    Of the methods I looked at, for B&W negative sheet films I found, to my surprise, classic hand shuffling in open trays to be one of the better methods when it comes to development uniformity. It was...

    It seems there is a current version. Very expensive, although I suppose you have to kind of think of it as buying three lenses, sort of. I’ve never used one so I have no idea how well or not well...

    Ah - didn’t know that. Well that isn’t very good. How about a halogen lamp? Quartz halogen is common in enlargers.

    Re: What went wrong? cloudy negatives

    It must be something like this (or maybe something went wrong in-camera?).

    OP said one of the four sheets came out fine. That means it cannot have been a problem with the chemicals.
