Buddy - funny you should mention focus stacking. Can't wait to see what you produce with your setup.
I have never tried focus stacking before but did so during my lunchtime break today.
Over the weekend I watched some videos on how to focus stack landscape images.
So I tried it of a couple of colorful plants in my back garden.
Each one 4-5 images, processed in LR then stacked in Photoshop before going back to LR for final tweaks.
