PhotoDeluxe
From Just Solve the File Format Problem
PhotoDeluxe is a discontinued raster graphics editor from Adobe. Its native PDD file format is a subformat and extension of Photoshop PSD format. The extent to which it is compatible with PSD is unclear.
Identification
PDD files look like PSD files. The Image Resources segment may contain some blocks with a signature of "PHUT", instead of the usual "8BIM".
