The quality of X-ray picture depends on various operational factors starting from storage and loading of films upto the end product i.e., X-ray picture presented for reading. This article discusses some of the operational problems faced in maintaining the quality of the X-ray picture and how to overcome them. Factors that influence the quality are 1) Equipment with proper controls 2) developing time -6minutes developing time at 20o c is ideal for MMR. 3) good quality of developer 4) use of safe light which should be kept 1 meter away from tank 5) processing of film with standard timer with a margin of +1mt and 6) use of timer and thermometer (10o 30o). It is observed that in many institutions and hospitals accessories like dark room timer and thermometer are not available and films are developed by inspection method.

(i) By observing time and temperature control with the use of dark room timer which rings at a set time and a dark room thermometer, we are sure of the final quality of X-ray picture. (ii) Avoid the inspection method of viewing the film which carries active developer chemicals on the film during development. This method of development reduces the quality of X-ray picture. (iii) Regular use of dark room timer, dark room thermometer in the dark room ensures a good quality of X-ray picture and thus avoids retake which means cost, time, waste of man power and additional radiation exposure.
