Though the Nokia Lumia 900's camera does have a macro mode, the phone didn't do as well as the HTC Titan II in extremely tight closeups. For example, the chip in the lower-right corner of the image isn't quite sharp enough.
Outside, the Nokia Lumia 900 fared better than it did with the indoor still-life shots. Even so, the frosty colors and bluish tint were an issue outdoors, too. Colors of flowers in this image snapped in warm sunlight have hues that look too cold to my eyes.
The Nokia Lumia 900's lack of HDR became apparent in shots like this of the iconic New York Flatiron building. Details such as windows and textures in stone are very dark, especially when compared with the HTC Titan II's images of the same location.
With the HTC Titan II's ISO settings manually set to ISO 100 for the still-life test shot, the result was very similar to the phone's automatic ISO selection. This indoor image has lifelike color and crisp details.
The HTC Titan II sports an image sensor capable of going up to ISO 1600, and images shot at this setting surprisingly have less color noise and artifacts than those taken with the Nokia Lumia 900 at a slower ISO 800.
Though the sky was a little blown out, the HTC Titan II snapped an impressively detailed image of the Flatiron building. Here it's light enough to make out more of the bricks and even air-conditioning units along the building's walls.
