Fiddle with NIK software
Nik was recently bought by Google and their software price was substantially reduced. They used to have 2 versions, one was used as a plug-in for Photoshop and the other was a standalone. The plug-in was more expensive and could process images as PS objects. I use mine frequently because it's an easy way to get some powerful results. Effects can be painted on part of your image so you can reduce noise in some parts and retain fine detail in another. I use Tone Contrast quite a bit to punch up clouds and hazy mountains, etc. You can reduce any effect by adjusting the opacity of the change layer in PS, or add a layer mask to suit.
It is better to keep your mouth closed and let people think you are a fool than to open it and remove all doubt.
+1 used with Lightroom. I especially like the Silver Efex Pro. There is a good guide to the software by Jason Odell that you can buy too. I am reading through it.
What camera do I have? I rather you look at my photos www.flickr.com/photos/gavinz
Great software with a who knows what future. However, I think it's still worth owning as it is right now. As mentioned, the brush works intuitively, unlike with one other popular but very non-intuitive set of plug-ins I will not mention.
