Nokia Pureview 808

If you clicked the links and read about the phone, the primary thing you probably noticed was the camera. If you didn't, the cliffnotes are that it has a 41MP camera and uses a new technology that is called pixel oversampling. The idea is that you have more pixels than you actually need. The extra pixels are used to create one, much better quality pixel. This also gives you LOSSLESS DIGITAL ZOOM up to 4x!

I'm sure I'll hear why Nokia is crap and why Symbian is crap, but whatever. I've had Nokia's for 10 years, and have been using their smartphones for the last 8 years. My last phone was the Nokia N8. It was great, and I'd still be using it now if I hadn't gotten it wet and ruined it. (it still worked, sorta...)

Anyway, the main reason for my post is to share my experience with the camera. You can read about it all day long and watch Youtube videos and comparisons (which I spent hours on) but nothing prepared me for the image quality that this phone creates. It's made my dedicated camera COMPLETELY useless. Not to say that a DSLR wouldn't be better. It is better. But not by much, and I don't have to lug a DSLR around all the time.

So I won't bore you with my family pics from this weekend, but I do have a 1080p video I took of my brother-in-law falling down, LOL! I'm still editing it, but I'll get it up later.

The really fun thing I've discovered (and if you're into photography, you'll probably think I'm lame) is the "bracketed" feature. This is used to create images that you can use to create a HDR (High Dynamic Range) image. I had never heard of this, but I wanted to try it out. I had also purchased a tripod and phone holder when I bought the phone so it was pretty easy.

So here's how it works; You make some settings in the phone (if someone wants to know my settings, LMK) put it on the tripod, and hit the button. Depending on the settings you used, you'll get either 3 or 5 images at different exposures. Then you use a program to combine the LDR (Low Dynamic Range) images to get the HDR image.

This is my first try. I know the content is boring, but I chose it because of the extreme contrast between light and dark.
This is the first image that is at "normal" exposure
Image

Right after that, the camera takes another picture at a lower exposure
Image

And right after THAT, it takes another at a high exposure
Image

I then used THIS program to create the following image
Image

As I said, this is literally my first try at this, but I'm excited to get outside and start getting some better shots with this phone.

I'm sure there are other photography buffs on here that have WAY more knowledge than myself, so I'd love to get your input!

BAH! Stupid Photobucket castrated my image sizes. Bastards. I guess I shouldn't complain about free image hosting...

Wow. That phone has caught my attention before. Never knew it had a bracketing feature!

Symbian's not crap. It's just dying. :( And it's being replaced by the worst OS in the history of phones.

Copied from cnet:
packing a larger sensor with more than three times the number of pixels doesn't translate into better photos: smaller pixels collect less light, which worsens image quality. The thing is, Nokia doesn't really want you to use the full resolution of its sensor. Not for giant photos, anyway.

Instead, the 808 defaults to a 5-megapixel resolution. Through a process called pixel oversampling (though some might call it pixel binning), Nokia combines seven pixels into one superpixel. Doing that helps eliminate image noise in low-light conditions and, according to Nokia, makes noise virtually nonexistent when shooting in good lighting. So while the 808 can be set to take 38- or 34-megapixel images depending on the aspect ratio used--4:3 or 16:9, respectively--it's not why Nokia used such a high-resolution sensor.

The pixel oversampling also allowed Nokia to develop a lossless digital zoom, which is probably the most important part for a lot of people. Basically, as you zoom out the amount of oversampling reduces until you've reached the limit of the actual resolution. In other words, if you have it set for 5 megapixels you can continue to zoom until it's no longer oversampling and simply using a 5-megapixel area of the sensor. There is no upscaling or interpolation, it's just a 5-megapixel photo. At that resolution, it will give you about a 3x lossless zoom for photos and a 4x zoom for movies shot in full HD. Reduce the resolution, and you get more lossless zoom.
I guess that explains it all. The 41 megapixel sensor actually hurts the image, so you have to combine more pixels together to do the job better. Interesting stuff!

The light-field camera is a much cooler idea, however. They should have gone with that rather than this, IMO.

I am interested in what MoD thinks is the worst OS for phones...

I couldn't agree with this more. I know Symbian needed replaced, by WHY they chose to go with Windows Phone OS is disheartening (f*** you Mr.Elop). They should have stuck with MeeGo. I ALMOST bought an N9 out of spite, but it didn't have all of the features I wanted (I use the CRAP out of my FM transmitter that NOBODY else seems to use in their phones), and it makes Symbian look like iOS with regards to App support.

My brother in law actually bought the Lumia 900 when it first came out because he was so impressed with my N8 and thought he was getting a better phone. He returned it 3 days later and switch back to iOS and got an iPhone4S. It broke my heart a little, but I wasn't surprised either.

I read that article before I bought the phone, but I think they must have written that without having the phone in hand. I took a few pics at full resolution (no pureview technology being used at all) and the images looked just as good as anything I captured with my N8 (12MP, Carl Zeiss Optics, etc), only the file size and image were HUGE. I'm honestly not even sure what you'd want an image that size for, but it's there if you want it.

The light-field camera is nice, but trying to package it in a cameraphone would be next to impossible. There is a reason Cannon's version is long and skinny. You have a camera with 2 focal points. If you saw the size of this phone compared to today's super-thin phones (which I HATE BTW, #1 reason I didn't buy a GS3. I have huge hands and I can't hang on to the damn things.) you'd see how hard it would be to add MORE depth to have ANOTHER focal point.

What Nokia is doing on the soon-to-be-released Lumia 920 is another type of PureView technology. Instead of using the traditional Digital Image Stabilization that is on most phones (including the 808), point and shoot cameras, and even mid-range camera's, it's using Optical Image Stabilization. This is usually reserved for high end camera's. From what I've seen the image quality, ESPECIALLY in very low light, is astounding, better than my phone for sure.

I was contemplating trying to wait until it came out to buy another phone, but my poor "old" N8 was on it's last leg and I don't think I could have used it for another 3 weeks until the Lumia 920 came out to compare. Plus I'm used to Symbian and I don't want to switch OS's until I absolutely have to. Since this will most likely be Nokia's last high end phone to carry it, I decided to go this route. When the time comes (a few years from now I hope) to get another phone, I'll stick with Nokia and hope that they've dropped WP, burned Mr. Elop at the stake, and brought a new version of MeeGo back and it's booming in the market... That won't actually HAPPEN, but I can hope.

To clarify, the pics I've seen show the 920 has better low-light image clarity than my phone, but in full to medium light, the over-pixelization seems to work better and you get lossless zoom.

Maybe the next phone will have both, LOL!
