Nokia's 808 Pureview: How many megapixels do people need?

Nokia's 808 Pureview has significantly upped the ante on the quantity of megapixels on a cameraphone. Numerous smartphones today, just like the iPhone 4S, have an 8MP digicam. Now Nokia has blown that standard away from the water. But are megapixels the key issue for shoppers to concentrate on? Photography enthusiasts have been warning concerning the "megapixel myth" for many time. Inside the myth, much more megapixels suggest an improved digicam and a better photograph. But that is not actually the case.

Damien Demolder, editor of Novice Photographer, says that at first look 41MP seems "ridiculous". Experts doing billboard photography use 25MP cameras. For individuals eager to share getaway snaps on-line, 8MP is more than enough. But Nokia states people are missing the point. It is the way the pixels are used which is the real "quantum leap", a spokeswoman says. The information from up to seven pixels is mixed to make a brand new, one, far better pixel, within a process termed "oversampling". The company likens it to how compact discs decode more data than necessary in order that they can retain far better high quality information or information.

The 41MP determine will get individuals excited but which is not truly what this is about, claims Nate Lanxon, editor of kingdom. "People will feel 'wow' this is better than a electronic SLR [single lens reflex]." He argues the digital camera will still produce photos at eight megapixels - nevertheless they will probably be sharper. "It's really about creating much better utilization of the accessible mild and utilizing software program to enhance it additional." Nokia for its part, states the 41MP sensor enables fanatics to become inventive in zooming, reframing, cropping, enhancing and resizing with out lack of depth. A smart function on the cellphone will reduce file dimensions, which makes it easy to share and store the pictures whilst preserving the depth, Nokia says.

Demolder argues the big zoom will likely be "quite useful" for some consumers. Couple of cameraphones have an optical zoom lens - those that do are typically clunky and search odd, he claims. Cameraphones have such tiny sensors - about a quarter of the size of a fingernail - that to group 40 million pixels collectively means they are going to be extremely small. Nokia counters that their sensor is in fact five occasions the dimensions of these used on 8MP cameraphones, therefore the pixels are the exact same size. But to the critics picture high quality will probably be no match for a digital SLR. "Even on a brilliant day there'll be grainy bits inside the sky when you blow it up large," Demolder suggests. Nokia once again denies this, insisting that pictures can be blown approximately poster dimensions without turning into visibly grainy.

Lanxon claims that cameraphones are increasingly about sharing. Nokia's new phone runs on the Symbian running system, that is "far less capable" when it comes to apps than Android, Apple or Windows devices. The megapixel race will not disappear. But Demolder doubts that other manufacturers will experience the need to chase the 808 Pure View. The Nokia 808 Pureview will cost roughly 450 euros but has no start day but within the United kingdom. The USP (special offering stage) gain will not be in proportion to the technological leap or most likely the cost, Demolder believes. "Most people would discover the zoom helpful, even though handful of will know they've it, less will find out the way to function it and fewer again will remember to utilize it."
