It's not so much trapping as it is condensing. Like an hourglass shape. you wouldn't be able to touch the hardlight really, now that i think about it, since it would basically be like a lightsaber. but I think that's a pretty good sheild don't you? just incinerate the bullets?

It wouldn't have to be that thick. maybe half an inch at the most. and I'm thinking maybe 2 square feet of surface max.

(I've spent the past hour or so researching light and it's properties.  might look into this farther outside of the RWBY universe.  this stuff is cool.)
