it looks permission problem. relevant part of stack trace is:
java.lang.securityexception: permission denial: starting intent { act=android.media.action.image_capture cmp=com.sec.android.app.camera/.camera } processrecord{3ef341 9055:com.example.gary.natureall/u0a10} (pid=9055, uid=10010) revoked permission android.permission.camera
you'll have add
<uses-permission android:name="android.permission.camera" /> to manifest, , android 6.0, have handle permission @ runtime - see app crashes due java.lang.securityexception example
