What are these spots all over my pictures?

Being that it's a film camera it takes dust on your sensor out of the question. If this is an SLR and you've been swapping out lenses maybe you got something on the rear of the lens. If that were the case the drops would be in the same locations from print to print. But the spots look to big for that explanation. More likely their processor had a bad day. Run off another roll and try again. I know that's not cost effective. Before you load the film check the seals and film bay for anything suspicious.

This looks optical rather than a processing fault. I suspect a faulty shutter in the camera. Was it left pointing at the sky between shots?

I think I figured it out. I accidentally opened the camera with the film inside. I didn't think much about it at the time cuz I thought that it would only affect a couple of shots but apparently it got most of the roll. Thx for all the help
