Abstract

Background/purpose: Although digital cameras have powerful macrocapabilities, flash macrophotographs are often unsatisfactory. The aim of this study was to develop a light-emitting diode (LED) illuminator for macro digital photography that allows colorimetric investigations of the skin. Methods: We devised an LED illuminator suitable for acquiring super-macro digital images of the skin. Reference CIELAB color chart values were compared statistically with computed values from digital images in order to obtain equations for real CIELAB values. Using these, we acquired and analyzed images of various dermatological conditions using an LED illuminator. Results: The images obtained with the devised LED illuminator were more reproducible than flash-assisted photographs. With proper camera settings, the devised LED illuminator and the color analysis method developed during this study provided digital skin images containing colorimetric information. Conclusion: A digital camera equipped with an LED illuminator is a useful tool for dermatological research and clinical practice.
