There are two lessons we rapidly learn about photographing any subject (not just close-ups) where the shot you have in mind can be lost due to changes in circumstances (change in weather or just the lighting; movement away/reorientation of the subject; movement of more subject matter to obscure that which you desire to frame):homestar455 wrote:Come to think of it, I did try a few of that grasshopper in portrait orientation... But he flew away before I could align the camera in a way I liked...
1) Quickly, but carefully, get a shot which, at least approximates (angle of view, format, composition and lighting) to what you intended. The exception is that it may be wise, with live animals, to err on the side of keeping a little more distant (with the bonus of greater DOF) than you would prefer. Then try variations, including closer approach, if there is still opportunity.
2) Be prepared for unexpected different, possibly better, shots which you did not anticipate.
