There are a number of differences between Phenidone/Hydroquinone (PQ) and Metol/ Hydroquinone (MQ) print developers, but none of them are significant enough to cause one to be preferred to the other. Perhaps the most important difference is the longer and more consistent working life of a PQ developer. This is because Phenidone is less sensitive to bromide so the build-up of bromide in solution has little effect on its activity. However, it should be noted that the organic restrainers found in high pH PQ developers are carried off by the print. While this will not affect the activity of the developer it will have some affect on the overall contrast of succeeding prints.
