mobius121... As can always be expected,
Hatman12 is a source of valuable advice and observation (least I've found that to be true in my reading).
At 100% they must be completely and absolutely free of any noise/artifacting. IS, SS, DT, StockXpert will shoot it down in a heartbeat. It must be absolutely crisp in focus, not close, but dead on. ...if you want to sell them on micros.
On the other hand... and this is what has always confused the crap out of me. When I deal direct with editor and art directors, they couldn't care less about such extremism. In fact, the latest magazine issue hitting the bookstores this week with our work, has a nine page spread written
around our pictures (wife and I) and it is with great belly laughter that I say, 25% or so of those pix were shot down by the micros for
noise. Yet, the magazine looks .... perfect!
go figure.... why, I don't know. Maybe because they aren't making billboards with them?
But on the micros.... it's gotta be outstanding. Incidentally, your work looks fabulous!!
