Back in May I posted a photo of my first attempt capturing star trails. I recently returned to the same spot with a different technique to see if I could get a better result. This is a series of ten different pictures taken for five minutes each. I later layered them in photoshop to get this result! During my first attempt I noticed a lot of noise, or grainy specs throughout the photo. It was a 45min exposure at a high ISO. So this time I thought I would take a series of photos, shorter in time, but combined would make up the same time as the first. I added an extra five minutes to get longer star trails.
Next time I'll be including a little light painting where I'll fill in the trees with a flashlight!
