But lagfree is also nice

EDIT:

Using lagfree now.

I have the smallest lags with that governor. Well, performance has even less but that can't be a daily driver

Ondemand or Smartass is the most lagfree and power conservative trade off.

Especially if you set ondemand with "up threshold" to 70 instead of 90.

[Nokia Lumia 900] yipcanjo:
I've had my Lumia 900 since the pre-order availability date, so I've "kicked the tires" for a week and a half now. I love the phone, to be honest. The build-quality is great, the design is fabulous (in my opinion), it's the first phone I've owned that didn't require MAX volume to have a reasonable phone call, and the list goes on. I *really* like this phone. A lot.

That said, the camera has......issues -- and mainly with "focus", as far as I can tell -- perhaps also with white balance. Is everyone else seeing this? I returned to the AT&T store, tested an in-store phone (black, instead of cyan, which I have) and the issue was the same: open the built-in camera app, press on the screen to focus on something, snap the photo, and it comes out slightly out-of-focus. Strangely enough, the front-camera doesn't have this issue.

Wow.

Fortunately, it appears to be a "software issue", since I was able to grab another camera app -- SophieCam (which is pretty cool) -- and take *great* photos from the exact same phone. Here are two examples -- and in both cases I touched on the top of the shifter knob so that that would be the focus point.

(Taken with the built-in camera app. You'll notice that it appears to focus on everything *except* for the shifter knob, which is what I selected as the focal point.)

(Taken with the SophieCam camera app. You'll notice that the shifter knob is *very* much in-focus, and looks great -- aside from being grubby ;) )

So...is everyone else seeing this issue? Any fixes for it, aside from waiting for Nokia to resolve it? Thankfully, I trust that Nokia *will* fix the problem...but I hope it doesn't take too long. It seems that others are reporting this on Nokia Support, but my photos are a far cry from the awesome ones posted on this page.

Please...hurry up and fix this, Nokia!
[Nokia Lumia 900] moorent:
links aren't working for me
[Nokia Lumia 900] yipcanjo:
Sorry...fixed the images not showing up.

You'll also note the blue-ish tint in the first photo, and the more "natural" look in the second photo (taken with SophieCam). The second photo is more true to what it should be.
[Nokia Lumia 900] shea-bird:
second pic is 1000x better. its amazing that universal software comes out better than the "finely tuned" nokia camera software...what a joke! can u snap some more pics with that sophiecam? I am on the edge of buying a 900 and the camera is my biggest concern at this point!
[Nokia Lumia 900] slpin:
you do know there is a "macro" mode for taking close ups on the stock camera app....
[Nokia Lumia 900] mdintx:
To the OP: does SophieCam allow you take pics at 8mp?
[Nokia Lumia 900] mercx:
I absolutely agree that the camera appears to have issues on the Lumia 900. Compared to my Samsung Focus S, both the front and rear camera on the Lumia 900 are awful. I'm assuming that this is a software related issue as well. Comparing the built-in camera software between the Lumia 900 and the Focus S there are a lot of things that appear to be missing or that just don't work in the Lumia 900.

Here's one for you...

Open the camera and try changing the ISO setting... Does anything actually change for you? I see the phone blink for a second but the ISO level NEVER actually changes. The white balance also doesn't appear to be working quite right. Most of the test pictures I've taken appear to be more red then I think they should be.

I'd like to know what others see when they do the following...

Open the built-in camera app and zoom in all the way on an item and what do you see? I can tell you that when doing this on the Lumia 900 that I have the image is horrible blurred/pixelated (even after focusing). Now I know its digital zoom and I understand what that does but compared to the Samsung Focus S the image quality is horrendous. I'll post pics below for you to see the comparison of full zoomed between the two phones.

Nokia Lumia 900 - Full Digital Zoom 1

Samsung Focus S - Full Digital Zoom 1

I have uploaded more pictures comparing both full digital zoom and ISO levels between these two devices on my server at the link below.

[Nokia Lumia 900] foxbat121:
The built-in camera app is actually part of WP7. Nokia merely supply drivers.
[Nokia Lumia 900] mercx:
I agree and I would think the same thing, but apparently each vendor has the ability to "customize" the built-in app to some extent.
[Nokia Lumia 900] foxbat121:
Camera app is the one that has very little customization room for venders. In fact since the 3rd party app is working fine, it means the driver is ok and what's wrong is probably in the latest 8117 OS build.
[Nokia Lumia 900] yipcanjo:
Here are a few more photos...

(Normal mode, built-in camera app)

(Macro mode, built-in camera app)

(SophieCam camera app)

Strangely, the "normal mode" photo with the built-in camera app performed *fairly* well in this case, but the SophieCam snapshot is noticeably better.

To answer a couple of other questions:

1) YES, I know what macro mode is, and these pictures didn't require that. I would appreciate it if you'd give other forum members the benefit of the doubt that we're not complete idiots.

