there are 3 key things to getting sharp at really slow shutter speeds: stance, elbows, finger, and breathing.
- get in a boxing stance. if you've ever learned how to properly shoot a gun before, use that stance. shooting a camera is the same way, except maybe stand slightly more upright to get your center of gravity under the camera instead of expecting recoil.
- elbows: keep them tucked in and under the camera. an elbow flapping outside your body will not be stable. an elbow squeezed against your side will be.
- finger: don't stab at the shutter. stabbing at the shutter is probably the #1 source of vibration in your photos. instead, set your finger down on the edge of the shutter, then roll it onto the shutter to half-press, then roll it all the way on to take the shot.
- breathing: shoot after exhaling. if done right, you can see the wiggles go way down after you settle after exhaling halfway or two-thirds, then holding your breath.
so, here's the order in which I take a shot at slow shutter speed:
- get in a boxing stance
- lift camera, tuck elbows
- inhale, hold breath
- frame and focus using finger roll technique
- exhale two thirds, hold breath
- gently and smoothly squeeze the shutter
- remember to hold the camera steady until I can see the target again
