Here is a fine example of how you can really take advantage of your phone camera instead of spending hundreds on a professional DSLR. These spectacular pictures were taken with a Samsung Galaxy S2 by Stu Kennedy in the UK.
Check out the video at the bottom all in 720p HD. Stu carried out the editing with Adobe After Effects 5.5 and Sony Vegas 10.
I encourage other Android users to use their phone camera to its fullest by using the wide array of camera apps that there are out there. You can achieve some beautiful effects without having to spend a fortune.
