From the first pic with the dark car, it seems that theres three possibities (K850 wise) 1. Xenon flash was too weak to illuminate the subject (Normally it works better than LED,seriously for Xenon flash it illuminates very well in a range) 2. Camera ISO level was set too low, sensitivity towards light decreased. 3. Exposure value decreased The second pic shows a blurred women 1. The shutter speed wasn't fast enough to capture the motion of the moving women/man (probably man) 2. Solution would be to increase the ISO so the that shutter speed would be increased but this might increase image noise. (Since we can't adjust shutterspeed in K850) Terms here : Lower ISO - sensor sensitivity towards light decreased , lower image noise. Higher ISO - sensor sensitivity towards light increased , higher image noise Shutterspeed - how long the sensor is exposed to incoming light This post has been edited by carbon14: Apr 27 2008, 04:38 PM

As you can see, the exposure time for the first image was very short indeed (1/250), the sensor did not receive enough incoming light. Taking in consideration fixed aperture, the higher ISO setting did not compensate enough for the fast shutter speed (1/250) 2. The second pic, exposure was significantly longer than the first one but the shutterspeed was slowed down to (1/6) 3. Both pictures had their exposure value or light value set to default "Exposure Bias: 0/100 EV". Increasing this would in turn allow more light in but the camera sensor will calculate then, different shutterspeeds and ISO for that compensation in exposure. I think the users of K850 should know that sometimes, auto mode just doesn't give the shot that we want eh? This post has been edited by carbon14: Apr 27 2008, 11:56 PM

Create a folder for the tracks (album name or artist) then put the album art into the folder in jpeg format by the name "folder.jpg" without the quotes.

Right I shall tell you some, but the users here should be more familiar with it. 1. Dust getting inside the camera lens 2. Unable to be hacked yet, modding acoustics and all. 3. Touch Softkeys doesn't activate sometimes 4. Picture quality...Well you be the judge for yourself Why do i know this? I researched the K850, I was battling with two phones to purchase. The K850 and the P1i,in the end it was the P1i

The N95 does more post image compressing and making the photos lose more detail. If you take a look at the N73ME photos, you can see very unnatural and overexposed colours. Not being a SE fan or Nokia-hater here, I think Nokia has to brush up on its image processing algorithms. BROD - Blue R*** Of Death ?

Getting Started Junior Member 284 posts Joined: Dec 2006 From: Ipoh	QUOTE(Redundant @ May 1 2008, 01:02 AM) just my oppinion, N82 has better image quality due to its bigger carl zeiss lens. it gives better colours and produces less noise when compared to k850i; It is actually strictly speaking, dependent on the sensor size albeit quality too. I was commenting on a photography thread about this Carl-Zeiss lens which Nokia is truly making us believe that they manufacture that pricey branded lens on their MASS PRODUCED camera phones. Come to think of it, has anyone fallen in for the branding war of Cybershot VS Carl-Zeiss? I don't want to be labelled as a SE fan here but the Carl-Zeiss lens is a well thought countering technique by Nokia. The Cybershot branding that SE established over the years and making buyers say CODE A :Hey both our phones are 3.2MP/5MP, but who's better in quality? B :I think yours is surely better because its a Cybershot. Now they go CODE A :But mine has a Carl-Zeiss lens inside! B :Yeah hor...

There is no such thing as Cybershot technology. Cybershot is just the brand name for Sony's camera. The only similarity SE Cybershot phones share with Sony's Cybershot Camera's are the Best Pic feature. Other than that, focusing, AE metering, color balance, etc etc algorithms are all device specific. Developers may get tips from Sony's Cybershot dept but they certainly need to come out with their own alogrithms simply because the hardware is so different. Same goes for Carl Zeiss. Carl Zeiss is just a brand. The lens on Nokia phones are of much worse quality compared to Carl Zeiss Lens made for SLR cameras. As far as lens goes, SE used some pretty bad lens on K850i which cause mild purple fringing. Previous SE Cybershots didn't suffer from this. However, Nokia's Carl Zeiss on N73 suffered from mild chromatic abbreviation and lens flare. Third is sensor. Not much info on the sensors used in Nokia and SE phones so can't make comparison. Noise levels seem similar. Fourth is image processors. All Nokias suffer from over saturation, enhanced reds, and over noise reduction. SE does quite well in this dept. Then there are the Camera's internal algorithms that decides exposure, ISO, shutter speed. SE and Nokia does equally well with the exception of N73 which uses a mechanical shutter. Got abit of pro and cons when it comes to capturing moving objects. I concur with this statement. And yes Cybershot isn't a technology its a brand. That goes along with Carl-Zeiss too. A branding war and us consumers caught in the crossfire.
