I've been deving some bw film at home, but on one of my negatives there are a lot of little white spots everywhere.

Why has this happened, how can I prevent it from happening again, and how can I fix it?

My scanner does not have a clean option, so it's probably fix one by one in photoshop.

Thank you! Any advice is much appreciated.

    Looks like dust. How clean is your dev environment from the change bag through to the drying rack? Specifically with drying, is it done in a clean place with no airflow or only cleaned airflow? – Hueco Aug 19 '18 at 18:57

  • Windows are always drafty. If you have no dedicated place, then try using a seldom used closet and, once hung up, make sure not to open the door for ~a day. Make sure any AC/Heating vents in the room are also closed. No airflow is better than non-filtered air. – Hueco Aug 20 '18 at 21:12

It's been many years since I've done film developing, but I remember two likely culprits:

  1. Air bubbles from improper agitation. Generally these are very roundish.

  2. Minerals from hard water. These tend to be angular shapes.

  • could be improper agitation or drying, as I believe the water in my area is soft – plyck Aug 20 '18 at 19:45

Since you note:

they dry next to a window which could have been left open for this set of negatives

As Hueco explains (1, 2):

Windows are always drafty. If you have no dedicated place, then try using a seldom used closet and, once hung up, make sure not to open the door for ~a day. Make sure any AC/Heating vents in the room are also closed. No airflow is better than non-filtered air.
