Here we will break down all three and think about possible considerations to increase image sharpness.
in the frame, either from a moving subject, or from the camera being less than completely still at the time the shutter is open, will cause motion blur in your image. Depending on the type of gear you are using or have available, there are ways to reduce and/or eliminate this movement.
2. Shutter Speed
Shutter speed (a bit of a misnomer) is the duration of time that the shutter is open. The shorter the amount of time that the shutter is open, the less movement can happen during the capture of the image. The downside of a fast shutter speed is that less light makes it to the film or sensor, making it necessary to shoot at a higher ISO or at a wider aperture. Therefore, the maximum shutter speed for any given situation varies but, in general, you’ll want to shoot the fastest shutter speed possible to maximize sharpness.
3. Stance / Brace
Even the Queen’s sentries at Westminster Abby move. No one can stand completely still. Using proper photographic technique will help reduce camera movement when taking the photo. Also, if possible, bracing yourself against a wall or other solid structure will help steady your body while shooting.
