    After using N9 for about 1 months,

    I find a very obvious problem of N9 camera module,

    when there is high light in the darkness,

    the glare problem is very clear,

    comparing to iPhone4/4S or Samsung Galaxy S2, or N900,

    It is very clear :



    Do you find the same problem ?

    I think the N900's camera is a little bit sharper than N9's when the light is enough.

    But when the light is lower, the N900 performs much better than N9.

    Even iPhone 4/4S and Samsung Galaxy S2 performs better enough than N9 in low light conditions.

    Do you think so ?

    n9 camera is definitely not the wow factor even though how much it was hyped.

    Agree. Bright light ruins all photos.

    The camera itself (hardware) is fine, it's the camera app's inability to decently measure correct exposure that is the problem.

    Fortunately there are lots of manual options in the menu including the ability to manually set exposure compensation. Use that and you'll get much better night photos.

    @OP

    Most of your claims in your prior "N9's camera is poor compared to N900's" thread didn't smell right.
    And Damien Dining was in agreement (tweeted him)....
    I suspect you're coming from an un-solid (technically) place again...
    But I'll wait for commentary from others who own both, & can weigh-in.

    Fantastic picture! Would you mind sharing what settings you were using for that picture (ISO, white balance, compensation, etc.)? I've been struggling to optimize the N9 for shots like that, and a little help would be useful.

    Thanks!

    This seems to be the settings he may have used...
    Scene: Automatic
    Flash: Off
    White Balance: Automatic
    Exposure Compensation: 0.7 (maybe up to 1.3)
    Color Filter: Vivid
    Light sensitivity: ISO 800
    Aspect Ratio: 16:9
    Resolution: High 7Mpx

    Looking at the Data on the File:
    Scene: Auto
    Flash: Off
    White Balance: Auto
    Exposure Compensation: -1
    Color Filter: Auto
    Light sensitivity: ISO 174 so auto

    That's helpful - appreciate it. Of course, based on my fledgling photography experience, it seems a great deal of how well the exposure turns out is based on where exactly you choose your focus/exposure point. With the N9, it seems that these are one and the same point (which, for general purposes, is somewhat reasonable).

    I left EXIF data intact so it's all there.

    I have found two ways to get better night pictures.

    The first one is to limit max light sensitivity (ISO) to 100 or 200. This eliminates most of the grain/noise, but sometimes leaves you with pictures that are too dark. I think there may be some shutter length limit in play.

    The second one, and IMHO the better one is to set negative exposure compensation which basically tells the camera to make darker pictures.

    Keep the camera in auto-everything by tapping "auto", then disable flash and tap the exposure compensation setting. Slide it to -1. Then aim your phone and take a look, everything should be noticeably darker. If your light source is still overpowering everything, add more negative exposure compensation by moving the slider left (-2 is max). If the scene is to dark, slide it more to the right. Once you're happy with the result, close the menu and take a picture.

    If you're not sure, take multiple pictures, you can later review them and figure out what works and what doesn't.
