n9 camera darker than preview / hack for improving it?
 

i've been trying the camera at home and realised that the photo is darker than the preview. If try in the same conditions with my galaxy nexus, and a nokia n97 mini and the photos are brighter. Is there any hack for improving the camera?

Possible screen set on high brightness??
I've noticed if the phone screen brightness were set to the the lowest.
The preview are almost exactly same as the picture taken.
But can't be 100% sure. :D

Check the exposure setting. I had a similar issue when I first started messing around with the camera and I had somehow turned the exposure all the way down.

ok, maybe i didn't explain it well.
i know that with the exposure i can change it, but there is no other option?

i've made a video taking pictures with my n9, galaxy nexus, n97 mini and 5800XM.

If you pause the video in sec 9 you will be able to see what i was asking. it's like the phone is taking the photo a bit before/after the flash, like not getting all the light from the flash. you see the preview bright, and when is stored, is darker. I don't know if i'm making my self clear.

I'll show the video and the different photos. They are with standard iso/saturation/exposure settings, and max quality and resolution

Don't shoot on totally dark room, phones have different kind of flashes. So your question is not about improving the camera, but improving the flash timings in totally dark room.

And shooting on totally dark room is a usecase that is not common and that's why there is no stupid optimisations for that. I would start to worry if pics would look too good in totally dark room, since then pics would look crappy on with normal lighting.

N9 makes best pics outdoor with decent light. And if you need to use flash then your doing it wrong :)

have you seen the video? and the time i mention? my question is about why when a picture is taken the first preview, that which last about 1 sec, is brighter than the actual picture

When I take a picture of a white paper with some text I get the following problem when shooting in "auto white balance" mode:

searching object to take picture from (the white paper): perfect colors on my screen, nice white sheet with blue text.
focusing on object : still perfect colors on my screen.
when taking picture: white sheet becomes dark yellow with black text.

When I select TL-lighting for white balancing, the result is better, it's white, but a little darker then when focusing on the object.

------

It is strange that the colors are perfect on screen before I press that shutter button, but after pressing the shutter button it looks like the phone ignores the white balance option and gets very bad colors.
