Lightroom is nowhere near photoshop.
I spend hours every day with PS.
Lightroom is usually used as a DAM program and it’s enhancement stuff is stripped from Adobe Raw. But if you want to make production quality work, PS is the standard.
I only shoot in RAW myself and actually prefer photoshop (bridge).
I’ve been playing around with Picturnaut for HDR photos. Its pretty minimal but its fine if you like the low key HDH stuff without all the tone mapping.
