Hi,
I have searched from all over the web app that could change camera's exposure time. I like to take good nigh photos, or anyway as good as it's possible with mobilephone camera, but like in mine HTC Desire exposure time is way too short.
I have tried many of those camera apps from market, like camera 360, but non of them can adjust shutter speed/exposure way I wanted. Say, I want a long exposure for night photo. For example I would like input exposure value to app, so that it would expose photo for 10 seconds.
So, do anyone know app to change exposure/shutter speed?
And my Desire is not rooted and I'm currently not planning to do so.
Would love to know about this, too; any ideas for this?
Sign me up for this as well.
Long exposures would be great. Would need some sort of remote shutter release or time delay ideally and a mounting system, tripod fashion.
Problem is - you'd also need a mount or tripod of some sort to hold the camera still enought to make long exposures work
I don't know about the rest of you but I can only handhold steady my DSLR down to about 1/80th of a second

I have managed 1/15 and 1/8 (the latter very rarely) handheld with my Pentax (image stabilisation built into body FTW), but yeah, you would have to use a tripod or to prop it up and have a timed shutter release for the phone. This isn't a problem as such, even just being able to specify the aperture would be welcome.
Well a mount can be anything...jumper, phone leaned against a wall. Would be awesome for cityscapes and such. Anyone found anything which indicates this is possible with a software patch? New to android and just tearing through my first rom package
Exactly, it doesn't have to be anything serious, just lean it against a beer for example.
I can't see a reason why you couldn't manually control everything, I can control ISO, metering, etc on my SGS, adding aperture and shutter shouldn't be outside the realm of possibility.
Had a look around as a noob to Android dev/roms etc. and I don't think it's possible to control the hardware to that level :/
Would love to be corrected on this, though!
I don't have the SDK installed anymore, can someone test what camera.getParameters gives on a device?
This would be great, the DX has a nice camera but additional lens control would put the icing on the cake

I can handhold my Leica down to 1/15. You need more practice (a lot of it).

Not to be too big a jerk here, but if you can only hand-hold an SLR steady, any SLR, at 1/80 or faster then I'm sorry to say that you may have a serious case of parkinson's, or are the most ADHD person who ever picked up a camera.
1/60 is recognized as the speed at which regular hand-held motion is mitigated, and unless you're actively moving the camera (or standing on top of a paint-mixer), you will not get camera-shake at that speed. Most photographers are able to hand-hold, and get a shake-free shot, down to about 1/8 on a good day.

What was the rest of the code? and did you try this on actual hardware or the emulator?
I will try to code an app for that. Plus FFC Support...
but you'll have to wait until I'm back from Japan
EDIT: It's not possible to really influence the shutter-speed or the aperture, because it is non-existent in the hardware, but there can be an interpolation of both values that are calculated from ISO settings and exposure calculation. It won't be perfect in any way, but it might be possible to do something similar... probably it is possible to gain more control via the ndk or by "cheating".
Thanks Flokey!
Does anyone knows if there is such a program?
I don't think a long shutter on todays camera phones would be useful as the sensor noise would be crazy bad.

I don't think they should be in the same thread because they are different issues. Perhaps they are related, but then it would be do to a hardware issue.
What's the preferred means of posting examples?
If your having problems with both stills and videos, then it is likely related. You can attach jpg files to your post. You can upload vids to YouTube and post the links here.
Here are a few example shots.
The 1st shot is with the camera settings at default. The 2nd shot has anti-shake on. The 3rd shot has auto-contrast enabled.
As you can see they are all grainy and blurry even though I'm taking an image of something that is not moving.
The light produced from an overhead halogen. However, the pictures turn out similar under standard incandescent, fluorescent, or any other non-natural lighting. Also I tried out several other settings without any improvement (e.g. setting white balance to incandescent, setting the scene to party indoor, using macro focus instead of auto, etc.).
That's sensor grain. It happens when there is insufficient light as the sensor has to work harder to expose the scene and it heats up. Also, since the scene is so dim the camera is using a slower shutter speed, which results in some camera shake that causes a less sharp photo. Can you take a pic with the flash on? Also, if you are expecting Canon-level photography from this (or any cell phone camera) expect to be disappointed more often than not.

Cool, thanks so far. I will try it with the flash on. I have taken pictures in a lot of indoor light and if anything is moving the whole image is blurry. Sometimes it looks like the air is shimmering.
Perhaps what I need to do is to use something other than auto ISO?

Nope, just like Miami_Son said, auto flash will make the difference. That or bright enough lighting. Try it during the day time.

