Created by The Pixel Farm, developers of film industry-renowned VFX software, AirGrade for iPhone, iPod touch and iPad promises creativity with colour to everyone via AirGrade.co.uk, a new and free colour-grading engine.

The free app offers the ability to colour grade images emulating professional film and TV grading tools insist the makers. To grade an image using AirGrade, users roll a 3D trackball and rotate a radial wheel on their iPhone to adjust precise tonal ranges using Lift, Gamma, Gain controls – recognised by professional colourists as Shadow, Midtone and Highlights – plus a Saturation control for overall colour intensity. The result appears interactively on a Mac based computer, and on any other connected monitoring device, such as a digital projector. A shake of the iPhone resets the parameters, allowing a fresh grade to be made.

When the desired colour grade has been achieved, AirGrade's colour engine saves the grading data, in the universally-recognised ASC CDL format (.ccc file) that allows colour decisions to be transferred between colour grading and finishing solutions, and this data can be exported for professional use. The graded image is saved simultaneously to the iPhone's photo album, useful as a potentially fast visual reference.
