| 説明 | I've been wanting to do another star trails photo for a while. I failed last night, so I did some homework. Here's what I did/learned:• I took 33 photos• total exposure time: 1 hour, 45 minutes• each photo was about 3 minutes long• f/3.5 (which was counter-intuitive, but that's what everyone else does. The stars are brighter with a wider aperture.)• ISO 200 (that's the lowest my dSLR gets)• manual focus (on the house at the bottom)• Photoshop: changed layer properties to Lighten, aligned photos (barely at all), masked out top left corner (it was purplish). I found that an exposure longer than 4 minutes makes my photos bright in this corner. Hmm...This will officially be my earliest photo-a-day blog posting. It's 3:32 am. I had to wonderful idea to start at 1:00 am with this shot.Day 123 |
