CamScanner is a breeze to use, and you can test out the free version via the Market link above. Snap a photo of your document and pull up the cropping tool. The app will auto-detect the edges of the paper, but the slick drag-and-snap guides will help you fine tune the dimensions.
The processing enhancements are smart, and will compensate for low light and bad focus reasonably well. Though the app generates a cropped and toned image, it will also hang onto the original photo — handy, in case you accidentally cropped your boss’ name off the letterhead.
The app has built-in integration with Google Docs, Box.net and Dropbox, but for the less fancy among you, it’s easy to pipe scanned docs straight into email.
The main issue we encountered was with PDF creation. The original image is stored as a JPEG, but the option to convert it to a PDF simply opened the phone’s default PDF viewer. The file is viewable, but we found no apparent way to save or share.
The paid version promises to make things easier in this department, but you should see how the free version performs on your device before purchasing.
