Hi everybody! I'm pretty new to timelapses and I am really enjoying LRTimelapse. So far, I have only been making tests indoor, but now I'd like to go more serious: timelapse of the Milky Way! :-) From what I read on the internet, it is pretty challenging and I'd like to ask you some help. That's what I found on several pages/sites/forums:
- shoot RAW
- manual exposure (minimum F number, i.e. 2.8, and about 20 to 25 seconds shutter speed, ISO 800 to 1600 or higher if the camera works fine with it)
- manual focus at infinity
Now, I have some stupid questions:
1) Do you have any suggestions on the interval between one shot and the next one? I'd like the timalapse movie to be as smooth as possible but I also would like to reduce the number of exposures to the minimum to save the battery.
2) On the battery side: I am using a battery grip with two batteries in it, do you have any idea on how long will the batteries last? 20 to 25 seconds exposures may be very demanding for the battery and I'd like to avoid spending the night outside looking at the display :-)
3) More on the battery side: does the battery last longer if I shoot JPEG instead of RAW?
4) In the event of a looong timelapse which lasts until sunrise, I'd like to take shots of the holy grail as well. I've seen the wonderful tutorial about how to cope with ISO jumps in LRTimalapse, but I have a more basic question: where do these ISO jumps come from? I mean, I always thought transitions between daylight and night and viceversa should be shot in aperture priority: am I wrong? And in case you shoot manual also in these challenging conditions, do you set the exposure for the initial conditions or for the final conditions?
Ok, I know there's a lot of stuff in here, but I hope we can start the discussion together.
Have a nice week,
Dan