Like I said, in low light the camera will pick a slower shutter speed, which causes camera shake and blur of anything moving. What seems well lit to the eye is different for a camera sensor. Either use flash or turn on more lights. You can try turning up the ISO, but that can also increase grain.
Record video in 720p and the autofocus issues should go away.
So why don't HDR apps work properly on our phones?
One manufacturer I contacted insisted that it was because the EVO 3D doesn't utilize the android api properly to adjust the exposure setting. I even confirmed this with HTC. You can try it out as follows: If you open the camera app and play with the exposure slider in the options, you'll see that instead of changing exposure, what it does is just bumps up the brightness of the image.
HOWEVER, yesterday I noticed that the exposure does change properly but not when you use the slider. Best way to try this is sitting next to a window on a sunny day. If you point the camera towards the window, the exposure auto adjusts you can see the details outside but anything inside the room still in the frame just looks dark. However, if you point the camera so it's mostly pointing inside the room, you'll notice that the exposure auto-adjusts again so you can now see details of objects inside the room but any part of the window still in the frame is now completely washed out. So..auto-adjustment of exposure works.
Now in most of the these HDR apps work by taking a picture on high, medium, and low exposure and then stitches them all together. However, the app isn't able to adjust the exposure settings properly and this is probably because it's tapping into the "exposure setting" in the camera's api...the same thing we are able to change when using the exposure slider on the camera app. As I said before though, the exposure slider is actually controlling the brightness. But I'm now certain that the camera is actually able to adjust the exposure but only does so through auto-adjustment. What's broken is the ability to set the exposure manually. How would one fix this?
where should i post this to get the attention of the devs who might know how to fix this?
The issue is it is a hard question. lol I don't have any idea. haha. I think the issue is we have two front cameras.

Interesting... I've used a couple of hdr apps on gingerbread and they appeared to work. Although I didn't do rigorous testing. All I did was compare normal pic against hdr app and I noticed a difference. However this was last summer. Maybe something changed since then.
Sent from my PG86100 using XDA
Oh and the stock camera app in ICS, or at least in the couple of roms I've tried, has hdr as a feature. Except it isn't true hdr I don't think. It snaps 1 pic then processes it. I didn't think there was any difference at first, but I did notice a slight improvement.
Sent from my PG86100 using XDA
There will always be slight differences between stock vs HDR pics because the HDR app usually does some post-processing however, if it's not taking 2 or more pictures that have the exposure adjusting drastically, you're not really getting the HDR effect.
Yes, I know about hdr... The processing and everything. I just hadn't tested these things like you have and sharing my experience.
Anyhow... I had also read others claim htc didn't use the app right months ago. Not sure why they messed that up. I'm going away for the weekend and might mess with this myself. If I see anything worth adding I will.

That's excellent news! Are you sure the exposure setting works properly and doesn't just change brightness? I know you probably tested it before posting but if you could do this for me and write back, i'd really appreciate it.
From inside a room from a distance, point camera towards a window. Are you able to see detail inside and outside the room by changing the exposure slider to either extreme?

I haven't had a lot of time to play but it did work. I'm a photographer and video producer so I know what to look for. My quick test however was as a passenger in a car. I pointed it to the seat where part was in bright sun and then other was in shade, plus some of the frame of the car in shade. Stepping down showed the detail in the seat in sun, increasing it showed it in the shadows.
I also tried hdr + (I think that's the right one) and each of the 3 photos was at a different exposure, granted not by much.
There is still a bug where the front camera flips the photo left/right after it's taken, however, you only seems this after reviewing the pic.
Edit: the app was hdr camera

awesome, perhaps HTC got around to fixing it in ICS. Several months ago, I actually contacted them describing to them what was wrong with the camera. After a lot of back and forth and escalating the issue internally, I was finally able to reach the team that actually works on the stuff and they confirmed the issue and said they will include a fix "in a future release" but did not make any promises. Maybe they got around to it
I'm going to have to flash a ICS rom to test this myself once I find some spare time
I've had the phone for a couple of days now ant the battery life is stellar but the camera is such a disappointment. Compared with the S22 Ultra it lets in less light and the pictures are overall darker. Same goes for low light pictures, the S22 Ultra is consistently brighter in all scenarios. It reminds me of the difference between my iPhone 13Pro and my S22 Ultra last year the former always capturing more light. To be honest I was expecting the opposite to be true with all the reviewers clamoring about the S23 Ultra's better low life performance and camera overall. I'm really not impressed so far.
Anyone else still in possession of both phones? What's your experience been like? Any suggestions? Did I miss something in the setting? So many questions
Clear cam data, try a hard reboot and clear system cache. Try in safe mode.
Carefully go through -all- the cam settings and options.
Return it if you don't like it for a cash refund.
Are you using the 12 MP default option instead of 200 MP? The 12 MP is said to give the best results on colors and contrast when shooting in low light.
"Binning pixels like this increases their effective size, allowing them to gather more light and detail. So the ISOCELL HP2 can bin every four pixels to effectively make them 1.2μm in size and produce 50-megapixel images, or bin 16 for even larger 2.4μm pixels and 12.5-megapixel images."

