To never open a thread that has rule of thirds in it's title. It is not okay to put everything in one third of a horizontal image and leave the rest totally blank... there is also something called balance. The rule of thirds is all about teaching balance, not using it as an excuse to call an out of balance picture okay. We are teaching a generation of photographers to make bad pictures and I don't give a rats behind who tells you different. Yes it's fine to do that, if you are going to put it in a magazine and lay words in the blank space. I is not okay to just shoot it as if it is high art.... Okay markc maybe that is just my opinion since i didnt bother to google it but I'm not alone in it.
