When Samsung rolls out the Android 5.1 update to the Samsung Galaxy S6 and Galaxy S6 edge, users will find a new camera feature that should make it a little bit easier to grab a great shot in challenging light conditions. Similar to a feature found in Apple’s camera app on iOS, users will be able to vary the exposure setting dragging their finger on the screen. What will make this extremely useful though is that the adjustment can be made while the user is preparing to take the picture and they will see a live preview on their screen.
Probably the two biggest uses of this feature will be when shooting a poorly lit scene or when shooting something with lots of backlight. In the case of low light situations, users will be able to lengthen the exposure to brighten things up while framing their shot. Likewise, when shooting a subject with lots of background light that may be fooling the camera sensor into shortening the exposure leaving the primary subject underexposed, users will be able to fix that before ever taking the shot.
Adjusting exposure in post-processing is nothing new, but this feature will help users avoid that additional step. It also means users can take proactive steps to make sure they capture all the detail they need. Samsung is expected to roll out some other new camera features in June when Android 5.1 is released, including shutter speed control. So we should see even better shots from users who know their way around manual camera settings, although most users should benefit from the touch-based exposure control.
