Here is a link to a short video I scrambled from the test footage I shot with Panasonic LX15 on my liveaboard trip to Sudan in may.
All is shot with ambient light, no additional lighting, all color corrected and edited in Hitfilm Express.
I was mainly doing photos, as it were literally my first dives with the new rig, hence the quality of the video is mediocre, just to test the capabilities of the camera.
Enjoy
