Brutal. That’s dildos. Worse than a scuba tank full of farts.

Still waiting for the other single from the album- Scuba Tank Full Of Farts

Not sure that I'd call it trivial, but from what one can gather, using the panel of known colors as a calibrant for correction during processing does seem like an obvious approach. I'm assuming that the newsworthiness of this is in the trick or complexity of the post-processing - removing scatter, haze, correcting the full color spectrum with multiple calibration points - it won't be a simple linear correction. I ain't no expert, but have spent oodles of time trying to color correct videos and stills from our scuba trips, and the *automatic* color correction in current software is still pretty poor IMO, relying often on a single color as the calibrant (so, a "pure" white region in the photo, a "pure" black region in the photo etc.). Manual adjustment of the photo color balance for UW vids and photos is on my list of "What Hell must be like".

I have huge respect for the fitness and ability of these guys.

But I think they're completely insane.

I'll stick to scuba....

Lower water pressure would inflate the swim bladder, increasing the buoyancy. Higher pressure makes the bladder easier to empty, making it easier to sink.
You get this effect when scuba diving - it is harder to get down from the surface than to get deeper when you're already several feet below.

Because nicotine itself is not terribly addictive. The main components of addiction to tobacco are now believed to be other substances.

Now consider the mechanical act of smoking; inhale, exhale cloud, reward.
Using a vaporizer reproduces the physical act that smoker's brains associate with the reward.

There does seem to be a period at the beginning of using a vaporizer, where there's a craving for cigarettes, perhaps because of the other addictive chemicals that are absent. But this craving isn't particularly difficult to overcome when you're satisfying the other elements of your habit. Not to mention, lungs clearing, sense of taste returning...

Then there's the final stage of using a vaporizer, which I've seen happen with others and I've experienced...you lower the nicotine levels further and further and then one day you start forgetting to use it at all. Your frequency of use may drop to nothing. Not always though. Some people go truely insane. We call them "scuba vapers". One of my buddies has earned the nickname "Darth Vaper".
