You need to use a lot of water and rinse your plate thoroughly. I quickly dip mine in a tray of water and raise it up several times to stop the development. Then it either gets a rinse under the faucet for 30 seconds or it is transferred to another rinse tray and agitated as before for 30 seconds. The key to knowing when it has rinsed enough is to be sure the water runs off it as an even sheet rather than forming rivulets. It is exactly like checking the plate after it comes from the silver tank. If you see rivulets, it isn't ready for the next step. In terms of the rinse, I always give the plate even more water after I can't see rivulets.

Well, OK. They are reflections. But your post asks about ambrotypes. And, on the one plate the pattern off the plate looks like it continues beneath the plate. Again, use a black background when you take photos of your plates and watch out for reflections.

It kind of hit me today that it could be evaporating being that it is exposed to more air? I know the plates look bad they actually in some ways look better after i photographed with with my iPhone at least the contrast does. I think in part what your seeing might be my pouring both collodion and the developer. sometimes i am not getting enough collodion in the plate and have to add more so it looks uneven. also with the developer i added a new light my dark room was super dark so i could not see at all. It was fine for paper but for this it was just way to light.
I have left my silver nitrate solution in an enclosed, gasketed tank for nearly one year with no ill effects. Definitely clean your development tray. Most do it after every plate.
