So my E-PL2 has this tone control thing. Basically, it allows you to set the tone curve, which affects contrast and brightness, of the image. I've been playing with it some just to try it out. It allows me to push shadows up and pull highlights down. So far it doesn't appear to effect exposure. See, when I was playing with the contrast setting for the various color/mode types, this does some similar things too. One thing I noticed is that if I pull the shadows all the way up ( +7 ) and highlights down ( -7 ), that the WB on the final image did not look right. I could get the overall tone back, but the WB still looked wrong. Keep in mind, in my testing, I was shooting with the same aperature and shutter speed. The shadows look identicle to when using auto gradation to hold shadows, which are slightly noisy when setting the tone curve to +7. Has anyone had any success with changing or using this feature of the camera?
