I read a comment in another post on this subject but now I can't find the thread. So apology given in advance for the question. What is your preferred exposure to get the best color, least chromatic noise in the shadows at ISO's of 12800 or above. Do you expose right? Or expose for the shadows? Use the highest shutter speed possible to seek to minimize stray light? Is it possible for light leakage through the view finder, such as on a long exposure? I've reached a plateau where it seems that changes I've made aren't translating into better images. It may well be I've maxed out the camera capability.. Any comments on the subject.
