Get set up
The shutter speed will vary depending on the light
conditions, so a tripod is essential for capturing
pin-sharp shots. Screw the adaptor ring on to your lens and
slot the filter holder on to it. For full control over the
exposure set your D-SLR to manual mode, and enable Live
View mode to help compose the shot, and also so that you
can see the effect of the filter clearly.1
When to use an ND grad
ND grads are generally used to hold back the brightness
of the sky so that you can capture a balanced exposure
when shooting high-contrast scenes; they’re a great addition
to your kit bag because you can use them in a range of
situations. We took a walk along the Kennet and Avon canal
in Bath to capture some scenic shots on a sunny day.3
Compose and focus
Compose your shot using the rule of thirds, keeping
plenty of sky in the frame. You’ll need to focus before
fitting the filter, so zoom in using the 10x magnification view,
switch your lens to manual and focus manually. Be careful not
to knock the focus ring when you’re attaching the filter.5
Filter density
Now meter from a midtone in the sky – the difference
in exposure between the sky and foreground readings
determines the strength of filter required. For example, if the
suggested reading is 1/60 sec at f/16 for the foreground, and
1/250 sec at f/16 for the sky, that’s a difference of two stops,
so a two-stop ND grad should be just right.4
Camera settings
Before you attach the filter you need to know your
exposure settings. Set a narrow aperture of f/16 for a
broad depth of field, and a low ISO for maximum quality.
To determine what shutter speed you require, meter from
a midtone in the foreground; the filter will prevent the sky
from being over-exposed with the resulting shutter speed.6
Fit the filter
If you’re using slot-in filters, slot your required filter
into the holder. There will be more than one slot, so
start with the one nearest to the lens; the other slots enable
you to stack filters. You can twist the holder to align the filter
with the horizon, and use Live View to help you position the
filter so that the gradient is on the desired area.
