My workflow is similar to Brant's.

I do initial culling on site in camera, then import to LR and continue culling. Next, process in lightroom and export the ones I like to jpeg. I have photoshop, but rarely use it. I've also been trying to integrate DXO into my workflow via LR export, but find I'm a creature of habit and continue to go the LR only route. Why did I spend the money?????
