As many would have already known, I use both the Capture One Pro 7 and Adobe Photoshop Lightroom for my post process and tethering needs. You can read more about my Adobe Photoshop Lightroom process flow here.
I also shoot a lot of white and/or black backgrounds of recent, and I have developed these Adjustment Brush(k) presets to use with Adobe Photoshop Lightroom.
