After viewing a few tutorials on HDR processing (or should that be tone-mapping?), I thought my 3100 might be natively configured to take an automatic bracket of three shots with different exposures, but it turns out that this can only be done manually. However, it seems that this capability, or lack of, is really only due to Nikon's programming of the camera's firmware. In other words, if the firmware was rewritten to include AEB, or automatic exposure bracketing, the D3100 could do this. Is this correct?
