Hey, don't be critical of this kind of experimentation! Some day you may want to take a photo of a relatively even toned grey subject at an effective ISO of 6400, and then you'll remember this adventurous soul (who probably needs to get a life) and you'll realize that you shouldn't use more than an effective ISO of 3200. Be kind to those who have gone beyond normal photography to artistic exploration of the inside of lens caps and grey walls at midnight on a dark night. (:~]
