Ive been taking a lot of pics of people lately and I need some tips. I have a D70 and 18-200 VR. When I shoot them I use the "portrait" enhancing mode somewhere in the menus. I think it just makes the pictures and tones a little softer but I'm not sure. Should I use this? Or should I shoot normally and soften in photoshop (how is that done?) Also, should CPL stay on the camera when shooting people or is it negligable?
