Hi everyone!

Maybe you have already used Lcamera with longer exposure time
https://forum.xda-developers.com/nexus-5x/themes-apps/apk-lcamera-longer-exposure-shooting-t3516152

It allows to make great night photos, but this camera has a fairly limited functionality.
So, i took the source code of fully featured Open Camera and did the same - took away exposure time restrictions.

Keep in mind:
- application is unstable with long exposure time
- preview has max exposure time 1/12 sec
- tested only on Nexus 6P, Android 8.0.0
- I changed only a few lines of code and forced to use camera2 API by default

Stock Normal - Stock HDR+ - Open Camera (5 sec, ISO400)

Works great. Waw. Thank you. Can you share the source code ? Github?
Waw.. Working perfect..
Incredible.
The maximal I get before this mod was 1/12s.
In fact, When I use 5s I get 9s exposure and when I use 1s I get 3 s exposure. It's possible to use with iso 60 to.
Low iso + long exposure in our right noise cam sensor is amazing..

Please, maintain this always updated.. Send to github for future mods...
Can you compile using 30 seconds instead 5 for a test?


Thank you so much

I have already shared it here https://github.com/vbohush/OpenCamera
Thank you for reply!
Yea. My previous post I didn't read it. Thank you.

Can you try to compile using 30 seconds to test? I need to install all the sdk/studio to do it.
If possible.
Maybe you have your environment already setup there to do it.
Please? :)

Obs: I just read your 60 seconds APK. Thanks.

Thank you

Here is build with ability to use up to 60 seconds exposure time
https://drive.google.com/open?id=0B5...1JoTUFzSnpfN0U
I haven't tested it yet, use it at your own risks.
Thank you...
The limit using our non modded kernel seems to be 10.2 seconds.
The open camera time is not linear insde the 5 seconds. Show 5.3 seconds but count 10 seconds. Show 1 second but count 3 seconds. Is working under some exponential sequence.
Curious that the minimal expo change to and same using the auto mode now control the iso aperture better than the non modded one.

Thank you.,.

So I have been using lcamera for low photography. It's true that it doesn't have even the basic of camera controls and options. For that reason, I got very excited when I saw this post. So tried the modded opencamera app on my google pixel xl.
So the lcamera seems to be giving more exposure time when set on 5s than the modded opencamera app set on 5s. I might be wrong so I've attached the images I took. Have a look and please explain and discuss what is happening here. if we can really get a 5s or more exposure on opencamera fully functional, that'll be amazingly awesome.
for example, the stars are more visible in lcamera on iso40 than modded opencamera on iso50, 5s exposure on both.
xdaforum was giving me error 500 when trying to upload the 2nd set of images so i've attached the zip file with all images.

lcamera VS moded open camera

Hello. Problem is maybe not only in exposure time. Time to take 5s exposure is similar on both apps - lcamera and moded open camera on my phone. But I need to double iso setting on moded open camera to have similar brightnes of fotos.
