If you're shooting flowers outdoors, you're bound to run into the natural enemy of flower photographywind. There's nothing more frustrating than standing there, tripod set, camera aimed and focused, and you're waiting for the wind to die down enough to get the shot. This is especially bad if you're shooting macro, where the slightest movement spells disaster (well, not disaster, but a really blurry photo). You can try the old use-your-body-to-block-the-wind trick (which rarely works by the way), but you're actually better off letting the camera fix the problem. Switch to shutter priority mode (where you control the shutter speed and your camera takes care of adjusting the rest to give you a proper exposure), then increase the shutter speed to at least 1/250 of a second or higher. This will generally freeze the motion caused by wind (unless it's hurricane season). If the higher shutter speed doesn't do the trick, then you have to go to Plan B, which is making the wind the subject. That's right, if you can't beat 'em, join 'emuse a very slow shutter speed so you see the movement of the flowers (you'll actually see trails as the flower moves while your shutter is open), and in effect you'll "see" the wind, creating an entirely different look. Give this seeing-the-wind trick a try, and you might be surprised how many times you'll be hoping the wind picks up after you've got your regular close-ups already done.
