Several years ago I was photographing in Yellowstone National Park rather early in the morning as I recall it was looking East down the Nez Perce Creek. Everything about the lighting with mist and all was perfect. Just after removing my camera from the tripod and placing it back in my backpack from behind my view a flock of ducks or geese in perfect "V" formation flew into the scene in just the right position of what would have been the frame. Oh well, that's how it goes at least the picture remains in my mind's eye (the location of my best pictures that got away).
What gets me are the times when I *get* that instant of light, everything goes off perfectly, I'm sure I've taken the Greatest Photo Ever, and then when I develop it, the image that I imagined so brilliantly turns out to be completely blah.
The speed of dark is known to be greater than that of light. It must be, otherwise the dark wouldn’t be able to get out of the light’s way.
Except in this case,, darkness does not want to get off the way, but go where it wants ;-)
All of the above and probably some others I've chosen to forget, too. Murphy and me, we go waaaaaaay back. ;-)
