With Manual Controls, you can use the touchscreen on the Lytro camera to set the shutter speed, ISO, ND filter, or turn on Auto-Exposure Lock. Manual Controls provide not only straightforward benefits like the ability to brighten up a dark scene, but also allow for more creative and artistic techniques like painting with light.
To access Manual Controls, swipe up on the touchscreen and touch the "gear" icon. Then, scroll down the Menu, and touch to enable the "Manual" option:
Techniques like painting with light, and night or low light landscapes benefit from long shutter speeds, while faster shutter speeds allow you to limit motion blur when light conditions permit (in brighter light).
Control light sensitivity to limit motion blur within brightly-lit compositions at the minimum end, or make the most of limited light (especially useful when you are able to steady the camera) at the maximum end.
ND Filter Toggle: Neutral Density Filter engaged (-4 equivalent f-stops) - disengaged (no effect).
Toggle the ND Filter to achieve an intentionally underexposed or blown-out look, or to keep the camera from adjusting itself while you compose your shot.
