Not based on traditional ISO thinking/standards with film and yesterday's dslrs. With today's more advanced cameras (current models and maybe one model behind), what do you consider high ISO? If someone says "how does it handle high ISO?" what ISO range would you think they were asking about? At what ISO do you start to hesitate and adjust the other variables? If your camera has a max ISO option for shooting in Auto ISO, what do you have it set at? How high is too high for shooting landscapes? Portraits? Including all noise reduction options - talking about final results - what is the highest ISO you have used and gotten what you would consider to be a good result? If you want to share the photo and/or the camera and settings that would be nice. Do you convert your high ISO photos to black and white to "save" them?
