Test roll with a new olympus 35 sp

Hi guys , at the bottom of every frame there are these markings. The same happened when I shot a test roll with my yeshica electro. any ideas? Im developing these myself. thanks in advance.

These are classic sprocket hole streamers they are surge marks caused by to much developing tank agitation during development.

awesome ben. so both cameras are working as they should. thanks again.

Can you describe your developing process and materials? Yes, they're surge marks.

I've seen those before :]

My guess is that you're using the little stick to twirl your film reel in the developing tank. That's how I got them years ago. After throwing that sucker as far as I could, I went to GENTLY inverting my tank using a slow, swirley, twisty sort of motion (easy does it on this too) and they have never reappeared.

If you're not using said stick and are inverting your tank already, just calm down on the agitations, use the slow, swirley, twisty motion, and there you go. Make sure you're filling the tank w/ the proper amount to fully cover the reels too, fixing enough, and don't use short developing times.
