I limit my Photoshop work to simple adjustments such as exposure, contrast, etc. The landscapes and other shots I take reflect the scene as seen, not a manufactured shot.
My mentors tell me "get it as right in the camera as possible, it's unlikely you'll be able to rescue a bad shot with your computer" how true is that!
Canon 5D MKII, 5D, L Lenses from 17-40 to 100-400, and a 24mm TSE MKII
In the main, landscapes, seascapes, the occasional wildlife, and some flowers.
