Thanks for the replies so far
Looking at the solutions so far, as well as doing some of my own research....
A liner/shell situation isn't ideal, I've tired it before simply for warmth purposes but I'm a snowboarder and I've found that I really
use my gloves, for one reason or another my hands are always in the snow so I'd need something waterproof at all times more or less
I will definitely look into tactical and hunting gloves, that's a great idea that never occurred to me
I also came across those free hands gloves, turns out the company Freehands' has a whole line of gloves with convertible index fingers and thumbs for great prices, but it looks to be somewhat of a rinky dink operation
The last thing I found, which seems to be nice, but expensive, is the specialized solution I knew there had to be, are these:
Winter gloves for photographers – The POW Photog » Dan Carr Photography - Photography Product Reviews + Ski, Snowboard and adventure photography tips
They really seem no better than the other solutions though, if only they were a shell
