Popis: Digital cameras offer the possibility to capture and analyze data in a simple and affordable way, allowing quick and in some cases on-site shots of the study object. This research use a DSLR (Digital Single Lens Reflex for its acronym in English) and a CCD (Charged coupled device for its acronym in English) to capture digital images analyzed under two methodologies using a MATLAB script, water samples Obtained from two areas of Antioquia Colombia, and three water bodies: rio San Carlos and brook San Antonio in San Carlos (Ant), in addition to brook La Marinilla in Marinilla (Ant). In addition to the foregoing, two capture environments were built to capture digital images and two trials in order to establish a correlation equation between the data obtained in light intensity and turbidity (NTU). Finding that there is a correlation between turbidity and the intensity of light extracted from digital images with R ² = 0.97428 for the first trial, and above 0.9 for the G-channel in the RGB color space.
