Detail, however, isn't the HTC One's strong point. This is where the fewer megapixels on offer work against it, as it doesn't produce anywhere near as much information as the iPhone 5 and Galaxy S4. If you regularly print or crop your photos, the HTC One won't do you any favours.
The camera has other issues, too, such as a bad habit of over-exposing, which frequently results in blown out highlights, and adding a bluish cast to colours, which makes them look less vibrant.
The main rivalry here is between the Apple iPhone 5 and the Samsung Galaxy S4. The HTC One certainly has its strengths, namely for macro, action and low-light photography, but its performance for day-to-day shots wasn't up to the same standard as its competitors.
The Samsung Galaxy S4 was able to produce a slightly higher quality of photos out of the three under optimal lighting conditions, but it lost its lead to the other smartphones whenever it was challenged with something trickier.
The Apple iPhone 5, however, was a strong contender no matter what we threw at it. It may have been runner-up for most shooting scenarios, but the consistently good performance across the board makes it the best smartphone camera all-round.
