    The problem here was exposure. Not sure why, but your Nexus shot was wildly overexposed. It wouldn't necessarily consider that a bad thing as over exposing without motion blur in a dim environment is actually tough to do unless you have a VERY good light gathering sensor.z

    The Nexus shot probably lacks detail more because it picked some really highISO to get the over exposure more than due to it's 5mp of pixels.

    I just did a test with the wife between her 8mp Charge and my 5mp Nexus. The nexus shots were much better.

    those pictures were taken to help me decide and i still havent. overexposed for sure, but by samsung, not me. would love to take them both out fior a photo shoot but i hate handcuffs!

    You're in two distinctly different locations, with different lighting conditions. It's an unfair comparison. Hardware can only make up for user error so much.

    And that's fine. If being equally careful with two phones isn't good enough and causes "user error", I'll be happy with the one that works better for me.

    Seems like a nice phone though. Didn't mead to hurt anyone's feelings.

    Actually the sensor is the most important factor in any camera. Go read up on Gizmodo/Engadget regarding this. 5MP is more than enough for a camera on a smartphone. If you really want "12MP" get a regular camera, these devices are never meant to be that high rez.

    It's not fine. Anecdotal "proof" isn't fine, nor has it ever been fine. The camera is good for the purpose of a camera phone, and that's all it needs to be. I understand the iPhone changed that, and people want that with Android-but there's still not a comparable Android phone that can push out iPhone 4S level shots-but still, i'd rather trade capturing the moment (speed with the Nexus) than never capturing it at all (iPhone 4S or any other Android phone).

    I have seen all these videos of the nexus camera having the ability to make peoples eyes look super big, or even the mouth. Anybody know where to find the option for doing this? I've looked everywhere.:confused:

    Don't have the phone and haven't played with all the camera features. However, if you don't see may want to quickly go grab Camera Zoom FX in the market. It's one of the .10 cent apps on the LAST day. May be worth it regardless, and I do see those features you are asking about in the app.

    Thanks, I found it. The options are only available if you are video recording.

    The key to understanding this matter is the pixel density on sensor, number of pixels per unit area (/mm^2 or /inches). Lower the pixel density, it's better because each pixel size is bigger and can receive more light. DSLRs have much larger sensor than P&S cams and phones. So it has lower pixel density compared to P&S with same MP, leading to low noise clean images. On top of that, it has high quality large aperture lens that can let plenty enough light to sensor at fast shutter speed.

    The limiting factor in phone camera is small sensor size like 1/7~1/8". Cramming 8MP into that size sensor is probably equivalent to 20MP or more in P&S camera sensor. No one in right mind in photography would want that. Of course 1MP or lower pixels will result in poor sharpness, low resolution. But bumping it way above sweet spot in pixel density will gain nothing in image quality and actually would hurt it.

    Are those the only two photos you took? I'd play around with that Nexus. I suspect it's set for center-weighted exposure and adjusted for the black display stand smack in the center of your photo. That's not to dismiss the camera -- for Point & Shoot functionality in a camera like this, it should be using an area exposure which would have noticed the blown highlights everywhere else in the shot, and adjusted accordingly. This can be corrected in software, thankfully, but as a user a center weighted exposure means you need to lock on an area of "average" lighting, which, unfortunately, does not play well with an autofocus setup (unless it's fixed focus?). I dunno, just throwing that out there -- pretty hard to say anything definitive based on just one shot in that particular environment.

    Agreed. Would be nice to be able to do a comparison for those that DO value the camera in their smartphones, possibly in the same way that dpreview does for other cameras, with some objectivity. Unfortunately I couldn't, and I was only just beginning to look into it. You are right, I should take more pictures with both and see, but I guess it will still end up attached to a wall, dang it.

    MP aside, since the the thread title is "nexus camera discussion," can anyone comment on the nexus camera in general and in comparison to iphone4, sgsII, rezound, razr, etc? It seems like in many of the reviews I've read, the nexus camera comes out the loser more often than not. Colors look washed out in many sample pics. I wouldn't go so far as to say it's the sensor though, as perhaps the software. But at the end of the day, when I want to take "good" pictures I use my dSLR and when I want to capture a moment and have no other camera with me, then my phone will do. I think the Rezound takes fantastic photos for a camera on a phone.

    This is highly subjective, but I do have a friend who is just getting into dSLR finally, but has become obsessed with camera quality on smartphones since his son was born, because he's always snapping photos of him (he's 5 now). He cares very much about the quality of the camera on the phone and that is actually like his main requirement in a phone, that it be one of the best at snapping photos.

    Anyway, he's a bit of a phone whore and has been through quite a few between him and his wife. Most recently, he's had the incredible and a test drive of the iphone 4s. He liked the camera on the iphone, but disliked pretty much everything else. I was letting him play with my Rezound and showing him sample photos and he immediately fell in love. 3 days later, he had the rezound and feels that it takes very good pics, comparable to the iphone 4s in general, and better in low light. Now the Nexus is out and we are both looking at sample pics and are disappointed. The difference is, he won't get the nexus because of the camera, whereas the camera is less important to me, so I'm still on the fence.

    i agree some more technical reviews would be nice, but there's an anectodal "my friend said" example for you.

    For what its worth, the photos on the Nexus seem inferior to the sgsII, iphone and rezound and in some instances even the razr from the samples i've seen. I'm just not impressed, but it's not a dealbreaker for me.

