However, pictures taken using this setting have a lower contrast
range. When using this sensitivity setting, it is important to make sure
that important parts of the image are not overexposed.
As well as the fixed settings, the Leica M also features the
function, in which the camera automatically adjusts the sensitivity to
the ambient brightness. In conjunction with aperture priority mode
(see p. 182) this extends the range for automatic exposure control.
However, when using the function it is also possible to specify
priorities, for example for compositional reasons.
Note:
In large and evenly bright subject areas image noise as well as
horizontal and vertical stripes may become visible, especially when
using high ISO sensitivities and subsequently processing the image.
The function is not available with a manual exposure setting and when using flash
