In answer to the questions; exposure time was only 30 seconds as that was the limit on the Olympus EP1 unless you have a cable release for 'bulb' which I didn't, because of this relatively short time I increased the iso to 400 for a better exposure. Each photo is one image, no filters and I'm afraid I don't no what subtracting a dark frame is so no I didn't do that. Take a look at http://green-gallery.blogspot.com/2011/01/turning-night-into-day.html and further back in my blog for more night photos with my 'proper' camera and cable release. But nothing beats the Grand Canyon stars.Dave Greenhttps://www.blogger.com/profile/05657374540473599821noreply@blogger.comtag:blogger.com,1999:blog-3714424959924873404.post-78672868292727886932011-05-24T20:11:22.182+01:002011-05-24T20:11:22.182+01:00Great photos!
