Hi everyone! I'm learning something about creating HDR photos using the bracketing feature on my D300. I've enabled the function button on the front to bring up the bracketing option on the lcd screen. But I'm wondering why I can't dial "2" stops between shots. It only goes to "1"or some fraction of that. I'm not sure I'm being clear. If not, let me know and I'll try to clarify. Thanks in advance, folks!
