Do you use (or find you have any) 'down time' whilst out taking photos?
I'll define 'down time' as the time between when the light is not really any good for capturing good photos. that could be between breaks in the cloud, rain, say between 11 and 2PM or whatever.
eg. If you're out trying to capture some crepuscular rays, and the clouds are not playing the game for a little while, say half an hour or so, where it gets completely overcast and dull, but I can see that they'll produce their best once again very soon.. what would do you do?
Plan another scene, look around your current location for other interesting things to photograph, stand on the roof of your car scouting for other interesting location/subject matter(my car has lots of dents on the roof, and I really need a roof rack ).
generally I'll scout around for a new location or have a quick break, firing off a few frames via remote control from the comfort of my vehicle rolling a ciggy (whilst the camera is out in the gale force winds).
Even while it's not conducive to great photography you can still reframe a scene and shoot it as a test to see how it looks as a scene. You don;t necessarily need to keep those images, as they may only be test shots to see if the scene comes out as you expected. Zoom in, zoom out, change direction by a degree or so.. etc
I try to 'predict' the conditions about to unfold and try to place myself in a reasonable location to make best use of them, or a higher location to get a birdseye perspective or whatever, the point is to try maintaining a dynamic approach even though the time isn't perfect for capturing the image at that moment.
