Time Exposures

So, I decided that one aspect of the photography world that I would love to get to know better is time exposures. Night time streets, skyscapes, lightning. I've tried this technique a few times but have not yet mastered it.
Here's a couple of websites to check out that elaborate on the technique a little bit more.

I've also found a few pictures that demonstrate time exposures at their finest:

Copyrights asside, (use your imagination) this is a beautiful image. I love how the moving stars seem to give the tree a halo.

As soon as I can find a waterfall, I'm going to attempt this technique (oh flat flat Manitoba and it's lack of waterfalls). I love the softness and flow of the water and I can't wait to try to capture an image like this one.

Of all the styles of time exposure photography, storm chasing and lightning pictures have always been up there on my favourites list. This is the style of time exposures that I have attempted the most, although my first few tries were unsucessful. I'm excited to learn more about it and give it another go, although it's going to have to wait until next summer.

Please keep in mind that the photo's that I have posted are copyrighted material. The artist for each photo can be found on the linked pages.

Happy learning all!
Until Next time!
