I tried doing some long exposures a few weeks back with my D80, I got the exposure from cranking the ISO to ‘3200′ (hi1.0) on my d80, then opening the lens to f/2.8 and I got a shutter speed of 1 minute. That being said I did the math, of getting to ISO 400 (3 stops) and f/8 (3 stops) for a total of 6 stops of light less than before. That being said I need 64 minutes on the shutter! The original ISO 3200 shot worked, but was horrible quality, and really bad noise. I figured, that the 64 minute exposure would work. No. I did some research and found that the D80 has a maximum recommended exposure time of just 30 minutes. So much for 4 hour star trails, I guess I’ll be breaking out the Canon FTb for those ones. Would a Holga work? Maybe with some elastic bands.
Some pictures from my field trip to Goldstream Park with school. I’m finding it somewhat of a disappointment. I’m not learning nearly enough to keep me interested as of yet.
