Nepal Star Trails

I took this picture only a couple of hours before I was sick for two weeks. Yup, I was up on a roof in a t-shirt freezing by the end of the shot. When I came down from the roof I was shivering uncontrollably, and shortly after that I was spending way too much time in the bathroom.

No, I don’t really think that this got me so sick. Probably the flu, or some food, or something, but I was quite sick for a few days, and didn’t really feel “fine” for about two weeks. Anyway, more on the shot:

It was taken in Nepal, in a little town called Bandipur, down a very windy road west of Kathmandu. I was on the roof of the guest house we were staying in.

This is a multiple exposure image. I was shooting at f/4.5, ISO 200, for 5 min per exposure. I took seven pictures of star trails from the same roof that a couple of hours earlier I had taken the sun setting in the mountains picture. I used a simple cable release, and a timer. I then put them together in Photoshop.

They went together quite easily. I just stacked the layers and set the blend mode of each layer to screen. That worked well for the star trails, as only the stars show through, the black sky doesn’t, and you have the trails.

I then added more canvas room to the image, put the stars at the top, the mountains at the bottom. When I had them lined up how I liked them, I had a few stars in the mountains. I then created a mask, and applied a gradient to the mask, white at the bottom , black at the top so the stars didn’t show up on the bottom. I played with that a bit until I got it looking the way I wanted.

Thats it. I have wanted to play with star trails before, but it is amazing how little light pollution it takes to ruin the image. Anyway, it was fun.