2) While SophieCam is free, it does not appear to take photos in full resolution. Bummer. That said, it's fun to use, and is really intended as an Instagram-type photo app -- quickly uploading "filtered" photos to Facebook, Twitter, or Flickr.

I do wish I'd done more testing before the latest update, since I don't know if things have gotten worse or better since. I'd also like to know how widespread this issue is. Everyone? Just some? Earlier phones only?
[Nokia Lumia 900] yipcanjo:
"Yes", it's discouraging to see camera issues at this point, but I'm hopeful about two things: 1) it's only a software issue, since another camera app can take wonderful photos using the same hardware, and 2) Nokia *will* fix this problem. They actually care about supporting their phones, supporting the camera quality, and they know that the company is riding on a successful WP7 rollout. They WILL make this right. Question is...how quickly?
[Nokia Lumia 900] ragingclue:
Umm there was a post either here or in a review where they determined Macro is a must even when not taking close-ups, and had various other recommended settings. I entered those and my pics have been better since then. All pics seem to be more in focus with Macro on. I know it shouldn't be that way, but it seems to be at the moment.

I should mention I haven't yet taken any true Macro pics though, so I can't speak for those.
[Nokia Lumia 900] go0gle:
you guys should tweet Damian, he is head of imaging @ Nokia and he e a really cool guy.. always responds to camera problems. I am sure they are working on a some camera updates. The hardware in the L900 is capable of more, than what the software allows it to be right now.

http://twitter.com/#!/phonedaz

The problem for Nokia is that they have to switch from their own platform where they have full control, to a controlled OS where they don't have the access, nor the expertise to make a real difference, at least not yet. It will take a while.
[Nokia Lumia 900] phonejunkie30:
I never thought of that makes sense.

Sent from my Lumia 900 using Board Express
[Nokia Lumia 900] yipcanjo:
Hmm. I'd be interested to know what the "secret settings" are to make things look a bit better. Any chance you could find that thread and report back?

I don't have a Twitter account -- and I'm not going to create one just for this -- but I'd certainly appreciate it if someone else could send him a tweet, maybe reference this thread, and then see what he says.

Yes... Nokia doesn't have the control they used to, but we're not talking about being BETTER WITH THE CAMERA than everyone else (like we know Nokia ought to be), we're talking about simply taking nice-quality photos without having things focused incorrectly. The Lumia 900 *ought* to be able to do that right now, and it just doesn't. Yes, they'll fix it, but it shouldn't be an issue at all.
[Nokia Lumia 900] yipcanjo:
Here is another related thread from Nokia Support. Specifically, they talk about the camera "trying to focus", and then bumping back to some sort of preset. I've seen this *exact* behavior, as the camera appears to focus properly, and then just before taking the photo it either bumps OUT OF FOCUS or decides to focus on something else entirely. Very strange.
[Nokia Lumia 900] Lmuggs:
That's exactly what I notice also. The picture looks great on the screen then when I go to take the picture it bumps out of focus. Frustrating...
[Nokia Lumia 900] ragingclue:
Ok the link was posted by XDA user shiftF7 in this thread here. Specifically this post.

The link goes to his review here.

Also, I've normally found if people figure out what ISO and Exposure do and how it relates to the photos they're unhappy with, they can make situational adjustments. That's not going to help the auto-unfocus issue and general graininess of Marco distance photos, but maybe it can help for the time being until Nokia comes out with a tweak in an update, which I'm sure won't be far away. My pictures generally do look better after reading that thread. YMMV
[Nokia Lumia 900] go0gle:
Done. I will post here if he responds.

And ya, it sucks that the camera app/drivers are not doing a good job.. at least we know it isn't the hardware, which would be worse.

Here is GSMarena's take on it, they are usually pretty good when it comes to camera testing..

http://www.gsmarena.com/nokia_lumia_900_att-review-748p5.php

"The Lumia 900 captures decent photos with accurate colors and good contrast. The amount of resolved fine detail is not among the best we've seen and there's also lots of noise when viewing the photos at 100% zoom. Still, the Lumia 900 has accurate white balance and the dynamic range is as impressive as it was on the N9 and the Lumia 800. As a result, images from the camera look pretty well when not zoomed at 100% so if you are not pixel peeping as we are, you will be perfectly alright with what comes out of the camera"
[Nokia Lumia 900] jimski:
So then "sucks" may not be an appropriate word when describing the L900s camera. "A little off" might be more accurate. Give them a few weeks to set things right.
[Nokia Lumia 900] DZWAY007:
Wow, those photos with Sophie Cam look really good. I to am having problems with the quality of Pics. It seems at if the focus and exposure looks good right before the pic is taken then it changes!?. Where do you get Sophie Cam? I looked in the marketplace and did'nt see it. And how does it work?. Any answer is highly appreciated and thanks in advance.
[Nokia Lumia 900] yipcanjo:
I don't know which part of the world you're in, but you *should* be able to find the Sophie Cam app in the marketplace. Here's the link for the WindowsPhone.com marketplace version: http://www.windowsphone.com/en-us/apps/19c8f96a-0505-4f8c-819d-f55374c9a70f

You can also try searching for "Sophie" via the marketplace on your phone. That should find it.
[Nokia Lumia 900] yipcanjo:
Thanks for posting to his Twitter feed. Hopefully it'll get this issue noticed (if it's not already).

