You can take snaps from directly within the app and there are various controls placed at your finger tips including autofocus, white balance, night shot, stable shot, timer and burst modes.

Once you've taken your shot you can apply additional effects including vintage, lomo, cinematic and pencil filters. Effects can also be combined to produce more interesting results. What's more, the attractive user interface makes it all very easy to set up and use.
With a great looking user interface and an impressive range of features, Camera Zoom FX is undoubtedly one of the best camera apps available for Android phones.
