Since the SGSII has a pretty good camera I was wondering if it is possible to manually lock exposure, shutter and ISO settings?
With a full HD resolution I would like to get some nice filming done but without the camera automatically adjusting settings. It ruins the look.
Maybe there is already software out there which I havent found?
Cheers!

The main thing is seems that you'll want to do is to manually adjust the white balance rather than keeping that on Auto.
Exposure lock: There's no exposure lock. However, you can manually adjust the exposure value. So if you want to shoot something bright, you can lower it. If you want to shoot something dark, you can increase it.
Shutter speed. There's no way to manually adjust the shutter speed. (So you can't capture something like a waterfall with slow shutter speed to get the motion effect.) Like most non-DSLR cams, the shutter speed is automatically adjusted depending on lighting conditions, flash, and ISO.
ISO. Yes, ISO can be manually adjusted.
The cam is great and can probably replace most people's dedicated point&shoot cams. But it's definitely not as versatile as even a budget DSLR cam.
The camera changes exposure wile you are shooting. That my problem is.
When I walk out of my flat with my camera switched on I don't want to see the automatic exposure correction. Dunno how to describe but have you never seen the effect when you pan from a window to your wall? It must be possible to lock these settings to eliminate the automatic correction.
What I like to see as an option is the autofocus, I got lot's of refocussing in low light conditions when focus was actually perfect
Also would be really awesome if you could set the exposure time to image starry nights, I mean, the device is called Galaxy is it not
Unfortuanely I am not a developer so I cannot contribute to these options and can only hope some cool devguy with the knowhow has the same wishes as me
Hi,
I try to access the front camera of this phone.
From the debug information, I get that "preview-frame-rates" of the front camera is only 15.
Therefore, when I record a video with this front camera, the maximum fps I can achieve is 15.
However, when I use the default Camera app from the phone and try to record a video from the front camera, I can get around 25 fps. Not sure how this app can do this. Any comments are welcome.
Another interesting thing is: by using the Camera app from the phone, there are two modes with front camera, one for video saving and one for image saving.
It is very obvious that the live preview in video saving mode is much faster (around 25fps) than the live preview in image saving mode (around 15fps judged by eyes), but it is also darker. I guess they use different settings for exposure control for these two.
Is there anyway we can get achieve a higher preview-frame-rate of the front camera ideally through android sdk???
Any insights are welcome.
Thanks.
George
Anyone notice that one the T-Mobile Edge, that when you set "Video Stabilization" to "On" it actually doesnt stabilize the video?
Only when you set it to "off," it'll stabilized the video recording?
It's kind of the opposite, not sure why no one else noticed.
Could be wrong here, but I believe that while recording you not going to notice any stabilization. It's happening but you won't see it until replaying the processed video after the recording is done.

To check video and photo stabilization, try zooming in to 3x, point it at something and try to do a recording with it On and off, the video will do the opposite.
It work none the less, but it's counter intuitive to have it day off when it's actually on.
OP seems to be spot on. Same problem with my regular S6. Video stabilization = off turns stabilization on. With it = on, videos are jittery as hell where even my pulse through my fingertips causes the camera to shake.
So guess there's a bug in the camera app.
I just noticed the same thing with my unbranded regular Galaxy S6. If you have video stabilization turned on in camera app settings it is in fact turned off. I was surprised how poorly it stabilizes the video, so I had to use 'Stabilize' option in YouTube. Then I thought maybe my optical image stabilization component is damaged so I started playing with it and once I turned it off my video stabilization started to work very well. So it seems to be a bug in camera software. Anyway - if you want to have video stabilization you need to have it turned off Samsung logic
The reasoning is because the video stabilization setting in the camera app turns on DIGITAL Image Stabilizing by Samsung via software which is really just counterproductive to the Optical Image Stabilization already built into the camera.
So yeah, trust the OIS hardware because typically hardware > software in this field.