Meanwhile....I'm bummed about this issue, but thankful that it's just a software glitch, and not hardware. Using other programs, it seems that the camera is VERY capable -- even compared to my friend's iPhone 4S earlier today -- so that bodes well for Nokia really getting this dialed in down the road.
[Nokia Lumia 900] 1orka:
They're too diplomatic, not to mention, they didn't test in indoors/low light conditions (real life scenarios), may be then "crap" would be even more appropriate word.

I don't believe in "magic" s/w update. THis "s/w update magic" looks more like "damage control" from Nokia. Obviously, judging by lots of noises and lack of detail, this phone has small sensor, hence low sensitivity in low light. H/w issue.

Probably they tried to save costs, and i hate Nokia for that.

Here is N9 engadget test, mentioned in some other thread, same camera as in Lumia 800/900.

http://www.engadget.com/2011/10/22/nokia-n9-review/

Seems like they came to same coclusion
[Nokia Lumia 900] arcspeak:
Hey, check out this feature!

Hey, I just found a cool feature of the built-in camera software.

If you press the camera button to take a picture, it focuses on the center of the frame, and adjusts the exposure according to the meter setting, which is center-weighted by default (see first image)

If you touch the screen to take the picture, it focuses on that point, and adjusts the exposure for that point. In the image below, I touched the screen at framed photo on the left (see second image)

And in the third image below, I touched the screen on the face of the brick building outside.

I'm impressed with how well it can handle really tricky (bad) lighting.
[Nokia Lumia 900] go0gle:
I very much doubt that pixel size from the L900 sensor is smaller than 1.4µm, which is exactly the same as the iPhone 4s and the Galaxy S2 @ 8Mpix. Most smartphones use "off the shelf" sensors, so its up to the optics and the jpeg processing to do a good job after that. The iPhone 4s uses the same sony sensor that you find in the Xperia Arc/Neo, but it has better optics, and better jpeg compression algorithms = better results.

I doubt that Nokia are using 1.1µm pixels .. no way.

The N8 uses 1.75µm pixles, combined with good optics and good software.. it works.

So, i think that if they can manage to get the maximum (using better software) out of the sensor/optics combination in the L900, we will see better results.

edit.

I did the math on it, and it is indeed 1.4 microns.

L900 shoots @ 3264 x 2448

As far as I know, the sensor is from the N9, which is: 1/3.0" (4,8mm X 3,6mm) http://en.wikipedia.org/wiki/Nokia_N9

There are 1000 microns in a mm

4,8 X 1000 = 4800 across the width of the sensor 4800 / 3264 = 1.470*** microns per pixel.

depth of field seems to be ok in macro mode
[Nokia Lumia 900] epidemike:
Thanks for all that math, that was a great post.

Thanks for all that math, that was a great post.
[Nokia Lumia 900] 1orka:
I know that, but didn't they claim how good Lumia optics is prior to its release? I think it was that Damian guy, they kept quoting him almost daily, now he is surely silent on Lumias and talks (a little) only about 808 :mad:

And all those phones you mentioned still have better cam than Lumias, so that only proves my point.

And you doubt based on what? I could understand doubts if pictures were really good, but this isn't the case. I see sudden drop of sensitivity in indoors conditions, lots of noise in evenings, my opinion (and not only mine actually)is that this is sensor limit.

As for Iphone etc, well, unlike Nokias (Lumias included) Iphone has BSI sensor, which are more sensitive than conventional sensors which Nokia use, so you can't just compare them by size, BSI still has their advantage.
[Nokia Lumia 900] go0gle:
I am not trying to justify their poor performance. I just think that there is more potential in the hardware, that can be unlocked with a software update.. how much ? No way of knowing that.

And I said that i doubt Nokia are using smaller sensors than the 8Mpix standard, which seems to be 1,4 microns, and IF the sensor is indeed from the N9, I ma right and they are using 1,4 microns. I am really interested in what HTC did with the Titan 2 .. 16 megapixels, the sensor must be bigger, or we are talking 1,1 micron pixels.

You might be right about the optics, they might be bad, but I don't see why that would be the case considering that they are probably the same as the ones in the Nokia N9, which are quite good.

