Quizplus · Accepted Answer

mAs reciprocity has an acceptance parameter of ±10%. This means that when the mAs is changed, the resulting image should have the same density or brightness as before the change, within a range of ±10%. This ensures that the exposure factors are consistent and that the image quality is maintained. A tighter acceptance parameter (such as ±5%) might be too restrictive, leading to frequent retakes, while a looser parameter (such as ±20%) might allow for too much variability in the image quality. Therefore, ±10% is the best choice for a practical and effective mAs reciprocity parameter.
