I use the Nik Complete Collection as an Aperture plug-in, and have been very happy with it. I just learned about the Digital Film Tools suite of plug-ins and am thinking about trying some of them. http://www.digitalfilmtools.com/index2.htm Anybody have any experience with DFT? DFT's PowerStroke seems similar to Viveza, but has a unique stroke based interface. Also, how does Nik's Sharpener Pro compare to DFT's reFine for sharpening? Look forward to your input.