As far as BSI.. it still can't make up for naturally bigger pixels. Otherwise all the mirror less DSLRs will be using the technology. But it probably helps a bit.. if it was that much better, the iPhone 4s should take better photos than the N8, and that is not the case for the most part, the N8 still has a wider range (different conditions) of effective use.

Like I said, most smartphones use "off the shelf" camera modules.. very rare you would see optics and a camera module specifically designed for a specific smartphone. The 808 and the N8 are exceptions ... also the iPhone 4s seems to have special optics on board as well.
[Nokia Lumia 900] DZWAY007:
I Searched Marketplace by phone and could not find it. But I found it on PC searching apps for Windows Phone on ZUNE. I cant believe the difference in quality with Sophie Cam. Its night and day. Took shoots in day light, indoors, outdoors, poorly lit rooms. All to the shots with Sophie Cam were superior to shots shot with the Lumia 900 with default settings. Even the way it focuses and take pics are different. This really leads me to believe that its something in the software/drivers/settings in the phone and not the hardware. I really hope this is the case, because I love everything about the Lumia 900 except for the uncertainly of the camera. Thanks for the info yipcanjo
[Nokia Lumia 900] sifusky:
I noticed my camera is bad at low light and when I turn on light, it takes a long time to catch on..makes the iphone camera look extremely advanced..cmon nokia!
[Nokia Lumia 900] awesomeindeed:
I'm having these issues as well. I came from an HTC Titan, and I've compared photos I've taken in good lighting, low lighting, no lighting, and the Titan's camera beats it in all of them hands down. I hope Nokia figures this out. My phone is my main camera, and pretty much every photo I've taken with this phone has been blurred or has a ton of noise. :(
[Nokia Lumia 900] ragingclue:
Are you guys just leaving the camera on default settings and taking pictures and then deciding they're bad, or are you at least playing with the settings before throwing your hands in the air?

The camera needs a lot of tweaking on the lower level, I'll agree, but there is a certain amount of burden the user should bear in working within the domain of settings which they were given at the higher level.
[Nokia Lumia 900] awesomeindeed:
To be fair, default settings should be good enough to take a picture that's in focus, especially when you let the phone use its auto focus feature. I've found that to not be the case with this phone. Almost every photo using the stock camera will come out of focus right before the picture is snapped, at least that's the case on my particular phone.

I'm not a total noob with phones or with cameras, but I find this behavior pretty unacceptable with camera hardware like this, especially when I have another WP device sitting right next to it that has zero problems in all of the same situations without tweaking any settings.
[Nokia Lumia 900] ragingclue:
Don't get me wrong, I do agree with you; however, I was just emphasizing that messing with the settings has made it bearable for me for the time being. I had much higher hopes for this camera, and I expect an update to bring it up to par, but for now people have to play the cards they were dealt. Some people don't bother to mess with the settings before giving up on the camera completely. I'm sure a fix will come, so for now we'll just have to tweak as much as we can at our layer until Nokia/M$ fix whatever is wrong.
[Nokia Lumia 900] alodar1:
I respect that the problems you are pointing out are valid, without question. I have a hard time trying to make any of them a reason to downgrade the Lumia 900 though. Of all my requirements for a phone, any thing more than a quick shot camera, is not amoung them. I wonder how many people actually feel the same way.

In looking at your examples and following explanations, I can agree, the camera is not idea. But I would have never noticed any of those things without reading about them here on xda. I've taken several quick shots with my 900 and shared them on facebook. None can be confused with with anything Vogue like. But they more than suited my purposese.

Do you guys really expect to take Masterful pictures with something you slip into your pocket? Or, is this really just a discussion point, and you're going to live with the camera in hopes it gets an upgrade?

I had the Dell Venue Pro when it came out. That camera was close to unusable when it came out. A resulting patch improved it greatly. But, these kinds of discussions still occured afterwards...

I guess its about priority. I use my phone for lots of things....but ...mostly, never a camera....strange.
[Nokia Lumia 900] awesomeindeed:
Well, honestly, the camera is a touted feature of the phone. You may not use it, but I'm guessing a lot of people do. Snapping quick pictures is the extent of most peoples' use of the camera I would imagine also. However, it's a shame that with the optics used in said camera it takes subpar images compared to other competing devices.

Not the end of the world for sure, as I use my phone for many other things, but it's frustrating when something that should be a basic functionality requires extra tweaking and input on the part of the user. It turns snapping a quick pic into a task, which is something that WP itself touts as something you don't have to put up with anymore.
[Nokia Lumia 900] alodar1:
And I do agree with you. But...basic functionality...I don't consider optics when I slip it in to my pocket. So I don'tconsider its bad. If I look at the pictures in this thread, I see good and better....not bad and better. If I pull out my Nikon, they all suck. So thats the perspective I have. Of course...I'm not any better with the Nikon..so its all good.
