Ten lesions were photographed with an entry-level (HUAWEI P smart 2019), a midrange (Samsung Galaxy S8) and a high range (Apple Iphone XR) smartphone camera and with a digital single-lens camera (DSLC). Images were independently rated by 3 pathologists, based on comparison to the real lesion and "visual impact." Difference of perceptual lightness coordinates between smartphones and the criterion standard (DSLC) was calculated.The highest ranking for adherence to reality was obtained with DSLC, while the highest ranking for visual impact was obtained with the Iphone. The color representation better reflecting the criterion standard (DSLC) was obtained for the entry-level smartphone.All the devices allow to assess the general features (ie, the color, the shape, and the main characteristics) of an injury during a forensic autopsy. However, results might be different when photos are obtained in suboptimal, such as low-light, conditions. Moreover, images acquired through a smartphone camera might be unsuitable for later image exploitation, such as enlargement of a portion of the image to magnification of a detail, which seemed not relevant when the photo was shot. Only a raw image, acquired using a dedicated camera and deactivating images manipulation software, might allow the preservation of the true data.
用入门级（华为 P smart 2019）、中端（三星 Galaxy S8）和高端（苹果 iPhone XR）智能手机相机以及数码单镜头相机（DSLC）拍摄了 10 个病变部位的照片。3 名病理学家根据与真实病变的比较和“视觉冲击”对图像进行独立评分。计算了智能手机与标准（DSLC）之间感知亮度坐标的差异。DSLC 的现实性评价最高，而 iPhone 的视觉冲击评价最高。入门级智能手机的颜色表现最能反映标准（DSLC）。所有设备都可以在法医解剖期间评估损伤的一般特征（即颜色、形状和主要特征）。然而，在光照条件不佳等情况下拍摄照片时，结果可能会有所不同。此外，通过智能手机相机获取的图像可能不适合以后的图像开发，例如放大图像的一部分以放大细节，而在拍摄照片时这似乎并不重要。只有使用专用相机拍摄并禁用图像处理软件获取的原始图像才能保留真实数据。
