Light field manual. 
Taking a photo with the Lytro camera involves putting something in the foreground and finding something interesting in the background. Point, click, repeat. It’s simple, but it lacks the level of control many photographers crave.
On Tuesday, Lytro added manual settings to its line of cameras via a free firmware upgrade. Owners can now adjust ISO and shutter speed for their light-field photos. They can also control the built-in ND (Neutral Density) filter and lock the exposure of a composition. The camera lens is locked at f2.0, so f-stop adjustment is unavailable.
The most exciting of the new features is the shutter control. The speed can be adjusted from a quick 1/250 of a second to a full eight seconds. Grab a few lasers and glow sticks and spend the evening creating light-field light paintings to wow your friends.
Equally important but less exciting is the camera’s new ISO feature, which has a range of 8 to 3200. As expected, the higher up the ISO range you go, the more grain you add to a photograph. But thanks to the shutter-speed adjustment and the Lytro tripod mount, you can capture low-light situations without photographs looking like they were lightly sand blasted.
Along with the new manual controls, Lytro also introduced two new colors to help lure those considering taking the light-field leap. The camera is now available in Seaglass (green) and Moxie Pink. The later is available exclusively Target.
A 3D-image feature was demoed for a yet-to-be-announced future release. It’s intriguing, but Lytro made the right decision bringing manual controls to the camera first.
