Hi,
Almost every camera in the world has a halfway-click that focuses, measures the light and then takes the picture when you press the shutter button all the way.
On other phones (iPhone), where there isn't a halfway -setting, this is done by taking the picture when the user releases the button, which gives much greater control over exactly when the picture is taken.
Do you know of any program (camerazoom, snapshotpro etc?) that works this way? The stock camera app doesn't and it's quite detrimental to the quality of pictures you can take.
This means the camera needs to auto focus when I press the trackball button down and then take the picture within a split second when I let go of the button, since it no longer needs to measure light or focus. I would really love this feature.
Hi ,
Go to my thread http://forum.xda-developers.com/showthread.php?t=551904 the program I mentioned has this option also .
Thanks! Will check it out!
There is a workaround that i use that is effective on my mT3G. I turn auto focus off. That makes the camera focus at infinity. With these tiny lenses, infinity can start at less than three feet. So anything farther away than that is in focus if you turn off auto focus. I use SnapPhoto Pro to turn off the autofocus.
If you use SnapPhoto Pro autofocus, you touch the screen to focus and let go to take the photo. That works well. It also has a continuous focus feature which works very well but drains the battery.
Hi,
I have an odd problem. Running CM10.2 stable.
If I try to take a photo of a subject with bright background (ie: sky in the top half of the photo), even if I focus on the subject, the subject will be very dark and the sky will have a correct exposure. If I put the subject in front of a building, it's fine.
On my Nexus 4, if I focus on the subject, it will adjust the compensation to have the subject properly illuminated (and sky will be almost white), but if I focus on the sky, then it will have the correct exposure for the sky and subject will be dark.
Any idea what's causing this?
Thanks.
This seems to happen on stock factory ROM as well.
Could someone please do a test to see if it's isolated on this phone or if it's a bug in the driver/hardware?
A light bulb is enough to be in the picture, if you focus on the bulb, the rest of the photo should be black and the light bulb clearly seen.
If you focus on the wall, the wall should now be visible and the area surrounding the lightbulb should be almost white (over exposed).
Thank you.
Hi
When i took photos in very Dark place on Pro mode with Below settings there is some white Dots(Spots) on picture(maybe Like Hot pixel):
1- set exposure on 10 (sec)
2- set iso on 800
The spots place is fixed on all photos in this condition...
Is that nature?!
-The Attached pictures is zoomed in.
You probably already have done it, but, are sure your lenses are perfectly clean, I mean, cleaned with a good clening liquid and a proper cleaning cloth?

If lenses are clean, and it really is a pitch black place, and you had the flash off, and the dots stay in same place on every photo, then it has to be
1) micro scratches (from sand / grit)
2) Dust. They could be dust settling on your freshly cleaned lens (static) - I know if I clean my lenses with kitchen roll, it becomes a dust-fest
3) Fault in CMOS sensor. Though I wouldnt have thought the fault would be white dots, as white is after all ALL colours in the visible spectrum, maybe should be red or magenta maybe, but not white. There are different light sensors for each colour If my limited understanding is anything like correct, therefore, for white to be displayed, red/green/blue sensors at that very same point would ALL have to be faulty. Therefore, to me, a CMOS sensor fault seems unlikely.
4) Dust seal compromised. Unless you have had back off it, this shouldnt be so. Return under warranty if knox is intact.
Good luck.

Are you have Note 8?
I tested two other Note 8s and there was same problem too.
My phone is new and there is no any dust or scratch...
The lense is clean and white dots place is fixed in any photos.
Just test it with take picture in Pro mode with 10 exposure and iso 800 in very dark places without any light. Probable you can see this white dots when zoom in the photo too.

Yes, lens is clean.
I tested two other Note 8s and same problem exist.
Please just set the setting like image below and test it:

OK I'll bite. As much as I didn't want to I checked mine. I do have spots but they are only in the lower left (lower right on these pics because of the rotation) and vary from dots to lines. I suspect it's a limitation of the aperture seeing it only happens with a 10 second exposure and 10 is it's set limit. The first pic was in a dark closet and the second is with a thick cloth over the lens. It's not a deal breaker in my case because I rarely if ever would set the exposure to 10 seconds, I'm mainly a point and shoot person.

I think you didn't set the ISO to 800 in these attached pictures, yes?!

I did. Iso at 800 and exposure at 10 sec. Any other exposure other than 10 seconds and the spots are gone for me.
I took this picture in iso 800 and exposure 10, you can see the white spots clearly:

Yup, it looks like stars. Hopefully others will check as well.
My Sony dashcam does the same thing.

I tested the cam at 10 sec exposure and ISO 800, and yes, there are star like spots, but only visible when enlarging the picture, I had seen this happening with othe phones and cameras at no extreme seetings, that is, not entire seconds of exposure, no totally black pitch ambient, In fact I think that this happening only at 10 sec of exposure is not a big deal, when these dots appear, it is in a situation that almost nothing will be captured in the photo, if something appers in the photo, means there is enough light to be registered, and then, you would not notice the dots, as I most surely will not take pictures in these conditions, I am not worried, I take standard photos all the time
It's normal
Okay. Just tested mine. Same thing. However I do have to mention that I frequently take nighttime photos for astrophotography and typically you wouldn't want such a high ISO on a long exposure because it introduces noise to the photo. And 800 is the highest ISO setting that the Note 8 has. Any camera will do this to you. The long exposure will collect enough light by itself to negate the need for such a high ISO. Not really a defect in the camera, just the process of taking the picture.
Recently bought the phone off Amazon and started messing with the cameras and noticed i could have my fingers over the top and bottom camera on all modes and zoom one each and it never used them? Did I get a faulty phone or am I using something wrong?

I heard this and think it is true for the P9 too, but I've learned some things since then. There are a lot of modes and resolution combinations. Try the basics first. Top cam is only zoom. Bottom is B&W.
For example, I cannot shoot with finger over zoom lens after choosing 3x zoom in Photo mode and waiting for the zoom lens to kick in (the image stabilises once the zoom lens is active).
I would try with and without AI, with different resolutions and with different modes. I just tried night mode on 10mp and covered the B&W sensor, so maybe it's all a big scam.
Thought the same first but now im sure all of them are working fine .
The phone can only use two cameras at once anyway to my knowledge .
When you zoom in good lighting it will switch to telephoto cam ( top cam ).
When you shoot in bw it will use monochrome .
When the phone tells you to stabilize fot sharpening it will trigger the monochrome sensor too .
Hi,
anybody having this issue as well?
The 5x zoom is useless for me as the camera is unable to get in focus. So a few milliseconds and only occasionally it gets sharp but then it looks blurred again.
10x produces sharp images.

Thanks!
You have to keep in mind it is a lot slower to lock focus than the main sensor. Give it time to lock on target and then take the shot or else you will end up with unfocused shots.

Well it locks but then loses focus.

I assume this is not normal, I have asked for a replacement.
I have noticed this issue when trying to take a photo through a window. No matter how close you hold it to the window, it will try to focus on the window. Then if you wait long enough (5-30sec) it will focus out to infinity but then it will pop back to the window after a few seconds.
It should really default to infinity since that most objects you will use the 5X lens for will be far out.
Sometimes when it just isnt working, I switch to Pro mode and manual focus, but the interface is clunky and you lose some of the auto-features.
I've never had this issue before with other phones when taking photos through a window.
I also noticed that it is not as sharp, but I assume that is a limitation of the lower resolution sensor and maybe the OIS not fully compensating.

Mine focus perfectly through windows.
