My inexperience is going to show here but sometimes to get the job done you just have to put it out there and hope you don't get beat up too badly so here goes.
I did a shoot yesterday and a couple of the photos I got were against a somewhat "busy" background. Of course I opened the lens up to try and blow out the background and I was successful to a point but only to a point.
When I got the photos into PS I tried to selectively sharpen only the model or her upper body/face but I had limited success. I don't want to sharpen the entire image because of the background but I couldn't figure out how to efficiently and effectively do a selective sharpening (I tried the lassoo, the marque, etc) and I am hoping someone has done this before and can give me some pointers on how to do this and get good results.
