I wonder if you develop an ML model that uses brightness and color reduction cues in the video in order to estimate depth in lieu of a dive computer. I suspect cameras auto-exposure or underwater modes may nullify this.

That’s a super interesting idea!

But yea, one big issue is that it would limit how you shoot the video as well. If the camera accidentally catches the sun or a bright surface reflection, the exposure shift could throw off the depth estimation. Maybe locking exposure/white balance settings could help, but it would still be tricky. Definitely an interesting problem to tackle! Thanks for sharing! :)
