Title: some startrails
Post by: screamer on July 27, 2012, 02:01:43 PM
Hi all,
here is a 371 frames startrail. About 3 hours of real time (every shot is 30seconds, iso 160, f2.8).

Just for information, i've first processed the shots in lightroom for gaining the stars and lowering down the light pollutions in the sky, because i'm in rome, and there's no pretty skys here :))) than gived an overall contrast and saturation and applied to all my shots. Then i've exported in tiff, and opene with the great (and free) startrails:

after that i've merged manually with some masks and some layer blen styles in photoshop, between the trails and the first shot (so as you can see i have a not so strong trail and the pointy stars of the single shot visible.
and that's all :))

if you like it you can find the other startrails i've done here:

And just about intervalometer, i've posted some days ago, in the features request section, this post: http://www.magiclantern.fm/forum/index.php?topic=1628.0
about some new interesting features in intervalometer function.
In that post i speak about changing the interval between 2 shots dinamically in the timelapse (for acceleration/deceleration purpouses, for example).
But doing this timelapse, i thought that should be incredible if you can also change all the values during the timelapse. For example a great effect with startrails should be to start with a very open aperture (and probably with high iso) and fast time (to have pointy and bright stars). And then decreasing every frame the iso/or aperture and increasing the time. The result should be something like a startrail with a big start and a trail that goes tiny...
should be great to experiment :)))

Great photo!

Thanks for including the details. I need to try out some startrail photography some day too :)
