i just downloaded it this morning and was fooling around a bit with it. coming from a nikon dslr, what fcamera does on A FREAKING PHONE IS BLOODY AWESOME. the level of control it offers is pretty amazing. i have never seen this on any phone camera before. the out of focus shots you can take make for great subject / portrait images where you want the subject to be in focus while the background is blur. sure you can do it with the default camera app but that is automatic and it doesn't always get it right. having manual control is what makes this app excellent!! kudos to the team that developed this.
