Michael do you realize that the OP approached the query with one idea, then branched into a side analysis....does salt+1:100 stand yield a nice image?
Had he scientifically quantified the virtues if stand, he'd be no where
Can't we just agree that the artist Thomas cites had nice results (eg Steve Sherman), and thus your whole point that the virtues of stand need to be proven before beginning any suggestion that salt is a new varriable that can have any effect on outcome?
I was reading an article today oddly enough suggesting that those in science need to experiment....
Sometimes the formal (eg six sigma) approach is great, but to find a new N....outside the box
Don't believe me, search "Google X Labs)...
