Camera Plus Pro is the one photography app that I purchased and have kept using. The company recently updated the app and they are having a contest for its users. With the update Camera Plus Pro 2.5 is fully iPhone 4 compatible, which means that it takes advantage of the devices new camera features. This includes the ability to control the iPhone’s LED flash on/off/auto functions.

The update also adds the ability to switch between front/rear camera; it has real-time preview for photo editing (adjusting photo properties such as Brightness, Saturation, Hue, Contrast, Sharpness, Temperature and Tint); added video exposure and white balance control in real-time; Bing image search integration; Live Share feature broadcasts images over wifi for easy viewing and sharing of the iPhone media library from any web browser; and it has improved video recording capabilities.

The company is also having a contest for its users, with the grand prize being a Leica D Lux 4 camera. The contest is set to end tomorrow, so if you want to enter, head over to the Camera Plus Pro website to enter.
