Objective:The aim of this paper is to document the practice of photography among clinicians whose daily work depends and is influenced so much by medical photography.Materials and Methods:Questionnaires documenting the bio data, place of practice, and experience of cleft caregivers with clinical photography were distributed. Knowledge of rules guiding clinical photography and adherence to them were also asked. Types of camera used were documented and knowledge of the value of clinical photographs were also inquired.Results:Plastic surgeons constitute the highest proportion of 27 (38.6%), followed by Oral and Maxillofacial surgeons with 14 (20.0%). Twenty one (30.0%) of the respondents always, 21 (30.0%) often, 12 (17.1%) frequently, while 9 respondents sometimes took photographs of their patients. Suggested uses of clinical photographs included training, 52 (74.3%), education, 51 (72.9%), medicolegal, 44 (62.9%) and advertisement, 44 (62.9%) among others. Twenty two (31.4%) did not know that there were standard guidelines for taking clinical photographs. Twenty three (32.9%) of them did not seek the consent of the patients before taking clinical photographs.Conclusion:While the practice of clinical photography is high among African cleft caregivers, there is a need for further education on the issues of standard rules and obtaining consent from patients.

The smartphone is one of the biggest revolutions in the era of information technology. Its built in camera offers several advantages. Dermatologists, who handle a specialty that is inherently visual, are most benefited by this handy technology. Here in this article, we attempt to provide an overview of smartphone photography in clinical dermatology in order to help the dermatologist to get the best out of the available camera for clinical imaging and storage

“…Therefore, reproducibility is poor. This may be less important when photographs are taken for documentation purposes, but when digital photography becomes part of medical evaluation or is used to perform measurements, it becomes critically important [5,6,18,23-29]. In our view, the quality of medical photography is principally defined by its reproducibility and accuracy [21].…”

BackgroundRecently, digital photography in medicine is considered an acceptable tool in many clinical domains, e.g. wound care. Although ever higher resolutions are available, reproducibility is still poor and visual comparison of images remains difficult. This is even more the case for measurements performed on such images (colour, area, etc.). This problem is often neglected and images are freely compared and exchanged without further thought.MethodsThe first experiment checked whether camera settings or lighting conditions could negatively affect the quality of colorimetric calibration. Digital images plus a calibration chart were exposed to a variety of conditions. Precision and accuracy of colours after calibration were quantitatively assessed with a probability distribution for perceptual colour differences (dE_ab). The second experiment was designed to assess the impact of the automatic calibration procedure (i.e. chart detection) on real-world measurements. 40 Different images of real wounds were acquired and a region of interest was selected in each image. 3 Rotated versions of each image were automatically calibrated and colour differences were calculated.Results1st Experiment: Colour differences between the measurements and real spectrophotometric measurements reveal median dE_ab values respectively 6.40 for the proper patches of calibrated normal images and 17.75 for uncalibrated images demonstrating an important improvement in accuracy after calibration. The reproducibility, visualized by the probability distribution of the dE_ab errors between 2 measurements of the patches of the images has a median of 3.43 dE* for all calibrated images, 23.26 dE_ab for all uncalibrated images. If we restrict ourselves to the proper patches of normal calibrated images the median is only 2.58 dE_ab! Wilcoxon sum-rank testing (p < 0.05) between uncalibrated normal images and calibrated normal images with proper squares were equal to 0 demonstrating a highly significant improvement of reproducibility. In the second experiment, the reproducibility of the chart detection during automatic calibration is presented using a probability distribution of dE_ab errors between 2 measurements of the same ROI.ConclusionThe investigators proposed an automatic colour calibration algorithm that ensures reproducible colour content of digital images. Evidence was provided that images taken with commercially available digital cameras can be calibrated independently of any camera settings and illumination features.
