If you have access to a scanner, scan your postcard at a high resolution (at least 300 dpi, 600 dpi would be fantastic).
Send an image file (a JPEG is preferred) or a PDF.
Try to take your photo in good light (natural light is best) and take the photo straight on. If you can, please place the postcard on a white (not lined) sheet of paper so it's easier to isolate the background.
If you camera shoots raw (?) please send the raw file. If not, a JPEG would be fantastic.
Remember, we need both sides.
