Although there is one fundamental tip in this video, it's underlined by another tip that I'd like to focus on: revisit locations. It doesn't matter which genre you work in, revisiting a location for another shoot can be highly valuable. With portraiture, I like to do test shoots on locations and then return to them for the main event, as I do with weddings. With landscapes, as Denney discusses, it can be useful to return to the same location with fresh eyes, but also in a different season. However, I even find this advice useful with more obscure genres like macro. By learning an area and figuring out where the insects congregate, which parts are teeming with life and which are quiet, and which places are worth waiting in and which arent, I can come home with far more shots.
In all honesty, I am struggling to think of a type of photography where you wouldn't benefit from having a lay of the land already. Even when it comes to sport, I have had more success on my second and third times shooting a motorsport event than on the first because I have learned interesting angles, where to get the best panning shots, and so on.
So, get your boots on and go back to your old haunts!
