.
