3. What is a simple method of determining the center exposure, number of brack-
ets, and the exposure value separation?
Use an evaluative metering mode to determine the center 'Time/Exposure' setting and
then simply choose three brackets with a larger EV separation such as 1.7 EV or 2.0
EV.
4. What is an accurate method of determining the number of brackets and the
exposure value separation?
Determine the exposure for the brightest, average, and darkest areas that you would
like to be able to see details. Use the following steps:
• Change the metering mode to spot mode, if your camera has that capability.
• Point the camera lens to each area and depress the shutter button half way to
determine the shutter speed that will center the reflective meter marker to zero.
Take note of the shutter speeds as you do this.
• Determine the distance from the average exposure which you use to set 'Time/
Exposure'. Do this by counting how many shutter speeds settings your darkest
and brightest shutter speeds are away from your 'Time/Exposure' setting.
• The default setting for shutter speeds in DSLR cameras is 1/3 stop. When you
change the shutter speed three times you have changed the exposure by one
exposure value or one EV.
Set the metering mode on your camera to spot meter
Please refer to your camera's user manual for specific information. See table below for
instructions on setting the metering mode for each of the following cameras.
Canon 5D Mark II
Small WB button
on the top right
hand side of the
camera. Use the
small dial on top
of the camera to
select spot meter.
*The cameras use the quotation mark similar to the way the North American decimal point
is used. In Europe, the comma is used to denote the decimal point. DSLR viewfinders will
display only the denominator if the shutter speed is a fraction while the LCD will display the
entire fraction.
Canon Rebel T1i
Press the set but-
ton in the middle
of the directional
buttons on the
back right hand
side of the camera.
Use the buttons
that surround to
navigate to the
icon that is on the
right hand side
and the third row
up. Press the set
button again. Use
the left and right
buttons to select
spot metering.
Nikon D700
There is a dial that
is to the right of the
eye piece. Rotate
the dial counter
clockwise until it
points at the single
dot. This sets the
metering type to a
spot meter.
Nikon D90
Use the Center-
Weighted Area
metering mode.
The default circle
is 8mm. You can
change this to
6mm for a smaller
spot.
This is changed in
Custom settings B
menu underneath
b3 center weighted
area. There are
other metering
settings that can
affect metering.
