JotNot is a new iPhone application that allows users to take photographs of documents using their phones and runs them through an advanced filter that makes them much easier to read. Here’s how it works: first, you take a photograph that you’d like to store as a photo (you also import photos). Then a blue box with four corner markers prsented, which you drag to the corresponding corners of the document. It then process the image, correcting for any issues with lighting, color, and even perspective (if you initially took a photo of your document at an angle, the final image will look as if it was taken front-on).
