Methods Based on Digital Image: from General Considerations to Chemistry Teaching

This work is a bibliographic review of the Digital Image Based (DIB) from fundamental research to chemistry teaching, with an emphasis on analytical chemistry regarding qualitative and quantitative approaches and for chemistry teaching. Therefore, an exploratory and descriptive study on the state-of-art was carried out. The principles to obtain a digital image, electronic devices used, chambers, sample platform, precision, accuracy, color models, data treatment, and apps available are discussed. The applications of digital images to medical, geology, physics, pharmaceutical, biochemical, food science, forensic science, environmental, teaching and other applications are discussed. Moreover, chemistry teaching is enriched when digital images are employed, which can increase the motivation and enthusiasm of students, making classes more attractive and ensuring better learning. Since there is a growing number of publications in the field of "digital imaging", it is essential to state that it is an area with enormous potential and much to offer for research and teaching.
