subject such as in Spot-Hi or Spot-Shadow metering modes. In a
case where there are no spikes at either end of the histogram,
and the graph starts and ends near the edges, you have used the
entire tonal range available to you and your metering was correct
for the general tone of the entire scene.
If you press the INFO button once again the image will display
blocks of white where there is no detail present. If the areas
highlighted in this manner are not "mission critical" (i.e. you do
not mind that they have no detail in them) then you need not
worry any further.
If, however, your main motif has a great white block flashing all
over it then you will know that you have badly over-exposed the
image and need to try again. The solutions to the problem of
over-exposure are:
• Use the spot meter and measure off the main subject
using the AEL function.
• Take the subject again as before but press the +/-
button and turn the rear input dial to set -1.0, -2.0 etc.
• Use the bracketing function.
• Reduce the ISO setting in cases of gross over-exposure.
If you press the INFO button after viewing the highlight areas,
the blocks flashing (if there are any) will indicate the areas of the
scene where there are solid blocks of black without detail. As
before, you can steer around the problem by using the three
options described above but in this case – if using the +/-
compensation setting, you need to turn the dial to set a +1.0,
+2.0 or similar setting that increases the exposure bias.
POWER USER TIP: It is possible to use the custom functions settings
menu to allocate the +/- compensation function to either the main
(rear) or sub (front) input dial. This removes the need to first press the
+/- button before turning the dial to adjust compensation making the
use of this function faster and more immediate. Different functions can
