Best smartphone Camera 2016:

We test the cameras of the latest flagship phones including the iPhone 6S Plus, Nexus 5X, Nexus 6P, Samsung Galaxy S6 Edge+ and more to find out which performs best for photos, videos, selfies, macro and selfies.

Four smart phonesWe set up each phone to the highest resolution available for photos and videos. That meant switching aspect ratio from the default if necessary for the front and back camera. We didn't use any RAW modes, just the standard JPEG mode. For each test, we took photos within minutes of each other to ensure conditions were as similar as possible. We didn't use any tripods, since virtually all photos are taken handheld with a phone. This meant stabilisation systems - whether optical or electronic - could prove their worth.

Indoor photo testAgain, opting for real-world shooting, we selected automatic modes and didn’t tap the screen to choose focus or exposure points. Few people do this and it allowed us to assess the cameras' automatic exposure systems. The tests are not scientific: we haven't used test images to check for focus, distortion and other technical characteristics. These are real-world photos, so they give the same results you can expect when you use the phone yourself.

All photos were taken from the same spot, which is why the field of view changes from phone to phone. Different cameras have different lenses: some more wide-angle than others. Also playing a major part is the sensor format. Some are 16:9 while others have 4:3 sensors. In each case, we made sure we used the highest resolution available – many Android phones default to 16:9 which chops the top and bottom off the photo for phones with 4:3 sensors.
The photos were all taken in November 2015 on an overcast day, including the selfies which were taken indoors, facing a window. They are unedited. All we did was to resize them to 1600 pixels wide and display them at 750 pixels wide. You can click on them to expand them to 1600 pixels. Check them out at now: TechAdvisor

Image Composite Editor - Free from Microsoft

Logo of Image Composite EditorMicrosoft Image Composite Editor is an advanced panoramic image stitcher. Given a set of overlapping photographs of a scene shot from a single camera location, the application creates a high-resolution panorama that seamlessly combines the original images. The stitched panorama can be shared with friends and viewed in 3D by uploading it to the Photosynth web site. Or the panorama can be saved in a wide variety of image formats, from common formats like JPEG and TIFF to the multiresolution tiled format used by Silverlight's Deep Zoom and by the HD View and HD View SL panorama viewers.

Imaging Resource's New Comparometer

Logo of image resources pageThis tool now lets you compare reference images from digital cameras side-by-side. These images are JPEGs straight from the camera, and were taken under carefully-controlled conditions, to provide valid comparisons of camera capabilities in actual shooting situations. By clicking on and zooming into each image, you are able to closely compare a variety of indoor and outdoor images or the test patterns provided.

You can also download the images (using your browser's "save image as" function) and output them on your own printer, to see how the cameras involved will perform in your application. (See the copyright notice first though!). Check out the Comparometer now...
