I thought the OP did 4 tests (1+25, 1+25 w salt, 1+100, 1+100 w salt)

See posts #65-75 or so....

Heck Polygot have him kudos for attempting a controlled test

He's not perfect but I thought the OP's design was well thought out, executed

What shd he do to be better?

Regardless if I got the artist wrong who used X dev vs Y, there are examples of artists making great art w stand. So if they can accept a steak or two 3 out of 10 roll (what Thomas mentions) that is their deal....

I have done stand a few times and not liked it, but I can't deny a photo that looks great having used it...
