I’m not aware of any specific examples, no, but as a photographer I would say a guide should have more info in it about what exactly you might look for when composition using negative space is important. Things like bad examples vs good examples, and if you have a good shot, but are considering using Lightroom to help yourself out of an overcast day etc. since I’m being asked, give me a bit of time and I’ll find something a bit more in line with what I’m thinking about.
