Dec 22, 2011 - Independent developer Klemen Kloboves is pleased to announce a free trial of Contrast, an app designed to help users scan documents using a digital camera. You can try Contrast without hassle on the product website, right from your web browser. Contrast uses a clever algorithm to enhance images, ensuring a white background and black text. Printing the resulting image requires much less ink and text is easier to read. Contrast is easy to use and requires almost no configuration.
