Some information about making time-lapses.
Remote timer shutter can be useful if camera does not have a timer built into it. The cheap ones with a wire usually works just fine. Program the remote timer to the shutter speed plus delay time of saving the shots. ND-filters or polarizers can be useful for longer exposures in ligting conditions. Use a tripod (of course) for timelapses or something like a camera slider, gimbal or drone.
Consider disabling Long Exposure Noise Reduction for long exposure timelapses, it might speed up the total delay between shots a lot. Also disabling photo preview between shots can speed up the delay. Maybe you could turn off the camera display while shooting, to save some power.
Better to have too many frames than not enough. Take into consideration the final frame rate, for example 30 or 60 FPS. Below is a list of a few scenarios and some ideas for the interval.
|Moving traffic||1 sec|
|Sunrise/sunset||5-10 sec||Manually change shutter speed.|
|Tides (near)||3-4 sec|
|Tides (far)||8-10 sec|
|Startrail||20-30 sec||Long exposures. Check delay times.|
Star trail & time-lapse
In picture below is a typical star-trail. We see trail around Polaris (North Star) because it aligns with the earth spin axis.
Shooting stars: ISO, focal length and exposure
In order to shoot stars at night a long shutter speed is required. Using manual-mode for the camera lets us adjust the parameters for shutter and exposure. Basically for this kind of shots a low ISO and f-stop is needed along with a long shutter speed. Here is some tests and examples:
|ISO-3200||F2.8||2.0 sec.||Lots of noise, too much light|
|ISO-3200||F2.8||8.0 sec.||Lots of noise, even more light|
|ISO-1000||F2.8||2.5 sec.||Useful result, when adjust contrast etc.|
|ISO-1000||F2.8||20.0 sec.||Too much light and noise (again)|
|ISO-200||F2.8||20.0 sec.||Less light but still some noise|
Another problem when shooting at night is fog on the lens. Camera and lens should be kept warm using a blanket or so, and check if lens is still dry when camera is processing frames.
