Two bath development technique

I've been having problems with using two bath development with regards to uneven development. If any one can help I'd much appreciate it.So far I've had these reasons, agitation, quality of water,careful draning of the f irst bath, I've concentrated on all of these but still have uneven development.

Just a couple of questions. What size film are you using? What type of development are you doing, tank, rotary, trays, hangers? Exactly what process are you using, DD-23, DD-76? And what are your times for bath A and B?

Thanks, these answers might help in determining your exact problem.

Are you asking about development of negatives or prints?
