    Introduction: With the ever-increasing number in adults seeking dental treatment, improvement in esthetics has remained one of the main goals in the treatment objectives. The emphasis has long been on taking study models and radiographs as records, while photographs were often considered as luxury and time consuming. With time, this idea has certainly changed, and photographs were considered important diagnostic records. The aim of the study is to compare the image quality of intraoral photographs taken using the macro lens and normal lens of a particular digital single lens reflex camera. Materials and Methods: This study includes a questionnaire with 20 image based on multiple choice questions and was distributed among dental undergraduates and postgraduates in the city. The digitized photographs in the questionnaire were assessed based on the quality of photograph, depth of field, reproducibility, brightness, and contrast. The data obtained were then subjected for statistical evaluation. Results: Nearly 64.11% of the total response suggested that both the pictures were taken in a macro lens and a normal lens are similar whereas 24.15% and 11.74% opted for macro lens and normal lens, respectively. Conclusion: Macro lens performs better than normal lens. However, a majority of the study population found no difference between the two photographs taken using normal and macro lens. Macro lens was found to produce more pleasing images in frontal occlusal photographs.
