The appearance of a digital image is very important for a correct interpretation and, consequently, for a effective diagnosis. Purpose: There are many factors that may influence the quality of a digital image. The process of digitalization must be analyzed to make sure that possible negative interferences will be eliminated. Methods: Some of these interferences include image spatial resolution and image capture mode. Their repercussion in the dynamic range of digital images was analyzed by the program Photoshop (Adobe Systems Incorporated, Mountain View, California, USA). Results: The results showed that for a digitalized image, a spatial resolution much superior it is not required. Conclusion: For the digital images, the signal/noise ratio (SNR) cannot be neglected.
