For those of us who use's Capture NX2, it is disappointing that Nik Software's Filter Programs are not available for NX2, with the exception of Color Efex Pro, which I use frequently. I have seen mentioned on other forums that the Lightroom versions of the other Nik software can be run as stand-alone programs. This means that they can be called from within Capture NX2, which converts the file you are working on to a TIFF and passes it across to the program of your choice. I tried this out, and it worked fine, so I purchased Nik's HDR Efex Pro.
The one problem with this is that Capture NX2 only allows you to specify one 'Edit With' external program at a time, you have to go into the setup and change the program each time you want to use another external editor. I saw another thread on another forum where someone had written a Batch File to call a number of external programs. You set the batch file as the 'Edit With' program, and when you called it it presented you with a list of your external editors, for you to select. This appeared to work OK, but being a batch file was a bit messy, running in a DOS window. I had a look at it and decided to create a small program to do the same thing using VB6.
I have now written this program, and offer it to anyone who would like to test it. It allows you to specify the name and path of your external editors, and send a file to any one of them from within Capture NX2. No Guarantees that it will work for you, but it's probably worth trying.
If anyone is interested in trying this out, send me a PM and I will email the program to you.
