using the camera controls.
You can also configure it from your PC using the Canon software.

Exposure
Getting the exposure right can have a significant effect on how easy it is to
classify an image in HemiView, and on the accuracy results.
Aim to have areas of sky at the top end of the brightness range, and areas
of canopy at the lower end. Check this on your image by looking at the
brightness histograms.
On the Camera, select
to play back the image onto the LCD monitor
and toggle the
INFO
button to display image information, including a
histogram. (It may be easier to inspect histograms on your PC using the
Canon EOS software)
