Taken with my Galaxy S4 running CM11. I used the Google Camera app with no filters.
There were dark clouds overhead, while the sun was setting in the distance, creating this brightly lit tree in an otherwise dark area.
I just did this. It worked just fine. It's the same file for the camera shutter and the screenshot sound.
/system/media/audio/ui/camera_click.ogg
I just appended .bak to it, and the camera shutter and screenshot sounds are gone.
