Star trail photography

I have loved star trail photos for quite some time now so I thought I would have a play.

This image of from a set of images taken last night, not the best night for star trails as there was a almost full moon but I needed to try out the theory.

The image below is a composite image from 55 photos stitched together, each photo was taken with a Nikon D5100 using the inbuilt “interval timer shooting” option.

The camera was mounted on a tripod and set up to take images with the following settings.

F-stop : 5.6

Exposure time : 15 seconds

ISO Speed : 1600

Focal length : 22mm ( I was aiming for 20 but hay ho)

The images where then stacked using StarStaX a fantastic little freeware application.

This is the resulting image:


Now there is lots wrong with this image, there is too much light pollution from the street lamps but it was able to prove the concept.

The next time I do this there will be no moon in the sky and I will be in a more remote location without street lamps and with a bit of luck it will be a lot nicer.

Fireworks 2014

It has been a while since I had the time to play with the manual mode of a camera as as the local school was having a fireworks night in my back garden I thought I would have a play.

So I set my Nikon D5100 up on a tripod got out the IR shutter release and had a play.

The base settings are:

ISO : 100

F-stop : F11

Focal length : 18mm

Flash : None

Shutter timing : 1.9 – 5 seconds.

With the exception of some cropping I have not done any post editing at the moment, I plan this week to take one or two of the images and play with them in GIMP / Photoshop and see what I can do with them.
