Pushed to 25600, development time 7 minutes 30 seconds.
What you're seeing is mostly scanner noise, and I'm sorry but that can't be helped unless I do multipass, but the registration is so poor that it'll blur/move the image.
Anycase, not much in the image worth that.
This was an experiment to see how far it would go, the fact it came out this "well" is damn good I think.
May not have great density... but it sure has a whole lot of thinsity! :D
