Originally posted by philbaum Thats the best assessment i've seen. I was expecting the same detail being pulled out of Nik that Topaz provides, and you're right, its not there. I usually have to pull back on Topaz, but with Nik, you can't dial it up if its not there. Different programs, different formula. And it irritates me that LR can't do vignetting right. I still haven't seen Nik do much in shadow and hilight recovery. But it is fast. Kudos on the observations!
Thanks! Yeah I've noticed that the 'Detail Extractor' in Color Efex Pro 4 doesn't really do much past a certain point. While it will give you more of an HDR type look, it seems like it's merely raising the shadows and washing out the photo, which is why, I think, they stuck the Contrast slider in there with it, because you need to up the contrast to contradict the washout from the 'detail extraction'. With Topaz, however, you can enhance detail completely apart from exposure, and it does an excellent job at this, for the most part. Obviously you have to be careful of artifacting (and I've run into an unfortunate problem with Topaz and my K-5 iis files, wherein you have to be careful how far you push the file, else you get white dots popping up all over the shot, especially in shadow areas. No matter how hard I push the same files in Nik, this issue does not appear, which I can only attribute to Topaz working on a more micro level with the detail.).
On the whole I think that for the products I've used the most (Nik Color Efex 4, Nik Silver Efex, Topaz Adjust, Topaz B&W Effects), Topaz in general provides more powerful plugins.
One thing on the 'point' system in Nik in comparison to the local adjustments in Topaz; Topaz is better here as well, imo. While it might be quicker to select a point and make your adjustments, as long as they work, Topaz's brush tool for local adjustments is superior, as there is no guessing, and the edge aware in Topaz works extremely well. Doing selective color/detail can really become an artistic process with Topaz, producing an extremely detailed result. Of course this process is more involved and takes longer, but in the end I would think it more rewarding (it is for me anyway).
This all said, I've been using Topaz for about 2 years, and just started with Nik a little less than 15 days ago (my free trial is almost up... gotta pay... ugh!), so my contribution here certainly means less than someone with more extensive experience.
