What are the different filters available?

| Filter | What Genius Scan does | Good for … |
| None | No filter will be applied | You want to keep the original untouched. |
| Black and White | Genius Scan clears up the background and turn the scan into black and white. | Mostly black and white documents such as receipts, contracts, official documents etc. |
| Color | Genius Scan clears up the background but keeps the colors. | Mostly black and white documents with some color: documents with letterheads, logos, whiteboards… |
| Photo | Genius Scan bumps up the colors so that the photo looks very vivid. | Postcards, photographs, paintings… |
