## What is DFsources?

Existing documents (PDF, PNG, JPG, DICOM, MP3, etc) can be added from local storage or by taking photos of paper documents. Once in DFsources, documents can have standard transformations (brighten/darken, rotate, skew) applied to them. User controls for redaction and certification are available. After study identifiers are applied, documents are sent directly to the DFdiscover study and attached as specified. Documents are immediately available for viewing in DFdiscover.
