Silver efex pro 2 says unsupported image format

After adjusting the b&w image it looks something like the following. Then I select Filter->Nik Software->Silver Efex Pro 2. I optionally convert the copy into a Smart Object so that I have the ability to go back and change it later. I open this image in Photoshop then duplicate the background layer. So if youвЂ™re using Silver Efex Pro for your monochrome images as well as Photoshop, give this a try.Д«elow is an original image, pretty much straight out of the camera. ItвЂ™s far simpler than most of the other methods and I already have a lot experience with it. My ah-ha! moment came when I realized that instead of all the more-exotic techniques IвЂ™ve been using, I could just use Silver Efex Pro to create the luminance channel for my color images. Oh, and it has unique control points that allow one to make most of the same adjustments on isolated portions of an image. Not only can I control the mix of how the RGB and CMY channels contribute to the results, but it gives me terrific control over contrast, brightness and structure. I realized I use NikвЂ™s Silver Efex Pro 2 for virtually all of my monochrome images. Scott and I have developed pages and pages of notes documenting the various techniques for managing luminance separate from color.Д«ut recently I had a breakthrough. Sometimes we also paint (dodge and burn) specific areas in the luminance-only layers. These luminance layers may then be tweaked for contrast, sharpening, etc. Virtually all of the techniques weвЂ™ve learned from Dan, Lee and Mark involve steps such as finding and using one or more of an imageвЂ™s ten color channels (RGB,Lab,CMYK) as a replacement for the overall luminance control of the image. Likewise, setting a layerвЂ™s blend mode to Color will cause its brightness data to be ignore and only its color (hue and saturation) to override whatвЂ™s below. Setting a layerвЂ™s blend mode to Luminosity means only its brightness information will be used to modify layers below. Similarly, if youвЂ™re working in RGB color, Photoshop allows you to control luminosity and color separately by using blend modes. There are two principal methods for doing this: In Lab color mode the L (luminance) channel controls brightness and has no effect on color, which is managed in the a and b channels. One fundamental concept to all of our work is the separate processing of luminance (brightness) information and color. Our mentors (actively or passively) are Dan Margulis, Lee Varis and Mark Lindsay. The other day someone asked my, вЂњWhy are you using Silver Efex Pro for a color image?вЂќ A reasonable question IвЂ™ll answer here.ДЇor the past few months, Scott Loftesness and I have been researching and experimenting with a variety of post-processing techniques based on replacing RGB channels and using the Lab color mode. Over on Google PlusВ ( Facebook, too) I usually list the gear and post-processing apps I use for each image.
