Big Lens is a powerful photography application available for Android devices. It provides DSLR-level depth of field for your mobile phone camera, which is otherwise impossible to achieve. With numerous powerful filter effects, Big Lens is perfect for creating professional-looking photos on your phone.

Smart Focus System is one of the five super features of Big Lens, which allows you to focus your images with your fingertips without any previous knowledge of depth-of-field. You can use basic geometric shapes or a lasso tool to auto-focus your target, or you can choose advanced mode to manually define your focus area. Aperture Control is another exciting feature that lets you adjust the aperture with a single gesture to instantly change the blur level of the out-of-focus area.

Big Lens offers more than 18 filters that allow you to enhance color, increase contrast, or add Lomo effects. You can instantly modify the focus and blur area with your fingers using the Instant Focus/Blur Tool. Before & After Preview allows you to compare images and review them at any time during your make-over process. Lastly, the in-app purchase feature, Focal Separation, lets you unlock the new custom filter effect functions to achieve the ultimate artistic result.

Overall, Big Lens is an excellent app for novice or pro photographers looking to upgrade their mobile phone camera.
