Water droplets on the lens
Also known as: water spots on lens, lens droplets, water on GoPro lens
Drops of water that cling to an action camera lens cover and show up as blurry blobs, a common problem when rafting, surfing or riding in rain.

What it means
When a camera comes out of the water or catches a splash, drops stay on the curved lens cover. Because they sit right on the glass, far closer than anything the lens can focus on, they appear as soft blobs or smears that distort part of the frame, sometimes for the rest of the clip.
On rafting, kayaking, surfing and wakeboarding trips this is the most common reason a great moment ends up unusable. The wide field of view of action cameras makes it worse: a single drop near the edge can cover a big part of the scene, and a low sun turns it into a bright flare.
How it works in practice
The two main fixes are coating and handling. Water-repellent glass treatments or dedicated lens sprays make water bead up and roll off; reapply them every few sessions. Surfers famously lick the lens cover before a set - a thin film helps water sheet off evenly instead of forming drops.
Mounting matters too. On a raft, a camera on a helmet or on the frame facing back catches fewer direct hits than one on the bow. Dunk the camera fully just before a big rapid or wave, since an evenly wet lens often clears better than a half-splashed one. Split shots through a dive housing dome port get the same drops and need the same care.
What to watch out for
Wiping the lens with a wet glove or a sandy sleeve leaves streaks and scratches that are worse than the drops. Carry a microfiber cloth in a dry pocket or a sealed bag, and do not overdo the coating: a thick, poorly buffed layer makes everything look hazy.
Do not count on fixing it later - no editor can bring back detail hidden behind a drop. Also, check what you are actually seeing: haze that does not wipe off is usually fog inside the housing, which needs a different fix. Wipe the outside first, and if the blur stays, the moisture is inside.
How RawClip handles it
RawClip does not repair droplet-covered shots, so a clean lens has to happen on the water. Upload the whole session and the AI picks the strongest moments by motion and peak action for your highlight; clips that are badly smeared from start to finish are simply worth leaving out.
