This image was done with two photos. The first I took on my roof of the cityscape of downtown Oakland. I made a diy heart brokeh lens hood from diyphotography.com (http://www.diyphotography.net/diy_create_your_own_bokeh). The second image I took was also on the roof as well with a flash, wearing black (that rhymes!) and me balancing on a chair in order to get as much black background as I could (which means less postprocessing work which I find to be a pain).
I used gimp and since I forgot to bring my mouse while visiting my friends and family, I painstakingly did it moving my finger very slowly on the laptop pad. Lots of undoing and redoing here.
Really, the reason why I wanted to do this image was so I could have an excuse to use the brokeh lens hood and see what it's all about. It was simple to make and created some cool results, although I thought all the lights were going to be hearts. All well, at least the majority of them are.
SO works about to start again which = more effective time management = more photos = more posts on flickr(http://www.flickr.com/photos/89337456@N00/) and hopefully here as well. :)
