A lot less than you might think, haha! I used to edit so much. Now, I just do a very quick prep in Lr and then I like some filters by Exposure software that I use at low opacity to adjust the colors. I can do a complete edit in Lr alone in about five minutes. If I am feeling fancy, I might dodge and burn or hours, but that is because I find the process of dodge and burn very relaxing.
I love textures a lot again. I'm enjoying adding grungy textures, which is a throw back to 12 years ago. I love it and so I am doing it, haha! I love the results when printed on fine art paper.
