gamma). From this point, drop straight down to the time of development line and read 7.5. It takes 7 1/2 minutes of developing time at the recommended agitation. such as cleanliness, accuracy, and proper preparation Contamination can ruin a developer which, in turn, could ruin your images. Things, such as dirt and dust, in the solution can cause artifacts on the film. Use a good-quality medium-strength detergent to wash glassware and other vessels. Be sure that all washed entire area clean to prevent contamination and ensure changes that have taken place over many years. These improvements are made to keep pace with improved sensitized materials, processing equipment, and environmental regulations. The preparation and use of photographic solutions must be a systematic procedure based on accurate measurement and standardized methods. High-quality standards can be achieved only when the conditions of exposure, chemistry, and processing are all within operating tolerances. Then results are predictable. use. This helps us to keep chemicals up to standard. Analysis of the components of processing solutions is adjusting their composition for future use. These procedures are used to determine proper replenishment rates to promote the efficient use of chemicals. Quality assurance procedures are implemented, so solutions are mixed, used, and discarded properly. desirable, predictable, and consistent results. Chemical analysis procedures used to indicate chemical activity are valuable only when the samples analyzed are representative of the processing solutions. The analysis of a sample taken improperly may do more harm than good in controlling the process. precipitate. Even a clear solution may have different concentration levels in various parts of a processing tank; for instance, the chemical composition at the other parts of the tank. To compensate for this, you must use a prescribed procedure, so all the samples are taken from the same location, such as from a point near the tank overflow. These samples should be representative of the solution at an established Advanced Photography Course |
