Originally posted by jawats Are there other filter / edit collections that are worthwhile looking into?
I'd be surprised if there were another collection as comprehensive as those in Nik. The different programs in the Nik Collection (Color Efex, Silver Efex, Analog Efex, Viveza, HDR Efex, etc) work in different ways. (I have barely scratched the surface with them.) Color Efex uses "filters", which are really individual processing tools. A number of the others work more like other editing programs. Even with your full versions of LR and PS, Nik offers ways of doing things that won't be readily achievable in your existing programs. There are quite a few videos on YouTube about integrating Nik programs into workflow with LR and PS, for wildlife photography for example.
