Interval timer and number of shoots(wired/wireless): Set the "INT" to the time you want and set the "N" to the numbers you want, if set 3s for the "INT" and 5 for the "N", the camera will take 5 pictures and the interval time between each is 3s QA: I need 50 pictures, the exposure time for each picture is 10s, and the interval time between each picture is 5s, how set? Re: (Camera in Bulb mode) Set the "BU" to 10s and "INT" to 15s, then set the "N" to 50 and press the "start" button. Why the "INT" needs to be set 15s instead of 5s as you wanted the interval to be 5s, as in the default programs of this remote, the interval time includes the exposure time. So the 15s of "INT" minus the 10s of "BU" results in 5s real interval time between each picture.
