I took this picture using back light and front light. This time I used blue gel on my back light which is using Canon Speedlite 580EX II Flash for Canon EOS Digital SLR Cameras. For the front light I used Tronic extreme standard reflector. I like this blue background. I was using my Canon EOS 40D and Canon EF 24-70mm f/2.8L USM Standard Zoom Lens.
