(still
photography)
Choose a value for ISO sensitivity. ISO 200 offers a good balance between
noise and dynamic range. Choose [L100] or [L80] for larger apertures (higher
f-numbers) or slower shutter speeds. [L80] is equivalent to ISO 80, [L100] to
ISO 100.
[L80] and [L100] are available at all exposure step values.
[L80] and [L100] reduce dynamic range.
