Patrick. How are you editing HDR or EXR in Photoshop? anyway, The way I use ( and the reason ) 'Select Edges' is for very subtle color enhancements , shading and hilighting.
Here's what I do; 1) move my image to a new window with trans bg. Duplicate the image, Turn off the top image, select the bottom one, use the 'select edges' plug-in' ( choose the effect you want ) Now.. The most important step, click on select > inverse and click 'delete'. You are left with a line image that defines the contrasts of the orig photo. You can increase the 'drawing' by duplicating the layer and merging, you can change the color, add a gradient, add any layer style, blur, Place it on top of the photo and let your right brain kick in.

here's some examples of how I use it. the top is the orig. illust. the center has a colored and blurred select edge effect over the top and the small one has the select edge line under the image then a gradient brush ( as eraser ) vignetting the image. These effects have little or no value for photos, but for illustration, the sky's the limit
