I've been playing around with the Nik demo. It does work nicely on trains... [attachment deleted by admin]
very nice, scott. so far i have been unable to get nik silver to play nice with CS4, but i still have older versions on my system so i can go back to them.
All the Nik demos work fine with CS4 on my machine. I don't know if I would use them enough to justify their cost, though. :-\
sharpener pro and dfine and tops on my plugin list. silver efx and the others are ok, but the first 2 i mentioned are indespensible.
