Photography and assorted thoughts


Night Photography

I’ve made it out the last two weekends to do some night photography. This weekend, was more urban night photography, and I had a chance to try out what Tony Sweet was telling us, that you can overlay multiple shots to make a more interesting picture.

Here we took two pictures and used the lighten blend mode to overlay them. Since it was lightly sprinkling, we had some reflections working for us. The two shots were 25 seconds each, and since I had my iso set to 64, I didn’t need my neutral density filter. It does rely on the fact that you have a good tripod.

Tony had shown us a demo, where in the small town he was photographing in, where you could make a small town look like it had the traffic of the Las Vegas strip. In this case, the traffic on I-25 wasn’t bad either.

Since I was doing urban night shots, we didn’t need a cloudless sky.

In the next picture, I was out at Mt Evans, where I was trying out some software that allowed me to stack star shots and align them automatically.

Here this was 4 shots that I stacked. I was using Star Stacker Pro to do the alignment. This technique should allow me to use higher iso levels without paying the noise penalty. Thankfully last weekend, the clouds cleared up before nautical twilight. This 4 shots were all shot at 25 seconds each as well.
If you click on this photo, you can see how many stars are in it. I did get a comment on Facebook asking if there were really that many stars.

Mt Evans is still within the Denver light pollution, and later this summer I hope to take pictures on the other side of Rocky Mountain National Park where it will be darker.
