In two previous articles I covered the most common problems that face anyone doing long exposures. In part 1 of 2 I discussed: Poor Focus, Dim Stars (low contrast), Strange Colors and Pink or Purple glow. In part 2 of 2, I tackled gaps in star trails, and noise.

Landscape Photography Introduction It’s that time in the evening, when the sun has set, the clouds have put on their show, and the first stars are beginning to shimmer through the twilight blues. It’s one of the most peaceful and tranquil moments of the day, second only to predawn, but you’re probably packing your bag to make sure you get back to the car before darkness descends.

Lets Go Streaking, a Guide to Star Trails : Liquid in Plastic – Photography and Words by Dan Newton Ever since the first time I looked in a book with long-exposure photography, I’ve loved the look of trailing stars in photographs. The idea is simple, expose for a long enough period of time to record the rotation of the stars as the Earth spins. My own attempts were never very successful using film due to the negative effects of reciprocity and my lack of technical skills and patience. Even later, when I finally got a digital SLR camera with the battery life to pull off an hour long exposure, my star streak photos were always sub par, riddled with technical and aesthetic problems.
