I am basically an unimaginative sort. I cannot previsualize a black-and-white photo ala Ansel Adams then strive to realize my previsualization in my editing. Rather, my fondness for Silver Effex Pro stems from my ability to run my photo through all the SEP presets to realize somewhat the range of the photo's visual potential. My query here is what workflow sequence is preferable that I follow? Do I process the photo first in its raw form utilizing Lightroom 4's excellent basic sliders, then pass it on to SEP? Or do I process the initial raw photo first in SEP, then when I've narrowed it down aesthetically to my preferred SEP preset do I pass it on to LR4 for fine-tuning with the basic LR sliders? Chicken or egg? Or do I do both? Seems a bit cumbersome that way, but to get a satisfying final photo, I guess it's ultimately necessary to employ multiple means. Anyway, any thoughts from those more (or less) expert and experienced than I would be appreciated.
