Some of the banding that I'VE had has been caused by me. Sometimes when the tray development process is extremely long and I'm bored or distracted, I've inadvertently let the paper rise to the top of the developer for too long and that causes uneven development. It can appear as almost-parallel bands; usually around the centre of the image, tho' that depends on how the particular paper curls. If I must leave a paper for 30 seconds or so, I've taken to carefully weighting it with something in order to keep it immersed. |
