Bracketing / 139
BRACkeTINg
Many attractive subjects are very rich in contrast, i.e.
they have both very light and very dark areas. The
effect can be quite different, depending on which
sections you base your exposure on. In such cases,
the bracketing function on the Leica M9 – in aperture
priority mode – allows you to produce several alter­
natives with graduated exposure, i.e. using different
shutter speeds. You can then select the most appro­
priate picture for further use, or use image processing
software to create a picture with an exceptionally high
contrast range (Hdr).
The following options are available:
– 4 graduations: 0.5eV, 1eV, 1,5eV and 2eV
– 3 numbers of pictures: 3, 5 or 7
– 2 sequences: Correct exposure, over exposure(s),
under exposure(s), or under exposure(s), correct
exposure, over exposure(s).
Notes:
• When using the bracketing function, all AUTO ISO
settings (see p. 128) are defined:
– The sensitivity automatically determined by the
camera for the first picture is also used for all
other pictures in a series, i.e. this ISo value is not
changed during a series.
– The settings in the
AUTO ISO
sub­menus are inef­
fective, i.e. the full shutter speed range available
on the camera can be used.
• Depending on the initial shutter speed, the working
range of the bracketing function may be limited.
Examples (in each case with defined aperture set ­
ting):
– Metered shutter speed
1
/
1000
s, bracketing series
of 5 pictures/2eV: limited function as the ­2eV
picture would require
1 /
16000
s.
– Metered shutter speed 1 /
125
s, bracketing series
of 5 pictures/2eV: unlimited function as the ­2eV
picture is possible with
1 /
2000
s.
– Metered shutter speed 1 /
1000
s, bracketing series
of 7 pictures/1eV: limited function as the ­3eV
picture would require
1 /
8000
s.
– Metered shutter speed
1
/
500
s, bracketing series of
7 pictures/1eV: unlimited function as the ­3eV
picture is possible with
1 /
4000
s.
• Regardless of this, the specified number of pictures
are always created, which means that several pic­
tures in a series may have the same exposure.
• For series of 7 pictures, only the 0. 5eV and 1eV
graduations are available.
• Bracketing is not available in flash mode. If an
attached flash unit is switched on, no pictures are
taken.
• The function remains active until it is switched
off in the menu. If it is not switched off, a further
bracketing series is produced each time you press
the shutter release button.
Setting the function
1. In the image parameters menu (see p. 103/119),
select Bracketing (4.2.5) and there
2. set whether you want to switch the function on
or off.
3. In the main menu (see p. 102/119), now select
Bracketing setup (4.1.9),
4. select No. of exposures , Sequence , and/or
EV increments
in the sub­menu, and then
5. the desired values and options in the respective
sub­menues.
