The launch of a new cameraphone boasting 41 megapixels has caused a stir on its launch. But how many megapixels do people need?
Nokia’s 808 Pureview has dramatically upped the ante on the number of megapixels on a cameraphone. Many smartphones today, like the iPhone 4S, have an 8MP camera.
Now Nokia has blown that standard out of the water. But are megapixels the key thing for consumers to focus on?
Photography enthusiasts have been warning about the “megapixel myth” for some time. In the myth, more megapixels means a better camera and a better photograph.
But that is not necessarily the case.
Damien Demolder, editor of Amateur Photographer, states that at first glance 41MP seems “ridiculous”. Professionals doing billboard photography use 25MP cameras. For people wanting to share holiday snaps online, 8MP is more than enough.
But Nokia states people are missing the point. It is the way the pixels are used that is the real “quantum leap”, a spokeswoman says.
The information from up to seven pixels is combined to create a new, single, better pixel, in a process termed “oversampling”. The company likens it to how compact discs decode more data than needed so they can retain better quality data or information.

The 41MP figure will get people excited but that is not really what this is about, states Nate Lanxon, editor of wired.co.uk. “People will think ‘wow’ this is better than a digital SLR [single lens reflex].”
He argues the camera will still produce photos at eight megapixels – but they will be sharper. “It’s really about making better use of the available light and using software to enhance it further.”
Nokia for its part, states the 41MP sensor will grant enthusiasts to be creative in zooming, reframing, cropping, editing and resizing without loss of detail. A smart function on the phone will reduce file sizes, making it simple to share and store the photos while preserving the detail, Nokia says.
Demolder argues the massive zoom will be “quite useful” for some users. Few cameraphones have an optical zoom lens – those that do tend to be clunky and look strange, he says.

We know that more megapixels do not mean a lot if the technology behind it – notably the sensor – is not up to much.
But Nokia has been showing off images shot on its new phone blown up to poster size, and they look pretty good. What’s more, it shoots in full 1080p HD video, so with one of these rather hefty handsets in your pocket, you should have everything you need to shoot quality images on the move.
But the phone – for all its high-end technology – feels like a solidly made Nokia from about five years ago. Back then it would have sold by the million. Now the world has moved on and smartphone photography is all about apps.
Cameraphones have such little sensors – about a quarter of the size of a fingernail – that to group 40 million pixels together means they will be extremely small. Image quality – even with the clever software – will be no match for a digital SLR. “Even on a bright day there’ll be grainy bits in the sky when you blow it up big,” Demolder suggests.
And Lanxon states that cameraphones are increasingly about sharing. Nokia’s new phone runs on the Symbian operating system, which is “far less capable” when it comes to apps than Android, Apple or Windows devices.
The megapixel race will not go away. But Demolder doubts that other manufacturers will feel the need to chase the 808 Pure View.
The Nokia 808 Pureview will cost roughly 450 euros but has no launch date yet in the UK.
The USP (unique selling point) advantage will not be in proportion to the technological leap or probably the cost, Demolder believes.
“Most people would find the zoom useful, though few will know they have it, fewer will discover how to work it and fewer again will remember to use it.”Details :
