Best Practices for Digital Color Photography in Medicine
Collect industry best practices in the field of digital photography and write a guidance document which can be used by the medical industry to minimize the color errors created during the digital color camera image capture process.
This guidance document will apply for a range of digital cameras (from cellphone cameras to scientific grade cameras) and lighting conditions. Recommendations will also be made for camera setup and color correction in post processing.

Images on the left below are uncalibrated, calibrated images are on the right.
Image 2. Ulcer. Similar problem as for Image 1: white-balance produced a green tinge. Courtesy of Dr. Sven Van Poucke, Ziekenhuis Oost-Limburg, Belgium.
Image 3. Animal experiment, using a very simple color chart. Courtesy of Dr. Sven Van Poucke, Ziekenhuis Oost-Limburg, Belgium.
Images 4 and 5. Vitiligo. Original images (left) were taken only seconds apart using full automatic settings of the camera, producing very different images. Courtesy of the University Hospital Ghent, Belgium.
Image 6. Pigmented lesion. Over-exposed image, masking a lot of specular reflection. Calibration recovers this partly. Courtesy of the University Hospital Ghent, Belgium.
Image 7. Ulcer. Camera was in full automatic mode, but the original image is still very yellowish partly due to typical hospital wall colors. Courtesy of the University Hospital Ghent, Belgium.
