It's okay to expose to keep the shadows from going completely dark, but you usually shouldn't need plus 1 or 2. I rarely have to use plus EV with the K7. When I do, it's usually +.3. or sometimes +.7 when the most important part of the shot is in shadow. If you expose accurately at ISO 400, you won't get a lot of noise. The fur protesters pic I posted yesterday is ISO 400 in program mode with no exposure compensation. The doorway is pure black but there's no noise: http://photo.net/photodb/photo?photo_id=10637125&size=lg This pic is ISO 1250. I was in program mode, which picks f4 with the DA* 50-135. I went with +.7 EV because her face was shaded, and I pulled back the highlights in conversion and burned in the hot white papers on the table after converting: http://photo.net/photodb/photo?photo_id=10637141&size=lg This shot is ISO 6400, shot at the meter reading in aperture priority mode. There's noise in the deep shadows but the main subject is relatively noise free, and he was exposed correctly. No post work to speak of on this one, other than a slight application of PhotoShop noise reduction: http://photo.net/photodb/photo?photo_id=10541951&size=lg
