If you miss the enhanced controls of a DSLR on your android smartphone, try out the Camera FV-5 app (Rs.199 for full or free, lite version). It gives you an interface similar to a DSLR camera with relevant information and one touch controls for ISO, white balance and exposure. The app also provides you with exposure bracketing, intervalometer settings and even lets you shoot photographs with long exposure. The images are processed in the background so you do not miss out on capturing the moment.
