Basic ISO question

It's okay to limit yourself, but I assume you have touched high ISO before turning away from it.

As an experiment, set your camera to JPEG. Use A or P, but set ISO to the max, set the picture mode to B&W, turn contrast to the max and turn sharpness to the max. Yes you read right, to the maximum value. Don't put it any lower than the maximum! Don't even think about going lower, you want to go to the extreme ends of what your camera can do. Then shoot at night, in a bar, on a ball, in the streets. The next time you can try color, but start from the basics. It's a different world that you can discover that way.

And then, if you say that's totally ugly, I can't seriously do that, then turn away and never look back.
