I've seen plenty of star trails that have a 360 circumference, wondering if anyone knows exactly how to do that?
I've seen plenty of star trails that have a 360 circumference, wondering if anyone knows exactly how to do that? I know there's a method of taking numerous shots at way less exposure time but not sure of the details.... This is a 20 minute exposure - star trails surrounding power lines. Nikon D3200 / 18mm / f/5.6 / 1204" / ISO 200 - UV filter used to cut some of the light pollution. Post processed in Adobe Lightroom 5.6.
To get star trails that are 360 degrees, first you would need to face north or south, and be at a latitude that allows you to see the polar axis point Like the North star. It would also need to be above the arctic circle and in winter. 360 degrees takes 24 hours to go through, and of course it would need to be dark the whole time.
ReplyDeleteLooks like I'll have to settle for less then! I've heard say 400 - 500 shots at 30-40" exposure would produce thicker more pronounced trails, sounds cumbersome and file would have to be huge I'd think. Thoughts?
ReplyDeleteYou could never get a 360.. even a 180 would require 12 hrs of exposures... Its simple to do, use a FILM camera.. load it with some nice SLOW Film.. set it to B and lock it open for 8-10 hours on a tripod..
ReplyDeleteI have a Canon AE-1 Kevin Vincent that needs to be revisited! Actually just bought some 400 speed film last weekend but probably need slower I'd think. Good advice, thanks!
ReplyDeleteonce you get out to 20-30 min the speed of the film has little reference to exposure anymore... Reciprocity fails... Faster with faster films..
