When I first got it, I had no problems. Now that I have used it a while, I get issues. White dots on the negatives, swirl marks on the film along 1 edge (always the edges with sky in them, even from film in same holder which would reverse sky positions from one another when developing. Happens whether or not there is pre-soak, etc. Not to mention other weird stuff with under development in corners and such (not lens issue as it happens with any of my lenses and regardless of film holders as well.) Perhaps I need to just use trays or buy a better daylight tank. I know some have no issues, but how hard can this be? It isn't rocket science.

Mix developer, stop bath, fixer, hypoclear to proper dilutions, stabilize at correct temp 68 degrees, then pour, develop, etc. I agitate properly or so I think I am, I do an initial agitation (not hard), the rotate every thirty seconds or as prescribed by developer, pour out, put in stop bath, same thing, fixer, etc.

I wonder if it is because I hold the tank at a slight angle as I pour the chemicals in if that would do it? I wouldn't think so, but never know. Weird that it is always around the edges of every piece of film I develop that has that problem Here is an example from latest. Tmax developer. This is one of the worst ones, but it looks like it was the edges got all jacked up on both long edges, so it definitely is something I am doing wrong with the SP445. Used fresh developer as well. Again, it isn't the holders as it will do this with new holders and old holders. I have gotten great negatives from the SP445, but lately getting crap. Any thoughts? Feel free to down the tif file and process the way you normally do if you are so inclined. It is a raw tif that I applied at gamma 2.2 to and saved as 10x8 at 300dpi. Notch is on upper right of film. Tmax100, f22, 90mm Schneider f/5.6 Super Angulon at 2 seconds. Not filters.

Help appreciated, not snide/rude or otherwise non-helpful comments not needed. I am trying to learn what is causing this and not do it in the future and hopefully this will help others.