Done. No dice. The camera still lets in less light on the S23U. In the settings I noticed that Camera assistant is missing. Must be a One UI 5.1 thing. Do you also have the S22 and S23 Ultra? Is that the reason for your suggestions? Are you seeing different results?
I'm upgrading from S22U (SnapDragon) to S23U and the few comparison shots I've taken I found that the S23U does capture slightly more detail, but there's not much difference at all. Remember this is the initial firmware for the phone though so the camera performance should hopefully receive some updates over time.

For sure. I totally get that. The thing is all the reviewers said that the s23u captured more light and that has yet to materialize for me. They were using the same software. To your point, the software should get better but I feel as though this is a hardware thing. But I'm no expert.

Try shooting raws, at least 3 f/stops more exposure and WB correction. Downside is the post processing effort/time required.
The issue may simply be the firmware instruction set. Samsung is notorious for dialing things in after the release. I'm still happily running N10+'s on Pie and Q. I demand a dual drive capable device. I'm not pleased at all by the newer Android versions from Gookill either.
The dead zone between pixels on such a small sensor with such a huge pixel count is concerning as is the individual pixel microlense quality. Even 20mp is pushing it. Canon full frame sensors are maxed out at about 26mp.
Regardless of the camera learning it's capabilities, limitations and shooting effectively within those boundaries is what grabs keepers.
I haven't had issues so far with the camera outputting dark images. I've tried some shots inside at night (with main cam), shots outside, shots with main 12, 50 and 200mp modes, 3x, 10x. So far I'm pretty satisfied and also noticed a huge improvement in processing especially for 3x and 10x outside which, on my s21 ultra, I was always doing those shots with gcam. Now I could actually consider using stock, though I need to test way more extensively to know for sure.
Might help if you provide us with some pictures of the issue you're having, maybe side by side with your s22 if you still have it.

I loathe tripods. Learned to improvise and shoot in low light with my Canon Pro cam 15 years ago.
I'll use anything at any height or angle I can reach as a brace; with practice you can land one of a kind keepers no tripod can grab.
Smart phones are poor shooting platforms; light weight so there's little stabilizing inertia and lousy handholds. Poor shutter release and controls. However they lend themselves to bracing well enough. In a case you don't have to worry much about what you brace it on...
The traditional elbows in, wide staggered foot stance, hold your breath works too. Shooting technique counts...

Poor example; different shooting heights skews the results. The AF lock on point is also different so the bottle's print is out of focus in the one shot. Light metering and colors look near identical in both.

That might work for Photos but not very well for videos especially when you are zooming in 20x. Here's is an example where I have S22U on a tripod and zoom in on a waterfall from across the canyon and pan up and down. No way you gonna do it that smoothly holding it in your hands even braced. So for videos I love the tripod. It's the very lightest one they make and perfect for cell phones or light cameras. Change YouTube resolution to 1080p for best viewing.

Not sure how to disable this, as stock camera's autofocus is depending on this sensor. Google camera is not using this, but it's half broken, so I suggest to wait for devs to make a proper config, but I advice you not to bother, as this flickering is rgb sensor highlighting the environment while measuring the depth and it's only for half a second
to establish a proper focus.
As for long time to take a photo, I assume you are using basic mode and device may decide to either use a slow shutter speed or/and hdr based on the light conditions, hence the long time to make a shot.
Experiment with manual modes, phone is capable to take 20 photos per second.
Switch to S mode for example and put a high shutter speed, it will adjust the iso for you automatically if full manual mode is too much for you. This phone is like driving a manual car, no fancy AI to do the job for you like they have on Samsung. Might be challenging at first, but once you figure it out , you gonna make amazing photos.
If this is not related to settings, clear photo app's data and reboot the phone. I had this issue after experimenting with google camera, stock app was not saving photo at all.
