Note
• The markings on the filter adjustment
ring serve merely as a guide.
• For more information on the points
that follow below, read and observe
your camera’s operating instructions.
• The effects described in this section
apply to photographs and videos.
5.1 Large aperture (small f-number)
Gives a shallow depth of field. This is how
you obtain an exposure effect on objects/
subjects in the foreground against a highly
blurred background, or vice versa with the
right focusing.
5.2 No aperture (large f-number)
Gives a large and extensive sharpness range.
Foreground and background are pictured
with equal sharpness.
5.3 Short exposure time
Gives a sharp picture of a fast-moving object
against a sharp background. For example,
flowing, splashing water is frozen in motion.
5.4 Long exposure time
Gives a blurred picture of a fast-moving
object against a sharp background.
Shots of moving water (stream, waterfall,
waves) are more dynamic. Water ‘flows’,
waves turn to ‘cotton wool’.
Guide value for the exposure time: 1/60
seconds or longer.
• However, if the camera is pulled in
synchrony with object movement, the
moving object will appear sharp against a
blurred background.
• With this type of image, the picture
stabiliser must be switched off (if your
camera has one).
