Mill Colour is described as 'The Mill is an award-winning visual effects company; in fact we have a BAFTA and an Oscar among our many trophies. As the leading innovator in our industry we are now proud to present Mill Colour, a unique photo grading application' and is an app in the Photos & Graphics category. There are five alternatives to Mill Colour for a variety of platforms, including iPhone, Windows Phone, iPad, Windows and Android. The best alternative is Adobe Photoshop Express, which is free. Other great apps like Mill Colour are Pixlr-o-matic (Free), Helicon Filter (Paid), Lo-Mob (Paid) and Polaphoto (Free).
Helicon Filter is a complete photo editing solution for the digital photographer. Its easy and intuitive interface, live preview feature, and contextual help ensure an easy start in photo editing for beginners.
Polaphoto brings back the good old days of instant film photography. Which is a little ironic, since there's nothing more instant than the digital photos you're taking with your awesome Windows Phone. Nevermind!
