I've been having issues with negatives turning up slightly more developed on one side as if their is a line sort of in the middle. I've just started using BTZS tubes with 4x5 film. I use Clayton F76 and follow the directions of filling all of them and then shaking for 15s then rolling the rest of the development time. I wonder if maybe I'm not getting some of them shaken enough or if the first one I fill is sitting too long before I get to shaking all of them.

Any thoughts?

These "scans" are just quick pics with my digital Ricoh on a light table but if you look at the middle you should get an idea.(the left side is a glare from another lamp I had on in the room)
