Someone was asking today if the Nik package was worth the money. Its expensive but I have found it to be very good and worth it to me. I like to to experiement in PP so YMMV but it does many useful things. the following are examples of one picture.
1. SOOC ( some exposure adjustment in RAW)
2. Viveza (localized adustments via control points)
3. Color Efex Pro3 (Monday morning filter on top of previous edit #2)
All of this took me no more that 15 minutes to do. I think the results are good. I encourage trailing the package for 15 days. All the features work. The videos on the Nik website are informative and the webinars are free.
Check it out.
