Intervalometer timer shot suppose to work in bulb mode where ur shutter speed is more than or equals to 1 second. If u are not in bulb mode, it will still follow ur camera setting.
Sorry, I don't quite understand your first sentence... :embrass:
ya if exposure time is less than 30 secs it can be set in camera. but how about if its more than 30 secs in bulb mode? can you set the exposure time in the intervalometer?
Ok. For Intervalometer (specifically phottix nikos but should be similar for other brands), there are a four settings you can set.
1. Self timer count down. This means how many seconds before you take a shot.
2. How many seconds between the interval of each shot.
3. How long exposure for each shot taken. (note that minimum is 1 second, cannot go anyway faster)
4. How many frames you want to take in the entire cycle.
These 4 settings works hand in hand, not contradicting. However, you do not need to set all 4 settings to work.
For e.g.:
I set 5 seconds self timer, 4 seconds interval, 2 seconds exposure and 99 frames.
This means:
i. The first shot will start 5 seconds after I start the intervalometer
ii. Expose for 2 seconds
iii. Wait for 4 seconds after the first shot ended
iv. Repeat from step ii for another 98 frames.
I can also set 4 seconds interval and 0 frame, which means it will take exposure timing set in your camera (not in bulb mode), trigger the first shot immediately after you start the intervalometer, wait for 4 seconds, then take the next shot, and will repeat endlessly (Of course, till your camera batteries run out or your memory goes full).
I hope this summaries all you need to know about intervalometer. I will still think nikos is the better one to choose. Besides the reasons I stated before, it also the one with the largest font in display and the brightest backlight when using in the dark. The only down side is that it's slightly more expensive than other 3rd party brands ($75 compare to $60), but it still way cheaper than the OEM from the various camera manufacturer.
