This is a bigger delay than we're used to see from modern phones. Unfortunately, the Lumia 920 is not the fastest shooter around and it takes a couple of seconds before a photo is taken and the camera is ready for the next shot. The shutter key will wake the phone up with a single press and launch the camera app. The flash can be set to auto, forced or off. You have a dedicated Macro focus mode but no face detection.

The camera app on Windows Phone offers extensive settings, ranging from scenes and effects to white balance, contrast, saturation, sharpness and ISO among others. On the left you have an arrow that takes you to the images taken with the camera, alternatively you can do a swipe gesture too. From top to bottom they are the still/video camera toggle, front/back camera toggle, flash mode setting and the Lens button.
The camera UI is pretty simple - you have your viewfinder and some controls on the right. The difference between 4:3 and 16:9 photos Most other cameras simply discard info from the 4:3 sensor to make it produce a 16:9 photo and lose 25% of the resolution. It snaps photos at 3264 x 2448 resolution in 4:3 mode and 3552 x 2000 in 16:9 mode (only 11% drop in resolution). Instead, the Lumia 920 has that clever multi-aspect 8.7MP imager (1/3", µ 1.4 pixel size) that we know from the Nokia N9. The technological achievements behind the stabilization system gave Nokia enough grounds to market the smartphone as PureView even though it doesn't have the huge 41MP sensor of the Nokia 808. Keep in mind though that while the OIS works great for static scenes, moving objects in low-light scenes might still turn out blurry due to the slow shutter speed (motion blur). That, combined with the f/2.0 aperture, leads to class-leading low-light performance. This has obvious advantages during video recording, but it also allows the Lumia 920 to use slower shutter speed in low-light conditions without fearing that camera shake will ruin the photos. The way it works is a gyroscope detects the motion of the phone and the whole optical assembly moves in the opposite direction to cancel out the movement (e.g. The Lumia 920 has a 26mm wide-angle lens by Carl Zeiss and a dual-LED flash, but it's unique in the mobile phone world - it's the first one to feature true Optical Image Stabilization (OIS) instead of digital tricks that try (and fail most often than not) to achieve the same result.
