The Neutral Density (ND) Filter is a physical filter that, when engaged, reduces the intensity of the light hitting the sensor by 4 equivalent f-stops.
In normal Everyday Mode, the ND Filter will engage automatically when pointing at a bright light source. With Manual Controls, you can toggle the ND Filter on or off to achieve an intentionally underexposed or blown-out look, or to keep the first generation Lytro camera from adjusting itself while you compose your shot.
Here's how to toggle the ND Filter:
- Make sure Manual Controls are enabled (swipe up on the touchscreen, touch the "gear" icon, then from the Menu verify the "Manual" option is checked; touch the blue "X" to exit the Menu).
- Swipe down on the touchscreen and touch the "Shutter Speed" button.
- Touch the "ND" button to toggle the ND Filter setting.
- NOTE: If you do not already see the "ND" button option above the on-screen slider as shown, then select a manual Shutter Speed setting and touch "Set." Next, swipe down on the touchscreen again, but this time touch the "ISO Sensitivity" button, then select a manual ISO Sensitivity.
- If the ND button is white, then the ND Filter is disengaged.
- IMPORTANT: Be cautious when the ND Filter is manually disengaged while zoomed in on extremely bright light sources (e.g. lasers, commercial lighting, or industrial LEDs) for long periods of time.
