Finally after a few weeks we had some clear nights so I headed about an hour away from my home to shoot this abandoned farmhouse. One thing that we have a lot of here in Vermont is old barns and farmhouses and this one sits in an area that is just great for night work… No light pollution and a nice subject to place in the frame underneath the star trails. It really is a great feeling to be under the stars by yourself on a country road with no one bothering you. As an added bonus the fireflies were out in force on the night I was here adding an interesting element into this frame!

I challenged myself on this one as I was shooting during the blue hour at twilight and I shot multiple exposures of the house for later blending. In my rush to get to this spot I forgot any lighting implements so to begin processing this star trail I first started with two shots…One for the sky and one for the house at a higher ISO so that it would be more than just a silhouette in the frame. This blended image was used as the base to layer all of the other images in the series. The added bonus in this shot were the fireflies…Each frame on its own looks quite uninteresting but when they are all combined it adds a bit of magic into the shot.

I was a little hesitant to share this one as my white balance was a bit off but the more I looked at this one the less that imperfection bothered me. I was shooting at twilight during blue hour so the light did have a really pleasing blue quality to it. The processing for this one went as follows…

1. I first blended two shots for my base image of the house and sky. One image was shot for the house at ISO 800 just to bring up the shadows and add a bit of light onto the house…I wanted to see the home not just a silhouette. I brought both images together with a gradient and made some tweaks to this base image in Lightroom for white balance and lighting.

2. Once I was done with the base image I imported the base shot plus all of the other images in the series into a separate folder on my computer.

3. In Photoshop CC I then chose File-Browse in bridge- Then choose the folder you placed the series of images into. Select all by right clicking on the first image which should be your base image and the start of your star trail series.

4. Once all of your images are highlighted in Bridge choose Tools-Photoshop-Load files into Photoshop layers. Photoshop will place all of the images onto one canvas in their own separate layers. Here you will have to wait a few minutes depending on how many images/layers you have.

5. Once all of the images are layered in Photoshop highlight and select all of the layers and then set the blending mode to lighten. Before your eyes the magic happens and the star trail will appear!
