RAW by 500px!
 
I was updating my apps when I noticed a free app. This app was said RAW. When an app says raw it really gets a photographers attention. I was curious! So I checked it out. Oh boy! You have pretty much for free the power of manual control for your cell phone! Let's open it up and see what this baby can do!!! Shall we think about a photo contest?
