Photographs are an essential tool for the documentation and sharing of findings in dermatologic surgery, and various camera types are available.
To evaluate the currently available camera types in view of the special functional needs of procedural dermatologists.
Mobile phone, point and shoot, digital single-lens reflex (DSLR), digital medium format, and 3-dimensional cameras were compared in terms of their usefulness for dermatologic surgeons. For each camera type, the image quality, as well as the other practical benefits and limitations, were evaluated with reference to a set of ideal camera characteristics. Based on these assessments, recommendations were made regarding the specific clinical circumstances in which each camera type would likely be most useful.
Mobile photography may be adequate when ease of use, availability, and accessibility are prioritized. Point and shoot cameras and DSLR cameras provide sufficient resolution for a range of clinical circumstances, while providing the added benefit of portability. Digital medium format cameras offer the highest image quality, with accurate color rendition and greater color depth. Three-dimensional imaging may be optimal for the definition of skin contour.
The selection of an optimal camera depends on the context in which it will be used.
照片是皮肤科手术中记录和分享检查结果的重要工具，且有多种类型的相机可供使用。
鉴于皮肤科手术医生的特殊功能需求，评估当前可用的相机类型。
对手机相机、傻瓜相机、数码单反相机（DSLR）、数码中画幅相机和三维相机在皮肤科手术中的实用性进行比较。针对每种相机类型，参照一组理想的相机特性，评估其图像质量以及其他实际优点和局限性。基于这些评估，针对每种相机类型可能最有用的具体临床情况给出了建议。
若优先考虑易用性、可用性和可及性，手机摄影可能就足够了。傻瓜相机和数码单反相机在一系列临床情况下能提供足够的分辨率，同时还具备便携的额外优势。数码中画幅相机提供最高的图像质量，色彩还原准确且色彩深度更大。三维成像对于皮肤轮廓的界定可能最为理想。
最佳相机的选择取决于其使用场景。
