I just have a question that isn't intended for any illegal activity, but I was wondering: what is the difference between the FDNY 1620 Key and the 2642 key? Is the 2642 for putting the elevator into fire service?
By experiment, when I use an 800 ISO on a 6MP camera, it comes out grainy.
When I use a camera with 8MP and a 1600 ISO, it comes out grainy.
But... When I use a camera with a 10.1MP and 1600 ISO, it doesn't come out grainy.