Just a question so OIS is default by default and always on am I right? Even on UHD recording?
More evidence that the switch in the camera options refers to DIGITAL image stabilization:
Set video resolution to FHD (not the 60fps option). Otherwise, the Video Stabilization setting is not available (grayed out).
Set the Video Stabilization setting to "ON".
Go back to the camera, zoom in fully (8x). While pointing at something easily identifiable, without shooting video, note that the image is stabilized quite well -- you can simulate "shaky hands" and the image is very stable, not jittery. However, you are not shooting video yet, so settings specific to video are not activated. What's happening here is the OIS is working, and doing a very good job.
Now, click the video recording button. You will notice two changes in the image: It will zoom in a little bit more without any zooming input from you, and the image will get rather UNSTABLE.
It turns out, what you had selected in the settings is actually, truly, being invoked. No, this is not a bug. The switch is not acting the opposite of how its labeled, even though the RESULT is exactly that in practice.
Here's what's happening: As someone else noted, that switch controls digital image stabilization. This is a software process, that basically crops off a small margin all the way around the picture and reserves these pixels for calculating a smaller moving "window" in the larger captured image space. The software tries to move this window around so that it follows the random small movements from jiggling, unsteady hands, etc. In this way, the image appears stable rather than moving around in the capture space.
This is why, when DIS is turned on, the displayed image zooms a little bit -- that's the "reserve image edges" being cropped off and the remaining image being expanded into the display area.
So, here's what I think is happening: When you have Video Stabilization on, the phone turns off OIS and enables the DIS algorithm. The OIS camera hardware is something like a Googolplex times better as IS than Samsung's crappy algorithm, so the end result is the appearance of IS being turned OFF and a little loss of resolution of the video image as well.
Once the video is stopped, after a few seconds you'll see the DIS turned off, OIS turned back on, and the image will zoom out a tiny bit and become very stable again.
Bottom line: The Video Stabilization setting in the S6 camera app is worse than useless. It's adverse. It should be left off at all times under all conditions.
How did this happen? My guess is, the engineering team responsible for the hardware was organizationally distant enough from the camera software team (keep in mind the latter are trying to develop an app that can run across many phones). The hardware guys put this incredible camera in the phone with awesome OIS. The software guys, not focused only on the S6, passed through the DIS that's been in the camera app forever, and no one engineer was responsible for integrating all this stuff for the camera feature itself, testing it, making sense of it, blah blah blah.
And here we are.
Bottom line: Because of the OIS in the S6, the DIS feature in the camera app is unnecessary and should be left OFF. In fact, the way it works misleads the user into thinking IS can't be had with the video resolutions higher than non-60fps FHD. In fact, exceptional IS is available at all times in all resolutions for stills and video -- the hardware OIS is always on the job, unless you turn it off by turning on the [digital] Video Stabilization option in the settings.
The only bug here, if any, is that this setting seems to turn off OIS, when it doesn't need to. Perhaps with OIS on, and the DIS processing applied to that stabilized image, we might get something even better than OIS alone. Alas...
I do a lot of fishing and I often have to prop up my phone on something random for a pic of my fish while I'm holding it, and I can't necessarily get behind the camera to focus and snap, and then get in front of the camera with a fish in the other hand. All my other, lesser phones would automatically focus when I just pressed shutter, set the phone down and I got in front of the camera. Everything I do now this phone the camera blurs me in the picture, I guess because it wants me to focus before I set the camera down? There surely has to be a setting to adjust this? Anyone know what I'm talking about?
Anyone know what I'm asking? Try it yourself,put timer on camera, press shutter and THEN put your phone down and get in front for the picture. it will be blurry...never had a phone that didn't know how to focus after you set it down. Seems like the camera is focusing on the object when you presss shutter and not the object in the lense at the time the shutter actually goes off...
i found the problem. you have to go to pro settings and on the AF (automatic focus) option, you have to select AF-S, as default in non-pro is AF-C.
basically af-c is trying to take a picture of a moving object, and af-s will focus on the stationary object. so if you are trying to get a still of you and some people and have to press shutting before you set the phone down (and don't want to just take a selfie), go to pro settings and change AF to AF-S and that should work near 100% of the time.
The Pixel 6 only gets 2x digital zoom with it's main sensor whereas the Pixel 6 Pro will zoom until 4x or even 8x digital zoom before switching to the telephoto sensor. Is there any way to bring more digital zoom to the regular 6?
The P6P zooms 0.67x to 20x on the side with 3 sensors, 0.85x to 10x on the screen side.
While I'm not running the google image (google free AOSP here), I recall the camera application had some buttons to quickly switch between resolutions. 0.7x to the wide lens (middle position), 1.0x and 2.0x to the main lens (side opposite flash), 4.0x to the telephoto lens.
I don't remember this exactly, but people are saying that the screen side camera has quick zoom buttons showing 0.7x and 1.0x, even though it is 0.85x per the HAL (on the P6P), therefore it looks like Google is mucking with the values being presented to the users. Probably because they think it looks better to have the wide ratio match and a whole number for the sensor switch.
In reality, it switches to the telephoto lens at 4.3x. BUT, it can ride the main sensor all the way to 20x if the proximity sensor reading is "near"-ish.
It picks the sensor based on a combination of proximity and zoom level, and maybe even other factors that are not yet apparent.
Anyway, the quick buttons shouldn't be thought of as the ONLY zoom levels that are reachable. As far as I understand it, even the P6 (non-P) should be able to get the high digital zoom levels. I'd suggest you try to use the pinch gesture to zoom out and see how far it lets you go.
