Processes at the initial stages of the formation of latent image centers in silver halogen emulsions by the action of ionizing photon radiation are considered and analyzed. An algorithm for their formation is presented. Imbalance of two competing processes — exposure and processing — causes artifacts. Based on expert assessment radiographic images with artifacts were investigated. Various types of artifacts are described, reasons from origin are indicated, album of photos with artifacts is compiled. Recommendations are formulated to prevent the occurrence of artifacts while manual method of manual film processing. Keywords: X-ray film, imaging, algorithm, latent image, exposure, processing, artifact, album.