    I definitely understand that a camera may or may not be important to the user. I remember the days of the Palm phones when they combined the Palm Pilot with a telephone. I remember thinking "now what the heck do you need all that for all the time". Things change!

    Now we can access calendars, email, videos, music, pictures, play games, all on a computer/phone that as my dad says has infinitely more computing power than the entire university he attended had in the late 1960's.

    I used to think I didn't care much about a camera in my phone- just snapshots of stuff, but now that they can be good pictures, why not? So to me it matters. The only thing I might not love about the rezound is the fat profile, not a big deal, and the buttons which are going to be redundant soon with ICS, unless they get written into sense for 4.0. Even then, the disappearing buttons on the GNex are a way cool idea. Progress.

    I take pictures with my phone for selling items on eBay and one thing I was worried about going from my Inc to the GNex was the camera difference. Some of the items I sell, such as baseball and football cards, I need EXTREMELY detailed pictures because the buyers want to make sure on a $350 rookie football card that there is not a blemish on the card and they want to be able to read the writing on it and make sure everything is legit. My plan was to hold on to the Inc until I can get a good dSLR (which is hopefully happening this spring). After taking a round of trial pics with my Nexus, I just put my Inc up for sale because I don't need it anymore. :)

    I haven't taken TOO many pics with mine, but I think the sensor is probably a lot better than early sample shots might suggest. I say this because I think it's capturing better low light photos than about any phone camera I have messed with. Now the issue is that it seems to have some odd issue with it's full auto control and any bright back lighting in a scene. There are a few scene setting and manual White Balance and such that might help with this until there is some sorta update, but I haven't tried them too much so much as I have found any sorta backlighting, even if peripheral back lighting exists to the side of the scene you are shooting it seems to send a glare across the sensor and wash out the picture.

    I'm not really thinking it's the lens or sensor though so much as it's trying to get too much exposure in the presence of back lighting rather than relying on it's LED flash(this one is better than most) which tend to be a bit weak. If nothing else I think just putting exposure control on -1 when you are worried about back lighting will help. It tends to bias torwards overexposure really so just keeping exposure control on -1 might work in general unless you are pretty sure from the preview it's getting it right. Not sure why the colors get messed up if the exposure is a little long, but that does seem to be part of what is going on. I also wouldn't be surprised if the other aspect is that it's jacking up ISO too hap hazardly to get maximum light at the expense of color vibrancy.

    Basically though I am pretty sure some updates to the software will make this an equal to the SGSII and iPhone 4S pretty easy. You have to understand this is a bone stock Google camera implementation without all the effort to get things perfect that I am sure goes into the proprietary camera software and JPG rendering routines on those phones. It really does seem that the full auto nature of things isn't making the best choices A LOT more than an issue with the sensor. Full dark flash photography on this thing I think will beat any camera phone out there from what I have seen. Not sure if the flash is better or if it just gathers light that much better or some combo, but it will pick up thing MUCH deeper into the shadows than I have seen from other camera phones.

    You sir could not be any more wrong. Megapixels do mean something, but to be honest, anything over 5MP is overkill. In fact, the more megapixels you put on the same size image sensor, the worse the quality gets. You start picking up more noise. Megapixels are a marketing gimik and nothing more. Any money spent by a developer/manufacturer to put anything larger than a 5MP sensor in a phone is simply money wasted. That money should be spent on enhancing the optics that are in the camera. A 5MP camera can EASILY produce a QUALITY 24" x 24" print. Now tell me, do you actually plan on taking a picture with your phone and blowing it up to art gallery sized proportions? No. I'd be willing to bet that 95% of the pictures taken with phones never see anything beyond a 1024x1024 resolution image uploaded to Facebook...if that much. That is 1MP. To be honest, anything over 2MP in a phone is overkill, but 5MP is pretty standard for point and shoot now, so that's why they're 5MP. Anything beyond that is simply money wasted.

    Seems we had enough discussion to understand why higher MP doesn't matter much in phone camera. It's lens and software. I like to see some actual pictures taken by owners of shiny new Gnex.

    Also, this guy did a good job showing the camera can be as good or better than something like the iPhone 4S depending on the situation. As he is saying, better than you may have heard. It's probably not QUITE as sharp as the 4S, but I think it's more due to the lens being used than the mp's at work. Doubt any of us have 5mp monitors to view these on. And I think it has better dynamic range than most shooters.

    Does anyone actually try to print small poster-sized copy from camera phone? I'm just happy that I can whip out phone to take clear enough picture at the time of car accident ASAP. 5MP or 8MP really doesn't make a difference in camera phone when just about everything uses 1/2.3" or smaller sensors.
  24. jasaero

    jasaero Well-Known Member

    Yep and that article doesn't even include the 1/3.2" or 1/4" that most Phones use. I have been saying for AWHILE more top teir Smartphones need to worry less about ultimate thickness and put in a 1/2.3" or larger camera sensor. My guess is that you could fit a 1/1.8" sensor in a phone and still have it reasonably thin if you were crafty about the design. It might end up a full half inch thick, but that would be fine with me if I had an extreme grade sensor.

    I really feel though that 5-8mp will be the real limit on 1/3.2" phone sensors and they should be able to create plenty fine pix if they optimize these sensors at that MP and refine the lenses and such. Really would like a slightly thicker phone with a bigger 1/2.3" or 1/1.8" sensor and maybe 8-10mp with really great low light abilities though.

    Yep, and 1/2.3" is RARE in a phone, but they do exist, just not in any top end broadly marketed phones.
