Have you ever finished a shoot thinking that your images are
perfectly sharp on your LCD screen, only to find that, once they are on
your monitor, they aren’t quite as sharp as you thought they were? Here
are a few tips to help you achieve sharper images.
1. Your Lens
We often read that opening your lens as wide as it will go is a best
practice because it lets the maximum amount of light into the camera,
and creates a blurred background. However, this is not always the case,
and you might want to try avoiding opening your lens as far as it will
go. If your lens will open to f/1.4, try stopping it down to f/2.8. If
you have your lens wide open, you run the risk of having only part of
your subject in focus (for example, their eyes will be in sharp focus,
but the rest of their face will be slightly blurry) or, if you are
shooting more than one person, the person your camera focuses on will be
sharp, while the other person (or the rest of the group) will not be
sharp. Adjusting the aperture just a couple of stops will still let
enough light into the camera and create a blurred background, but more
of your subject will be sharp.
2. Your Camera
If your camera moves too much while you are shooting, you will
slightly blur your subject. This is often referred to as camera shake.
If you are shooting without a tripod, make sure to gently press the
shutter. Even if you have steady hands, if you press the shutter too
vigorously, you can create a slight camera shake that will cause a blur
that is not visible until the images are viewed or printed large. If you
have unsteady hands like I do, you may want to try using a tripod. If I
am excited, happy or nervous, my hands ALWAYS shake, no matter what!
So, I use a tripod as much as I possibly can. Using a tripod may seem
impractical at first, but the more you use it, the more comfortable it
becomes. Personally, I prefer to take that extra step to make sure my
subject isn’t blurry!
3. Your Subject
Depending on your subject, you will need to adjust your shutter speed
accordingly. If you have a fast-moving subject, you’ll need a fast
shutter speed. However, if you are shooting portraits, or your subject
has very little movement, you can get away with a slower shutter speed.
Also related to shutter speed is the focal length of your lens. There
is a (very) general rule of thumb that associates focal length with
your minimum shutter speed to avoid camera shake. The equation: minimum
shutter speed = 1/Focal Length (in millimeters). So, if you have an 80mm
lens, your minimum shutter speed would be 1/80th of a second. Or, if
you have a 50mm lens, the minimum would be 1/50th of a second. This is
just a general rule of thumb, and the minimum shutter speed you can
achieve also depends greatly on the steadiness of your hand. Like I said
earlier, I have unsteady hands when I get excited (and I always get
excited when I’m shooting!) so I usually take my focal length and
multiply it by 4, and that is my minimum shutter speeds. So, if I am
shooting with a 50mm lens, 50 X 4 = 200, so 1/200th is my minimum
shutter speed to avoid camera shake.
4. Shooting in RAW
If you are shooting in RAW, once you import your images to Lightroom
or Camera Raw, your image will appear less sharp than it did on your LCD
screen. At this point, if you are using Lightroom, you will need to
tweak the Sharpness and/or Clarity in your post-processing. Don’t overdo
it, though! A little bit of sharpening goes a long way!
