Two directors that I've worked with stand out in particular. One was actually a pretty bad director when I first started working with her, but I kept working with her because she had a lot of vision. She just wasn't good at conveying what that vision was, both to me and to the actors, making it rather challenging to get what she wanted from the shoot. However, she's also one of those people who cares about as well as respects the people she works with, and has learned a lot; while she hasn't learned much about how to light a set, she's gotten a LOT better at explaining what she is trying to accomplish with a shoot, and her couple of films have been great to work on. The last one is still in post, the previous one was quite well received locally (got a jury nomination for "best short" for one local film festival). She takes a lot of inspiration from classic filmmakers.
Another has worked with me on probably something like a dozen projects now, though only a few as director. He directed the first feature film that I shot, and that was our first big collaboration. He goes his best to take care of his cast and crew as far as keeping our working days reasonable, saving the really long days for when we really need them (like when we have a particular location for only one day). He's also seasoned enough that when we're short on crew, he can jump in and assist with lighting and that sort of thing, which nearly backfired once when he was doing sound while I was operating the camera handheld with a shoulder rig, and I was using the battery as a counterbalance. He was looking over my shoulder to see the viewfinder, not accounting for how far the battery extended behind me when I did the whip pan... and accidentally gave him a good wallop on the jaw... on the take we ended up keeping. It turns out that since I didn't pause, you couldn't see the bump in the final footage.
Anyway, he and I quickly established a working relationship where I was able to get a solid sense of the style of what he wanted. We ended up using footage shot during rehearsals as our reference, like they were storyboards. He always had a very clear idea about what he needed in order to get the piece we were working on to fit into the edit, and I had no trouble figuring out how to light it. He's working on raising funds to pay for some pickups; hopefully we'll be able to get it into the festival circuit this year.
