Lumia, best photos in low light… and with backlight too

Best Photos

Lately it’s easy to notice that Nokia has been changing their strategy to focus greatly on mobile photography, as a way to differentiate themselves from other handsets in the market, with their Lumia brand. A strategy that is working out well in their favour, especially their development in the low light imaging sector.

Nokia and Microsoft have been taking advantage of this, both in their advertising campaigns and as method to win an explicit differentiation point of what it means to posses or not posses a Nokia Lumia Smartphone. But apart from that I’m going to show you that there are even more reasons why you should get one of these new devices available on the marketplace today.

Nokia Connects gave me the opportunity to test out the Nokia Lumia 720 for a couple of weeks and during this period I didn’t hesitate to conduct an experiment of its coolest innovation: a higher focal ratio than any other Lumia device available in the market, which means more light can get into the sensor.

The f-number or focal ratio (N), as it’s called in optics, is just the ratio of the focal length to the effective aperture (F). This dimensionless number results of dividing the focal length (f) and the diameter of the entrance pupil (D). The Lumia 720 features a focal ratio of f/1.9, as a reference the Lumia 920 has f/2.0 and the Lumia 1020 has f/2.2.

Owning my own Nokia Lumia 920, I opted to do a little research on the actual effect of this little focal ratio change during one of the most extreme conditions of light in the photography world: backlight. Here’s a set of photos I took during my research, including their original format, where you can see in detail the result (920 left, 720 on the right):

If you still have any remaining doubts about how much difference 0.1 less in the diameter of aperture to the light-gathering in the Lumia 720 can make, you should visit my Flickr photostream to view more photos. With no effort at all, it’s very easy to see that the 8.7MP PureView of the Lumia 920 wins over the resolution race against the 6.7MP of the 720 sensor, but the colours look much more well-defined and realistic in the 720 case.

Take into account that both sensors are backside-illuminated, which allows for the gathering more light than any other non-Lumia device, advantage in particular more visible with low light pictures, but the last of my photos also shows the difference made by a slight coloured close up instead of a total black one how it would happen in other cases.

I would love to hear your opinion. What advantages do you find in these types of technologies? What is your experience? Feel free to comment below. I hope you find this article useful.

Until the next time.
