Nikon 27629, 27631, 27619, S1 White, S1 Red manual ISO Sensitivity, 147

ISO Sensitivity

The higher the ISO sensitivity, the less light needed to make an exposure, allowing faster shutter speeds or smaller apertures, but the more likely the image is to be affected by “noise” in the form of randomly-spaced bright pixels, fog, or lines.

	The camera adjusts ISO sensitivity in response to
q Auto (100–6400)	lighting conditions. ISO sensitivity is adjusted in
x Auto (100–3200)	the range given in brackets; choose larger ranges
w Auto (100–800)	for increased sensitivity when lighting is poor,
	smaller ranges to reduce noise.
100, 200, 400, 800,	ISO sensitivity is fixed at the selected value.
1600, 3200, 6400
