I don't really understand how those wetsuits are supposed to protect the internals. It's not the surface areas that need sealing off, it's the seams. Do they divert water away from the craft in general by being water repellant?
I have been searching and I'm surprised there isn't a Lightroom profile available this device. I am considering making my own with an X-rite Color Checker. That should resolve all of these issues. I'm sure others have already made them, just doesn't seem that they're putting them online.
