Go to application->Manage->All->Camera->Clear Default
If there is no default in the Camera try to find the Third Party Camera Apps then Clear Default
Update:
I missed you, I thought you want to revert back from default

This is how
This requires a rooted phone.
1. Download any root enabled file manager. (e.g. root explorer)
2. Go to system-apps and then delete the default camera app.
3. Take the ucam.apk and place it in system-app.
4. Hold down the ucam.apk which should now be in system-app.
5. Choose permissions and tick:
owner- read write
group- read
others- read
(make sure that the others are not ticked)
6. Press OK
7. Install ucam.apk present in system-app by tapping on it and clicking install.
8. Reboot you phone and enjoy
Plz thank me if this helped.
